IEEE C93.3-2017 IEEE Standard Requirements for Power-Line Carrier Line Traps (30 kHz to 500 kHz)

IEEE C93.3-2017 IEEE Стандартные требования к Power-Line Carrier заградители (30 кГц до 500 кГц)

This standard applies to a line trap inserted into a power line to provide a high impedance at power line carrier frequencies (30 kHz to 500 kHz). The purpose is to isolate the carrier signal from system impedance changes due to faults or switching behind the point of insertion, and to guide the signal in the proper direction. The standard covers line traps in which the main coil is designed as a single-phase, air-cooled inductor of the dry type.
