What is the overvoltage?
The overvoltage current is a sudden increase in current caused by an imbalance voltage. In general, a sudden increase in sudden increase and the electric current is the rate of charge flows. The current is usually measured in amps (a). If the direct current power cord (DC) carries 20 A during the constant load conditions, a current increase of about 50 may be possible and under transient conditions, for example during power supply. The voltage imbalance is the difference in the electrical potential that causes surge currents.
There are many ways to avoid devices due to overvoltage currents. The overvoltage current can be internally or externally generated. The interventioned overvoltage current is usually the result of the capacitor overvoltage current, resulting in a condenser or condenser of a previously charged sudden flow flow to balance the capacitor voltage to the source circuit. Despite experiments, the proof of the Righting Shicge device, there is always a way to induce overvoltage currents into the power device. NThe devices can have power feeders and various cables such as cables and signal cables that carry radio frequency, sound or data.
In radio frequency systems, the antenna, usually on the antenna tower elevated above the ground, always a place where the best level of signal is. The same ideal place to click the radio frequency signal is also where the lightning increase is most likely to occur. The lightning is located at the highest point of such towers to "catch" most of the lightning surge, but part of the surge energy will find the way to electronic equipment.
current overvoltage available on the market include power protection devices and signal protection devices. 110 VAC volts (VAC) EQ with power evaluation can usually manage the voltage increase, causing the input voltage to increase to a maximum of 150 VAC. For all types of signals are to DISPOZice also protective devices for signal current. These include radio frequency surge devices as well as overvoltage protection devices for sound and data.
The prediction prediction is also important to maintain electronic and electrical equipment. The district designers must anticipate all possible increases in conditions to create reliable equipment. These transitions are able to overload the circuit components to the point of total or partial failure.
