Automatic Oil Tester / Calibration Facility..
FEATURES
- Safety interlock on high voltage test chamber & zero start.
- The sets are available with printer &/or RS 232 interface.
- Equipment to enable easy, accurate & safe measurements
- Micro controller controlled, saves operator's time.
- Recall of individual tests including breakdown voltages, averages & the test number, all displayed digitally.
- Emergency exit allows the operator to quit the process.
APPLICATION
Theses tester sets are used for determining the di-electric BDV of insulating oils, both new and in-service from transformers, switchgear and other electrical equipments.
