Contact Resistance Meter Dealers in Pune

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.

• Brand Name: SCOPE
• Model Number: CRM 200B+

SCOPE introduces its next generation of hugely popular CRM series contact resistance meters,CRM200B+ in all new super light avatars, based on cutting edge ultra capacitor technology. CRM incorporates some state of the art hardware & smart software features making it a must have tool for testing & maintenance engineers.CRM directly measures micro-ohm values at 100 / 200 Amps DC under live EHV switchyard conditions quickly & accurately. CRM is specially designed to reliably measure micro-ohm contact resistances of circuit breakers,isolators, busbar joints, earth switch joints, welded joints etc., under the hostile electrostatic noise found in live EHV switchyards up-to 765 kV. SCOPE’s ability to make electronics work in such environment enables CRM to measure millivolts signal in the presence of kilovolts noise. CRM is equally suitable for MV / HV / EHV equipments and is very useful to Power Companies, Equipment Manufacturers, Testing & Commissioning Companies and Test Laboratories etc. Model CRM 200B+ having in-built 200 A current source make use of innovative technology that makes them the lightest 200 Amps micro-ohm meter available.
