Neel Systems

Advantages

	The superintend supervising system helps detect faults & generates alarm in case of wiring errors, neutral to groung faults, connection of defective devices, insulation damage, leakage current insufficient to blow a fuse or trip a circuit breaker.
	Can eliminate shock hazards in hospital & health care applications caused due to large voltage differences between ground potential of separate grounding points.
	Can prevent HF disturbances & transients generated by neutral & ground being connected together.Thus causing malfunction / break down of computers, CNC M/C & other digital Equipment.
	Can prevent induction of strong magnetic peak fields, harmful in recording studios & areas where accurate magnetic measurements are desired.

Applications

Data processing facilities, Health care facilities, Office buildings & hotels, Automated industrial plants, Telecommunication centres, Fire hazard areas, Monitoring insulations of cables and High power motors.
