The operation of the compressor directly depends on the quality of the electricity it is supplied with, since its main component is an electric motor.
It is the compressor that most often fails prematurely, and surges are probable reasons for this outcome. That is why if you do not want to install a surge protector for the whole house, you can find a much more affordable option in the form of a power surge protector for the refrigerator.
Inexperienced users should remember that the starting currents of such equipment as refrigeration compressors are times higher than the rated ones. Then the power of the protector will be enough to start the refrigerator with both low and high voltage.
A joule rating indicates how much energy the surge protector can absorb before it fails. The higher the number, the greater the protection provided. Are you protecting an expensive refrigerator? Obviously, the higher the value of your equipment, the higher the quality of surge protector required. A surge protector with to joules will provide sufficient protection, but consider the highest joule ratings— and above—for home appliances.
Modern surge protectors have many technical characteristics, however, power is of fundamental importance among them. To calculate the power consumed by a device from the network and, accordingly, the power of the protector, the rated power of the device is multiplied by the multiplicity factor. For example, a domestic refrigerator has an average power of W, a multiplicity factor of 5, then, accordingly, at the time of start it will consume W.
Yes, it may happen. The refrigerator, of course, is not the most economical appliance, but high power is not recommended for its operation. Another thing is that it includes a compressor, and therefore an electric motor. The compressor operates in a cyclic mode, that is, it constantly starts and stops.
Each start of the electric motor is accompanied by high starting currents that are several times higher than the nominal one, and therefore a more powerful surge protector should be installed for the refrigerator, for example, 2 kW, or another model,which in accordance with its technical characteristics, has excellent overload capacity, allowing a short starting load.
Such a parameter as the operating stabilization range means much more. Exceeding the specified range leads to the shutdown of the protector, which helps protect the consumer when the device cannot stabilize excessively strong and dangerous vibrations. There are three: the most affordable voltage relays, more expensive uninterruptible power supplies and surge protectors, which in terms of protection and price are something between the first two and, accordingly, optimal for many purposes.
To make total protection of your house may be rather costly. The great option is to protect only expensive and sensitive equipment. And which one usually has one of the highest prices among all the equipment in the house? A fridge. Surge protectors are divided into several types, each of which has a set of individual features. From the point of view of directly technical characteristics that can be measured in numbers, only one is necessary, power.
First, you need to decide on power. For example, a surge protector has a power of 1 kilowatt, which is clearly not enough for the starting loads of compressors of rather large two-chamber refrigerators.
However, the manufacturer guarantees an overload capacity of up to 3 kW for 8 seconds. Of course, modern refrigerators are more reliable in terms of safety and energy-saving, they have a significantly advanced automatic control system the refrigerator independently selects the operating mode taking into account fluctuations in the ambient temperature. But, do not forget that even the most advanced refrigerator still remains vulnerable in terms of network drops. Because, the more complex and modern technology, the more critical it is to the quality of the power supply.Return to Electrical Article List.
A power surge is one form of electrical power disturbance. There are four main types of power disturbances:. Power surges are generally considered to be the most destructive of the four types of electrical power disturbances.
Leading Causes of Refrigerator Damage
They are very brief, usually lasting millionths of a second. Power surges can vary in duration and magnitude, varying from a few hundred volts to several thousand volts. In the United States, most homes use electrical power in the form of volt, 60 Hz, single phase, alternating current.
Contrary to what most people think, the voltage is not delivered at a constant volts. With alternating current the voltage rises and falls in a predetermined rhythm.
The voltage oscillates from 0 to a peak voltage of volts. Most appliances and electronics used in the United States are designed to be powered by this form of generated electricity. However, during a power surgethe voltage exceeds the peak voltage of volts as seen in the graphic below A spike in voltage can be harmful to appliances and electrical devices in your home.
An increase in voltage above an appliance's normal operating voltage can cause an arc of electrical current within the appliance. The heat generated in the arc causes damage to the electronic circuit boards and other electrical components. Smaller, repeated power surges may slowly damage your electronic equipment. Your computer or stereo may continue to function after small surges occur until the integrity of the electronic components finally erode and your satellite system, cordless phone, or answering machine mysteriously stops working.
Repeated, small power surges shorten the life of appliances and electronics. There are several sources of power surges.
They can originate from the electric utility company during power grid switching. A common cause of power surges, especially the most powerful ones, is lightning. Power surges can originate inside a home when large appliances like air conditioners and refrigerator motors turn on and off. There are over 20 million cloud-to-ground lightning strikes detected per year in the 48 contiguous states of the US.
Power surges can enter a home through several paths. In the case of lightning, it can take the path of the cable TV or satellite dish cable, through the incoming telephone lines, or through the incoming electrical service line. Knowing that power surges can take several paths and do not have to enter through the electrical panel indicates a good surge protection system should include:. When deciding on what type of and how much surge protection is needed, each house and its contents should be assessed individually.
An electrician knowledgeable about power surge protection systems and the history of problems in your area is a valuable resource. We cannot, however, guarantee the performance of all items demonstrated or described in all situations. Always consult an experienced contractor or other expert to determine the best application of these ideas or products in your home.
There are four main types of power disturbances: Voltage dips also called "sags" or "brownouts" Electromagnetic interference Radio frequency interference Power surges also referred to as "voltage surges" or "transient voltages" Power surges are generally considered to be the most destructive of the four types of electrical power disturbances. Power surges are spikes in voltage. No matter where you live, your home experiences power surges. Protecting Your Home From Power Surges Knowing that power surges can take several paths and do not have to enter through the electrical panel indicates a good surge protection system should include: Protection of the incoming electrical service Some type of protection of phone lines and cable TV lines Point-of-use surge protectors at sensitive and expensive appliances When deciding on what type of and how much surge protection is needed, each house and its contents should be assessed individually.

Some are designed simply to lay flat against the wall unit while others are cord based. Each of these are equipped to handle high amounts of wattage and many feature over voltage disconnection.
Surge Protector For a Refrigerator
Some of these also feature various operating modes along with safety cycles. Take a look at the table below to see the key features and ratings. On the front face of the protector is one single outlet. The amount of power a refrigerator generates is effectively managed here. What we like most about it is that there are 3 different modes in the safety cycle of the Nippon. This allows things to get back to normal and then it will turn out once normal operating power is restored.
The Nippon has 3 indicator lights across the top of the unit. This tells you whether the power is on, off or in standby safety cycle mode. Get more details here. This is a single outlet with a 3 prong input.
Now this is a simple wall tap plug meaning that you can plug this into the outlet without the need of long power cords. The primary benefit much like the Nippon is that it saves on space. With that feature you can easily push refrigerators, ovens and other big appliances right up against a wall and cut down on space. Most importantly what the CSBW is determine spikes in power and protect your equipment. Overall we definitely recommend it especially if you want to use it for other types of units like laptops, routers, microwaves and other small products.
If your appliances are at a weird angle then that works perfectly. Best of all is that 5 outlets opens up more opportunities to plug things in. That means a fridge, oven, microwave, hey even a coffee maker if you wanted to. The total is watts of capacity which can power up an entire kitchen.An inverter is an electrical device that converts DC battery power into volt AC household power to run appliances such as a refrigerator.
Inverters are available in different power capacities and some are powerful enough to operate refrigerators. But before you run out to buy an inverter, you need to figure out how big an inverter you need and how much battery capacity it will require.
Before shopping for an inverter, you need to know the power draw of your refrigerator in watts. This information is found on the manufacturer nameplate, expressed as amps or watts. If the plate gives the watts, you are home free. If amps are given, convert amps to watts by multiplying the amps times the voltage. For instance, if your typical 16 cu. That is your running wattage. A fridge motor also needs a jolt of about three times its running wattage to start up, but this surge is needed for only a fraction of a second.
To run this refrigerator, you will need an inverter that can handle watts for long periods and a surge of 1, watts for a split second. A typical inverter offered at discount stores or home centers provides 1, watts continuous AC power and 3, watts of surge power.
This unit should run a typical 16 cu. To find DC amps, divide AC running watts by 12 and multiply the result by 1. A fridge needing AC running watts will draw 55 DC amps. Lead-acid rechargeable batteries are rated in ampere-hours. A typical battery rated at ampere hours can deliver DC amps for one hour before it runs out of power. In general, you risk damage if a rechargeable lead-acid battery is drained below 50 percent of capacity, so you safely can draw amps for only 30 minutes.
A fridge drawing only 55 DC amps can be run for about 60 minutes of continuous duty off a ampere-hour battery. Refrigerators run intermittently, not continuously, so you need to determine how many minutes out of each hour your refrigerator actually runs.
If your refrigerator draws 55 DC amps for 20 minutes out of each hour, you will need to recharge your battery after three hours of refrigerator operation. A second battery will keep your fridge running while you recharge the first battery. Herb Kirchhoff has more than three decades of hands-on experience as an avid garden hobbyist and home handyman.

As many adjusters know, a damaged refrigerator can quickly become a headache, since damage to this common appliance can require a lot of complex research. You need to know whether or not the refrigerator can be repaired, and you need to establish food-spoilage coverage and estimate total claim costs.
While the average lifespan of a standard, full-size refrigerator is around 17 years SF Gateone-time occurrences or a lack of maintenance can drastically decrease their longevity. High Voltage Surge was the leading cause of peril to refrigerators assessed by StrikeCheck last year. When there is an increase in voltage from a power surge, it causes an inrush of electrical current within the refrigerator. This surge generates an excessive amount of heat, which can damage multiple parts of the refrigerator.
Three components in particular that we often see damaged by a high voltage surge are the control board, the compressor, and the ice maker. The control board is the most sensitive component in the refrigerator. Therefore, it is easily damaged when a surge of electrical current creates excessive heat.
Refrigerators with a damaged control board can often be repaired, as the board is relatively inexpensive and easy to replace on its own. While not damaged as often as the control board, the compressor can also be damaged by a powerful high voltage surge. A strong electrical event can damage the windings that provide the start and run functions of the compressor, causing premature compressor failure. Because the high cost of replacing the compressor, the refrigerator often requires replacement if the compressor is damaged.
The ice maker assembly is relatively inexpensive to replace and, provided the parts are available, a refrigerator with this type of damage can often be repaired.
Refrigerators typically last 17 years or longer with little routine maintenance. However, without this maintenance the lifespan can be much shorter. As with any mechanical component, the functionality of the compressor diminishes with age. Eventually, the compressor may not turn and will become mechanically locked. When this occurs, you will hear a constant humming sound from the compressor as it attempts to start, and it will be very hot to the touch.
If the compressor is constantly starting because the refrigerator is filled to capacity or the coils are dirty see section on dirty coils belowthis condition may occur prematurely.
