Compact and portable. Contact Resistance Meter is meant for measurement of resistance of bus bar joints, male-female contacts of isolators, SF-6 Breaker contacts, GTS breaker contacts etc. of the sub-stations. The measurement of contact resistance is done by applying a DC current of 0-100 Amps. and measuring the voltage drop across the contacts. An ammeter and a millivoltmeter (Micro-ohmmeter) are provided measuring the current and resistance. A lamp indicates the AC supply position. A variac is provided for adjusting the output current from 0 to 100 amps. Fuse for protection against overload is incorporated. CRM Range: 0.1 micro-ohm to 19999 micro-ohm in two ranges.Input: 240 V ±10%, 50 Hz. ±5%.Output: 0-100 Amps., DC, continuously variable.

measurement voltage any in the range of: 50…10000 V (50…1000 V at 10 V and 1…10 kV at 25 V), continuous indication of measured insulation resistance or leakage current, automatic discharge of measured object capacitance voltage after the end of insulation resistance measurement, acoustic signaling of 5 seconds intervals to facilitate capturing time characteristics, metered T1, T2 and T3 test times for measuring one or two absorption coefficients from the range of 1…600 s, polarization index (PI), absorption coefficients Ab1, Ab2 and dielectric absorption ratio (DAR) measurement.

Static contact resistance measurements are essential to check the health and functionality of the main contacts of the circuit breaker. If the contacts are not in a good condition there can be arcing and single phasing. Due to oxide depositions and absorption of moisture, the contact resistance often increases. This leads to I2R losses in the contacts due to hot-spotting when the circuit breaker is closed. MVT Contact Resistance Meter uses Kelvin’s 4-wire method to accurately measure the static resistance of the circuit breaker main contacts. It has a built-in continuous DC source of up to 200A and performs resistance measurements in the micro-ohm range by measuring the millivolt drop in the contacts. MVT is compact and portable, which allows it to be taken on-site for field testing requirements. It is suitable for measuring the contact resistances of vacuum circuit breakers, high voltage circuit breakers, extra high voltage circuit breakers, isolatorsdisconnectors, bus bars, and many other components used in power transmission and distribution.
