Capacitor Voltage Transformers
1.1 This Standard applies to capacitor voltage transformers (CVT) intended to be connected between line and ground, comprising essentially a capacitor divider and an electromagnetic unit inter-connected as shown diagramatically in Figure 1. The capacitor voltage transformer may or may not have provision for power line carrier coupling.
1.2 This Standard in applicable parts will also be valid for capacitor dividers used as coupling capacitors.
1.3 This Standard does not apply to field-adjusted capacitance potential devices, including bushing potential devices and out- of-phase potential devices.
