Recloser principle

Pomanique's ZX-Series recloser are used in overhead lines and in substations. Like circuit-breakers they are capable of switching normal and fault currents. They are equipped with sensors and controller being the protection and control device. In case of a temporary line fault, they can trip and reclose up to four times, thus avoiding longer network interruptions.

Controller

The Microprocessor Based controller provide protection, control, monitoring, instrumentation and metering with integrated input and ou utput logic, data logging & fault reports.

Communication access to controller functionality is via electrical RS485 port for remote connection. Additional rear port options including RS232 port is available. The controller is mounted in the control cubicle. Along with the controlle,, this cubicle also contains the auxiliary power supply with batteries for uninterruptible power supply, electronic boards and circuit breakers. The controller contains a large number of protection functions (elements) which can be selected or deselected through the menu driven display.

Operating sequence

Reclose times are selectable. The operating sequence is defined by: OO - 1st rt - CO - 2nd rt - CO --3rd rt – CO .
