Digital Transformer Ratiometer Model 8510


Features

  • Ratio Testing: PT/VT from 0.8000:1 to 8000:1 and CT from 0.8000 to 1000.0 (Auto-Ranging)
  • Tests performed by exciting the primary and reading the secondary; provides safer conditions for the operator on step-down transformers
  • Continuity test indicates open or loose (high resistance) terminal connections
  • DC test mode eliminates errors due to magnetic build up
  • Stores up to 10 primary/secondary nameplate voltages to use in comparing test results
  • Displays ratio, test current, winding polarity, and deviation from nameplate voltage or ratio
  • Stores up to 10,000 test results
  • DataView® software included which allows configuring the instrument, downloading stored measurements and printing of test results in a report format
  • Display warns of incorrect lead connection, reverse polarity, open and short circuits
