Voltage transformers (VTs) are essential in electrical power systems, ensuring accurate voltage measurements and system protection. But here’s the catch—these transformers behave differently depending on frequency. Testing a voltage transformer at 50Hz versus 60Hz isn’t just about a simple number change. The shift in frequency affects magnetic flux, impedance, losses, resonance, and accuracy. Ignoring these…
