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
