voltage transformer definition
voltage transformer or “VT” means a transformer for use with meters and/or protection devices in which voltage across the secondary terminals is, within prescribed area limits, proportional to and in phase with the voltage across the primary terminals.
voltage transformer or "VT" means a transformer intended for metering, protective, or control purposes and designed to have its primary winding connected either between the primary conductors to be measured or between a conductor and ground. A voltage transformer normally reduces voltage magnitudes to levels which can be handled by control, protection, and metering equipment. The historic term for a VT is potential transformer.
voltage transformer means an instrument transformer in which the secondary voltage, in normal conditions of use, is substantially proportional to the primary voltage and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections.
