What Is a Surge Protection Device?
A surge protection | ALLTech device is an electronic device or appliance meant to protect electrical equipment from sudden voltage spikes in alternating current (AC) circuits. A voltage spike occurs when a direct current (DC) stream flows over a potential difference, which is typically measured in amperes or amps. When the input load conducts current at a higher ampere or amp rating than the device’s maximum load, a voltage peak is generated. This is referred to as the overload condition. The device is designed to recover the power consumed during this time period so that normal operations can continue.
A surge protection device is commonly used in business to avoid expensive and devastating electrical losses. It is important that an over-voltage condition is avoided as much as possible, particularly for appliances used in industrial settings. The device, connected to the circuit either by a grounded conductor or a surge protector, is able to detect the overload condition and either turn off the device or reduce the voltage level until it matches the preset output. An example of this is the use of an adjustable clamp on a surge detector. The clamp allows the device to be set to a lower setting if it senses an overload, such as when the circuit is being operated with too much power or the breaker has tripped.
The Best Protection
Industrial, commercial, and residential applications often require protection for appliances and equipment that are vulnerable to high voltage fluctuations. For these applications, one of the best options is the use of surge protection devices. Industrial applications include machinery, equipment, and structure that are exposed to varying levels of alternating current (AC). The application most often requires the use of protective devices that protect sensitive equipment. Examples of these devices are air conditioners, refrigerators, computers, and other electronics that are susceptible to high voltage fluctuations.
In order to prevent damage from surges and fluctuating loads, most utility companies employ the use of electricity distribution systems. These systems include circuits that isolate individual electrical appliances or structures within an entire building. The circuit protects the power distribution from damage caused by heavy electrical loads, such as surges and fluctuation. One example of a surge protection device that prevents damage is the lightning arrester. A lightning arrester is used to shut down the power distribution to an electrical appliance in case of a breaker being tripped. This option is especially useful in rural areas where multiple appliances could be affected by a storm.
Different Types Of Surge Protection
A lightning arrester is placed over the incoming electrical power cable. It contains a circuit that consists of a variable resistor, which allows the lightning arrester to adjust the voltage of the incoming current to prevent damage to the insulation. When the resistive value changes, the current will vary according to a predetermined pattern, such as a sine wave or a log graph.
The lightning arrester is then placed over the power supply and connected to a preset source of power, such as the fuse box. This connection is necessary in that the circuit will shut down if the resistance to the flow of power is detected. A surge protection device is used to provide protection to an electrical appliance, such as a laptop computer, when the power supply is interrupted.
