Instrument Transformer Test Set-UPS
Instrument Transformer Test Set-UPS
Sev Electrical Equipments Pvt Ltd has introduced an Instrument Transformer Test Set-UPS to carry out the accuracy test of instrument transformers like current transformers and potential transformers as per relevant IS/BS specifications and other international specifications.
Principle:
- The CT/PT test bridges consists of magnetic balance circuit, which is susceptible to the minutest magnetic unbalance
- The method is a comparison method, which compares "under test transformer" with "standard/reference transformer"
- Due to error in transformer the "magnetic unbalance" is set up and same is corrected by the proper injection of calibrated magnetic effects
- These corrective injected magnetic effects are proportional to "angle errors" and "ratios errors"
- The calibrated dials "indicate corrective injection" and thus direct indication of "phase angle error" and "ratio error is obtained".
- The current/voltage at which test is carried out is indicated on digital meters as "percentage for CT test bridge" or volts (secondary) for PT test bridge
- Calibrated dials have selection as + zone or - zone so as to have maximum scale length utilisation
- Sensitivity control for null detector
- Polarity detection of "transformer under test" by `LED' with 'polarity' position on "multiplier switch".
