GENERAL INFORMATION
What is Pulse Voltage?
Impulse Voltage; It is a single-pole, high-frequency voltage type that rapidly rises to a peak value and then quickly drops to zero.
Impulse Voltage Test
Lightning impact tests are carried out in order to determine to what extent high voltage devices are affected by lightning. In order to carry out these tests, impulse voltages are produced in the laboratory environment. In other words, impulse voltage is a type of voltage created in a laboratory environment to simulate high voltage.
