Insulation Monitoring

Description

Insulation monitoring devices continuously monitor the insulation resistance of IT systems (unearthed systems) and issue an alarm if the value falls below a response value.

To obtain a measurement, the device has to be connected between the IT system and the protective earth conductor (PE). A measuring current is superimposed onto the system which is detected and evaluated by a measuring circuit. Insulation monitoring devices detect deteriorations of the insulation level at an early stage and in a reliable way.

 

Examples of Application:

Power supplies of complex production processes.

Control circuits in safety applications.

Variable-speed drives in rolling mills, conveyor systems.

Mobile power generators.

Traffic signaling systems.

Offline loads (pumps, motors)

Medical locations.

Control circuits in power plants and substation.

Power supplies on ships.

Photovoltaic systems and much more.
