SRI3/H2FL6 - Fault Locator 6 starts - 6 Din modules Ran: 50 KΩ ÷ 1MΩ Developed for medical and hospital environments, the SRI3/H2FL6RS485 insulation controller allows you to continuously monitor the status of LV networks with neutral isolated from earth (IT-M systems). The controller is able to detect insulation defects due to the resistive component even in the presence of parasitic DC voltages. The instrument signals the first earth fault on the display indicating both the value in KΩ of the leakage and the maximum fault current that could flow through the resistive leakage itself. The device is also able to monitor the temperature of the isolation transformer, current overload and over/under voltage. All alarms detected by the insulation controller are signaled visually on the display and visually/acoustically on the appropriate PSR3 remote repetition panel. Fault localization occurs via TD15 model toroids installed one for each start-up to be checked. When an insulation fault appears, SRI3/H2FL6 starts a search procedure at the end of which it signals on the display which start-up has an insulation fault. SRI3/H2FL6RS485 can be equipped with a maximum of 6 TD15 model toroids (15mm diameter split toroid).
