EM TEST VSS 500N6 Voltage Surge Generator
Description
VSS 500N6 Voltage Surge Generator with Constant Pulse Energy up to 6.6 kV
EM TEST VSS 500N6 Voltage Surge Generator is designed as per IEC 60255-5 meeting the requirement to maintain constant pulse energy at different test levels as specified by the standard.
The VSS 500N6 generates high voltage transients with a source impedance of 500ohm for transient overvoltage tests on “Protection Relays”. The output voltage ranges up to 6.6kV, covering for tests levels 1 to 5.
The IEC 60255-5 standard requires a fixed energy of 0.5J at each test level which corresponds to the no-load waveshape per IEC 61180-1. The test generator itself follows the specifications as per IEC 61180-1 and covers the predefined voltage levels corresponding to the most used test voltages used for relay testing.
