Description

Overview

  • Specially designed to reliably measure contact resistance of various Test Objects - Circuit Breakers, Isolators, Busbar joints, Welded joints etc., under the hostile electrostatic noise found in live EHV switch yards ensuring operator's safety and repeatability of results
  • Quick & simple tool to assess heat dissipation inside CB interrupter without opening it
  • Especially useful for resistance measurement of cables, graphite bars etc
  • Measures the mili-volt drop in presence of high induced charge environment of kilo-volts

Features

 

  • Powerful, truly continuous inbuilt 100A current source - no 'ON-OFF' duty cycle.
  • Flexibility to test objects with lower current ratings and higher resistances through the lower current ranges like 10A, 20A & 50A.
  • Direct display of micro-ohm value with out need of manual calculations.
  • Fool-proof connections and repeatability are ensured by specially designed proprietary biting type CK clamps.
  • Supplied with rugged calibrated test lead set suitable for 4 wire measurement.
  • No need to compensate lead resistance as Kelvin's Four wire measurement method is used.
  • Easy to use - self guided operation through interactive menu and keyboard.
  • Housed in rugged case enhancing transport worthiness.
