Measuring and Monitoring Relays

Description

Various measuring and monitoring relays are available for the purpose of monitoring electrical quantities. In addition to over-voltage, under-voltage, frequency, unbalance, phase sequence, phase failure and loop monitoring, special solutions for specific applications are also possible: extended temperature ranges, sector-specific standards, compact design, country-specific profiles.

 

Examples of Application:

Loop monitoring for motors

Loop monitoring for PE conductor interruptions in electrical installations

Monitoring of earthing systems

Current consumption of motors, such as pumps, elevators, cranes

Monitoring of emergency lighting

Monitoring of screw conveyors, e.g. in sewage plants

Monitoring of voltage-sensitive electrical installations

Switching on and switching off function at a certain voltage level

Monitoring of stand-by and emergency supply systems

Supply voltage monitoring of portable equipment

Protection of three-phase motors against phase failure and phase sequence

Transformer protection by detection of non-symmetrical loading

Main decoupling electricity generating systems(NS protecting)
