A. AREAS OF USAGE

  • Three phase primary current injection
  • Testing of protection relays
  • Thermal and magnetic device testing
  • Temperature rise test and trip test of circuit breakers and junction point
  • Each phase can be adjusted independently by motor on demand

B. TECHNICAL FEATURES

C. OPERATING INSTRUCTIONS


Depending on the test to be performed, turn the position switch (example : 3x2,5 V 4000 A or 3x400 V 45 A) to the proper selection. Install the intermediate connections with maximum 2A/mm2 current density cables which have equal cross-sections and equal lenght. If any gap is left between current carrying cables, because of the effect of inductance, maximum current can not be reached. The best solution is to have a touch between current carrying cables. Thermometer probes must be connected to the measurement points with tongs or tapes.
