Impact of Frequency on Voltage Transformers: Testing at 50Hz vs. 60Hz

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…
