VT and CVT may look familiar, but are you sure you fully understand them? ⚡ In a substation, VTs/CVTs are not just for "stepping down" voltage; they are critical signal sources for metering, protection, SCADA, and PLC systems.

- Reversed polarity?
- Choosing the wrong ratio or confusing a VT with a CT?
