On-load Tap Changer

LTC-27

UDEY On-Load tap changer(OLTC) mainly measures transition time, transition resistances, transition waveform. This is an important tester to check the transformer circuit.

Advantages of LTC-27:

  • Self contained, light and portable single unit
  • Built in precision constant current source with protection circuit
  • Tests with or without winding
  • Built-in printer
  • Light weight – 5 kgs.

Feature

  • Embedded PC-104 industrial personal computer.
  • 6-channel high speed synchronized data sampling.
  • Saves over 10,000 groups of test data on 1G storage.
  • T9 input available for figures, alphabets & symbols.
  • Store data as station name, serial no & tap position.

Safety Features

  • Protection circuit
  • Earth terminal for connecting external earth
  • Sheathed output sockets
  • Mains socket with built-in fuse
