High Voltage Online (Live Wire) Testing Solution provides the ratio error of the CT/PT Kit, without going for a shut down of the industry. HV Live wire screening method is easy and time-efficient. Besides the waveform & harmonics analysis, CT saturation error or any other error can be identified easily.
Challenges With Existing Testing System
- Industries are reluctant & resistive to outages/shutdowns, as it affects their operations for the duration of the test.
- In many cases HV Consumers’ CTPT is tested only once in their lifetime, at the time of installation, when its guaranteed to be healthy. Over the period of time either tampering/ageing may cause CTs to deteriorate which affects the revenue of Periodic annual testing of CT’s tend to be compromised due to the inconveniences that it involves.
- Distribution Utility needs to put in a lot of background work- documentation, follow-ups & arrangements for such 11kV/33kV CTPT Testing, because the industry needs to give its concurrence for a shutdown.
- Offline/with-outage CT/PT Testing may take 2 to 5 hours or more in certain cases, which results in loss of Revenue & man-hours of Distribution Utility as well as Industries.
Live wire testing addresses all the above challenges of the existing system.
HV Consumers CT/PT Testing is carried out Online/Live Wire without shutdown of the industry. It will certify healthiness and find out irregularities if any at the consumer end.
