AC Current Amplifiers

AC switching Current Amplifiers

frequency range of 45Hz - 100Hz

output power of up to 5kVA at cos Phi 0 (ind) -1 - 0 (cap)



Typical applications for these amplifiers include:

  • Testing thermal and magnetic trip characteristics of circuit breakers
  • Testing of trip characteristics of fuses
  • Calibration and testing of ammeters, powermeters etc.
  • Complex multiphase mains simulation systems of line currents and line voltages across multiple phases (e.g. for testing of power line protection devices such as Distance Protection Relays for the electricity supply industry)
