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)
