Test System for Motor Protection Circuit Breaker (MPCB)

This is a LabVIEW – PC based Test System for Motor Protection Circuit Breakers. This tests 30 MPCBs simultaneously. A Motor Protection Circuit Breaker is supposed to trip when there is overcurrent. This test equipment tests the MPCB for Overload Current Trip.

MPCB

  • Variable Current Source : 0.1A to 50A With Following Taps on secondary of power transformer 60V/50A , 90V/15A, 220V/4A, 400V/2A & 900V/1A. The Selection of output taps with contactors.
  • The Current will be kept constant through out the test with the help of Servo Controlled Closest loop system.
  • Each Station will have bypass arrangement with contactors.
  • CT With 0.2A, 0.5A, 1A, 2A, 5A, 10A, 20A & 50A taps to get accurate current measurement, The selection of CT tap will be with contactors.
  • The selection of CT Tap, Output Voltage will be through PC, which will get selected with MPCB rating.
  • Indication of Current, trip time of such station on PC Screen.
  • Input Supply 1Ph. 230VAC 50Hz 16A max
  • Connection of MPCB will be manual by operator. We will provide terminals for MPCB connections & standard Din rail channel for mounting MPCB for testing.
  • LabVIEW based software with SCR’s Ethernet based communication system to control the test parameters & to generate test report in any one approved format.
  • HP / Dell / Lenovo make PC with Windows OS
