1.范围1。1本标准适用于拟连接在线路和地面之间的电容式电压互感器（CVT），基本上包括一个电容分压器和一个相互连接的电磁单元，如图1所示。电容式电压互感器可能有电力线载波耦合的规定，也可能没有。1.2本标准适用于用作耦合电容器的电容分压器。1.3本标准不适用于现场调整电容电位装置，包括套管电位装置和异相电位装置。

1. Scope1.1This 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.1.2This Standard in applicable parts will also be valid for capacitor dividers used as coupling capacitors.1.3This Standard does not apply to field-adjusted capacitance potential devices, including bushing potential devices and out- of-phase potential devices.
