Test & Measurement
-
NIF (Dutch Instrument Factory, later Nieaf-Smitt) started in 1900 as one of the first organizations in the world with the design and production of instruments for electrical values. The portfolio of test tools, digital multimeters, current clamps, device testers, installation testers and power analyzers is characterized by quality and reliability.

Protection Relays
-
Electrical protection relays for high voltage & high current protection offer protection in traction equipment as well as railway infastructure. Protection relays are used for applications like catenary voltage, short circuit, overload and ground fault detection in traction power electronics or railway substations.

Auto Reclose and Sync Check
-
Operating records for overhead power lines reveal that most faults are of a transient nature (e.g. lightning induced) & that service interruptions may be minimized by use of automatic reclosing of circuit breakers. An automatic reclosure of the circuit breaker, after the fault clears, provides improved service continuity & system stability. The 1B230 Series Reclose Relay provides for single or double shot automatic reclosing of circuit breakers, following interruption of supply due to a fault in the system.

Latching Relays
-
A latching relay is a two-position electrically-actuated switch. It maintains either contact position indefinitely without power applied to the coil. It is controlled by two momentary-acting switches or sensors, one that 'sets' the relay, and the other 'resets' the relay. The latching relay maintains its position after the actuating switch has been released, so it performs a basic memory function.

Industrial Plug-in Power Relays
-
The unique D-series power relay concept and the miniature C-series relays are specifically designed for heavy-duty applications, power-utilities, petrochemical industries, and mining. High DC breaking capacity and inductive load switching offer long electrical life and low life-cycle costs. The Solve-All™ relay application concept offers ultimate flexibility to design and supply tailor made D-series power relay products. Today the D-series power relays are used in its millions across the world.

Automatic Power Control system
-
The Automatic Power Control system cuts the incoming power supply to a traction unit for short periods. This is required where power supplied from one part of a power distribution system in separated from another by a neutral section. Its fitment prevents damage to the power distribution system or the vehicle.

Product
Pilot Wire
-
The concept is based on the need to improve the performance of existing pilot wire protection schemes by increasing reliability & availability as well as adding an over current guard function. This can be achieved at considerably lower cost than the replacement of the existing proven protection relays & change over to a fibre optic communication channel.
