Feature:
- A smart and reliable solution designed for easy mainte nance and future upgradeabili ty.
- Offers flexible phase and ground overcurrent protection for the main feeder, and provides power quality monitoring and metering.
- Contains modular compo nents (control module, power supply module, cabinet, heater, and MCCB) that are easy to maintain and service.
- The control panel of the recloser is interactive, with programmable soft keys and large interface push-buttons to allow for single push activation of commonly used control functions. Its LED indicators show the current status of the recloser.
- The control is password protected and housed in a weatherproof cabinet that can be padlocked.
- With cables connections to the recloser, the control can also be housed separately from the recloser.
- Maximum/minimum phase and ground demand current values.
- Overfrequency/ Underfrequency Protection.
- Overvoltage/ Undervoltage Protection.
- Simulator to test metering and protection function with virtual current and voltage injection.
- An impedance-based fault locator to calculate the distance by impedance calculation.
- Loss of phase protection trips the recloser if phase-earth voltage on one or two phases falls below a defined voltage threshold.
- Smart Phone application for metering, data access, operation and positioning.
- Sync-check capability based on source side ane load side PT to qualify close signal to the mechanism when enabled via the sync check settings.
- Duty cycle monitor to measure and record duty in non-volatile memory.
