Small Signal Current Monitoring (NIC)
Applications
Non-Intrusive Monitoring
To assist wayside applications of Network Rail’s preventative maintenance program, by monitoring currents in rail signalling problems equipment.
How does it work?
The NIC (Non-Intrusive Current Monitor) is used as part of the preventative maintenance systems on wayside applications.
The DIN rail mounted NIC units are designed to measure AC/DC currents up to +/-600mA when the primary cable is passed through the hole on the side of the unit.​
The NIC provides a scaled 4-20mA current output to the end users’ equipment. This may take the form of a data logger which stores the raw data that can then be remotely downloaded for analysis.
Data analysis allows for trends to be visualised for equipment that might show degradation , i.e. current variations outside normal limit, thus allowing targeted maintenance to be carried out before actual failure.
