IT-system In an IT network
the distribution system has no connection to earth at all, or it has only a high impedance connection. In such systems, an insulation monitoring device is used to monitor the impedance. An insulation monitoring device monitors the ungrounded system between an active phase conductor and earth. It is intended to give an alert (light and sound) or disconnect the power supply when the impedance between the two conductors drops below a set value, usually 50 kΩ.Isolated systems are used whenever a high reliability of the supply is needed, e.g. emergency lighting systems. Due to the fact that the energy released in case of an earth fault will not be suffient enough to trip an MCB or RCB a different protection device is to be used in unearthed systems. An insulation monitor constantly detects the insulation resistance to earth and releases a signal whenever the thresholds are passed. Insulation monitoring relays are the only technical solution to detect an earth fault in an unearthed system. ABB’s offer at a glance – Modular set up – 3 products for AC and DC systems – Direct connection to 690 V AC and 1000 V DC systems with the coupling module – Frequency rating 15-400 Hz – Interrupted wire monitoring – Incorrect setting monitoring – Safety on board by implemented system test after start-up – Reset and test possibility at the front face or by control contact – New prognostic measuring principle
Additional monitoring functions
CM-IWS.1 and CM-IWN.1 – When interrupted wire monitoring is activated, the CM-IWN.1 automatically monitors the network/measuring circuit connections L+ and L- when the system starts up. This can be repeated at any time by activating the test function. CM-IWN.1 and CM-IWS.1 cyclically monitor the measuring circuit connections and KE for wire interruption. In case of a wire interruption in one of the connections, the output relays switch to the fault state. – In addition, the unearthed AC-, DC- or AC/DC system is monitored for inadmissible leakage capacitance. If the system leakage capacitance is too high, the output relay switches or the output relays switch to the fault state. – Also incorrect settings that could cause a faulty function of the device are monitored. When the device detects such an incorrect setting, the output relay switches or the output relays switch to the fault state. – Once the control supply voltage has been applied the insulation monitoring relay runs through a system test routine. The system is diagnosed and the settings are tested. If no internal or external faults are found after this test routine is completed, the output relays switch into the operational state. – By pressing the front-face combined test/reset button a system test routine is executed. The output relays switch to the fault state as long as the test function is activated, the control contact S1-S3 is closed or the test functions are processed.
