CRM 200B

CRM 200B directly measures micro-ohm values at 200 Amps DC under live switchyard conditions. CRM 200B is specially designed to reliably measure contact resistance of circuit breakers, isolators, busbar joints, welded joints etc., under the hostile electrostatic noise found in live EHV switchyards upto 765 kV.

Inbuilt rechargeable battery tremendously enhances utility as AC supply connectivity is not required.CRM 200B operates on a rechargeable battery as well as Mains supply. It has a built-in constant current source, a precision instrumentation amplifier, digital readout and control logic.

A pulse of 200A DC is passed through the test object and voltage drop is sensed using the classical Kelvin’s 4 wire method to measure contact resistance. Both test current and resistance value are displayed on LCD.

Features

 

  • A radically new design makes CRM the lightest available contact resistance meter.
  • Battery as wall as Mains operated.
  • Direct display of micro-ohm value does away with manual calculations.
  • Fool-proof connections and repeatability are ensured by SCOPE’s specially designed proprietory Ck clamps.
  • Supplied with rugged calibrated test lead set suitable for 4 wire measurement.
  • Additional range of 20 mΩ is provided.

MD 5060x

The Megabras MD-5060x is a smart, microprocessor-controlled, 5kV insulation tester and analyzer. Besides the conventional measurement of insulation resistances up to 5 TW, its advanced features allow to automatically measure both the Polarization Index and Dielectric Absorption Index, thus significantly simplifying testing of transformers.

This insulation tester is a portable, battery-powered equipment. Test voltage may be chosen from 500V to 5 kV in 100 dddV increments. Due to its measurement principle (actual voltage and current readings) the accuracy of resistance measurement is not affected by any test voltage error. Nevertheless, the High-Voltage generator is electronically stabilized with a better than 2% accuracy in open-circuit condition and for any normal operation battery voltage.

The MD-5060x is powered using a rechargeable battery and has an automatic charger that may be connected to 100 - 240V mains supply. The cabinet is strong and lightweight, easy to carry, impact-resistant and suitable to be used under severe weather conditions. Thus the megohmmeter supplies very reliable and accurate measurements both in laboratory and out in the field.
