Description

Overview

  • Designed to measure DC winding resistance of highly inductive test objects - Transformers, Generators, Motors etc. for field testing as well as for factory testing
  • Designed to work reliably under live EHV switchyard conditions ensuring operator's safety and repeatability of results
  • Winding Resistance Meter designed for large transformers up to 315MVA
  • Quick stabilization of reading even on large test objects by deploying high open circuit voltage
  • Quick & simple tool to check the condition of OLTC - discontinuity during tap change, if any
  • Direct display of Resistance values
  • Available for continuous testing - powerful, truly continuous DC source with excellent heat management through forced cooling
  • Total instrument and human safety ensured through automatic & quick back-emf discharge after test completion
  • Discharge possible through either voltage or current lead in case of accidental lead disconnection - operator risk is minimized

Features

 

  • Injects test current of 10A DC for measuring winding resistance as high as 2Ω
  • Has two voltage input (resistance) channels and one test current channel
  • Saves down time, measurement of resistance of 2 windings simultaneously
  • In-built stable DC source and direct display of resistance value
    • Single compact instrument
    • No need to spend time in bridge balancing
    • No need of manual calculation
  • Backlit graphic LCD with a user-friendly menu sets up the instrument for the test
  • Configuration
    • Permits enable / disable of measuring channels
    • Test setup: Current range selection, resistance range selection
  • Easy to use - self guided operation through interactive menu and keyboard
  • No need to compensate lead resistance as Kelvin's Four wire measurement method is used
  • Housed in rugged case enhancing transport-worthiness
