Portable Insulation Monitoring System
EKRA-IMS-PIMS

At facilities with no stationary insulation monitoring systems, portable PIMS kit can be temporarily connected to check the insulation level of DC network

In case of detection of insulation resistance reduction of the pole, the faulty bay can be manually detected by measuring the resistance of each bay one by one using PIM device (PIM device is included in the scope of supply)

Front view

PIMS has a sealed impact-resistant plastic case and includes the following components:

relay for pole insulation resistance monitoring in DC network, IMR-02 type
portable insulation fault detector in DC network
wires for connection

PIMS connection scheme

Patent for invention

Portable insulation monitoring system EKRA-IMS-PIMS is protected with a patent for the invention

No maloperation of relay protection devices

Do not cause maloperation of relay protection devices due to the low level of voltage imbalance

Universal use and convenience

Detection of asymmetrical and symmetrical reduction of insulation level. All measurements are carried out without disconnecting consumers from the network. May be used at several facilities one by one

Compatibility

Compatible with equivalent standard T-bridge insulation monitoring circuit
