IRDH265-4 BENDER A-ISOMETER Insulation Monitoring Device for IT AC systems

Product Details

The fundamental functions:

For IT AC systems, for IT AC systems with galvanically connected rectifiers and IT DC systems (isolated power)

Extended voltage range via coupling devices

Automatic adaptation to the existing system leakage capacitance

AMP measuring principle

Two adjustable response ranges

LCD display

RS-485 interface

Connection monitoring

Automatic self test

Product description

The IRDH265 monitor the insulation resistance of IT3(N)AC, AC/DC and DC systems. The AC systems may include extensive DC supplied loads (e.g. rectifiers, converters, thyristor-controlled DC drives, see 2.3). The devices automatically adjust to the system leakage capacitance.

Coupling devices are available to extend the voltage range. The IRDH265 ISOMETER is fitted into a standard plastic casing suitable for DIN rail mounting according to DIN EN 50022 or for screw mounting.

Functional description

Both ISOMETER are connected between the unearthed system and the equipotential bonding conductor (PE). The setting of the response values and other parameters can be carried out via the function keys. The parameters are indicated on the LC display and are stored in a non-volatile memory (EEPROM) after setting.

A pulsating AC measuring voltage is superimposed on the system (AMP measuring principle). The measuring pulse consists of positive and negative pulses of the same amplitude. The period depends on the respective leakage capacitances and the insulation resistance of the system to be monitored. An insulation fault between system and earth closes the measuring circuit. An electronic evaluation circuit calculates the insulation resistance which is indicated on a LC display or an external ohmmeter after the response time.
