BS EN 61334-3-22:2001 Distribution automation using distriubution line carrier systems. Mains signalling requirements. MV phase to earth and screen to earth coupling devices
This part of IEC 61334 is applicable to MV phase-to-earth capacitive and screen-to-earth intrusive inductive coupling devices for medium voltage (MV) distribution line carrier (DLC) systems. Non-intrusive inductive coupling devices are not within the scope of this standard.
The coupling device ensures
a) the efficient transmission/reception of carrier-frequency signals between the DLC transceiver and the power line;
b) the safety of personnel and the protection of the low-voltage parts of the installation against the effects of the power-frequency voltage and transient overvoltages.
The object of this part of IEC 61334 is to establish definitions, requirements, methods of testing and rated values for phase-to-earth capacitive and screen-to-earth intrusive inductive coupling devices to be used in MV-DLC systems.
