Why Current Transformer (CT) Pre-Testing Is Critical for Reliable Power System Performance
Current transformers play a critical role in protection and metering systems. If a CT isn’t performing as expected, it can impact relay operation, measurement accuracy, and ultimately the reliability of the entire electrical system. Pre-testing helps verify: – Correct polarity and ratio – Proper wiring and connections – Insulation integrity – Overall CT condition before […]
Reduce Transformer Failure Risk with Pre-Installation Bushing Testing
Never assume a new bushing is an acceptable bushing… Pre-installation testing can identify: • Elevated power factor / dielectric losses • Capacitance abnormalities or mismatches between phases • Shipping or handling damage • Manufacturing defects before they become field failures A few minutes of testing prior to installing and vacuum filling can save a lot […]
