American National Standard for Requirements for Power-Line Carrier Coupling Capacitors and Coupling Capacitor Voltage Transformers (CCVT)
美国电力线载波耦合电容器和耦合电容电压互感器(CCVT)要求国家标准
ANSI/NEMA C93.1-1999 applies to capacitors for coupling power-line carriers and for reducing rate of rise of breaker transient recovery voltage, and to CCVT for connection to a high-voltage power circuit, between line and ground, to supply a low voltage for measurement, control and protective functions.
