Why PT Testing Is Important

PT testing is vital for the accurate and safe measurement of high voltages in electrical systems. Potential Transformers step down high voltage to safer levels (like 110V or 120V) for metering and protection. Inaccurate PTs can lead to faulty readings, system faults, or even equipment failure.

In this video, we cover:
