Electrical Cable grounding is important when it is used in instrumentation or automation system. In automation system special cable carry sensor/plc signals in 4-20 ma range. Thus Leakage current from external source will create noise or even damage the sensor / PLC with fault current.
This is an instruction for grounding of shielded standard cables and cables equipped with inner shield. The Instruction can be used on Ship Power and Power Plant solutions.
- Outer shield is always grounded in both ends of cable using EMC cable glands .
- Inner shield (if exist) is connected only in one end.
