Non-Intrusive Current monitoring (NIC) Unit Rowe Hankins Ltd. Non-Intrusive Current Monitors (NIC) assist wayside signalling and telecoms applications of Network Rail’s preventative maintenance programmes. The NIC units monitor operational and earth leakage currents of wayside critical signals and fixed electrical installations.

The NIC is a passive device that detects the current flowing in a signalling or telecoms systems cabling, with no effect on the signal or power supply of the system being monitored. The NIC can detect very small signalling, telecoms and/or earth leakage currents. They are normally installed as a key part of a local datalogging or SCADA RTU system connected to the regional operational control centre (ROC). The NIC offers the facility of a “volt-free trip contact”, that operates immediately on the detection of any current signals measured outside of their normal operational limits. The “trip”...
