Non-Intrusive Current Transducers for
Industrial and Rail applications
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.
