SRI3/I2 INJ - Industrial insulation fault locator controller - injector - 6 Din modules The SRI3/I2 INJ insulation monitor allows you to continuously monitor the status of networks with neutral isolated from earth (IT systems). The instruments are able to detect insulation defects due to the resistive component, even in the presence of parasitic DC voltages. The tools offer two differentiated reporting thresholds (Alarm and Fault). To carry out the fault finding procedure in the IT network, SRI3/I2INJ must be combined with at least one I2FL12 or I2FL18 fault finding expansion. Localization is made possible thanks to special FL series toroids (one for each departure to be controlled). When the insulation resistance of the system falls below the set threshold, the device will start the fault locator function. At the end of the search, on the display of the I2FL12 or I2FL18 expansion, the drawing of which or which outputs are responsible for the decrease in the insulation level will appear. For the fault localization function, a current is applied (settable from setup to 2mA, 4mA or 6mA) in relation to the type of system to be monitored (compliance with IEC61557-9 annex A). control with variable frequency signal injection network to control: AC/DC ≤500 Vcc/Vca – DC ≤700Vcc 2 fault intervention thresholds + alarm Ran adjustment: 5 KΩ ÷ 2 MΩ display Mains voltage display with over/under threshold setting 3 independent NO-C-NC contacts password protection setup
