Multifunction Electrical Installations Meter

MPI-502 - Sonel S.A.

Short circuit loop parameters measurements:
measurements of short circuit loop impedance in networks with rated voltage: 220/380 V, *230 V/400 V, 240/415 V and frequency 45...65 Hz,
*measurements of short circuit loop impedance with current 15 mA without tripping the circuit breaker.

Testing the RCD breakers of AC, A types:
*testing of prompt, short-delay (general) and selective RCDs for the rated current values 10, 30, 100, 300, 500 mA,
*IA measurement
*RE and UB measurement without tripping the circuit breaker,
*extended RCD test function AUTO, with measurement of ZL-PE with current 15 mA - measurement of IA and tA during one RCD tripping.

Detection of the replacement L and N in the socket and automatic conversion in the meter.

Low voltage resistance measurements of protective circuits and junctions:
*measurement of resistance with ±200 mA current
*calibration of test leads - possibility of using any length of test leads,
*low current resistance measurement with accoustic signalling
