Product Description

General
 The electric sectionalizer has been developed for use on overhead distribution lines to improve reliability and service continuity. It enhances the protection of the distribution systemin a simple, economical way which is free from maintenance and spares. Statistics indicate that 70% .90% of fuse cutout operations are in response to transient faults. The electronic sectionalizer enables customers to better manage these types of transient faults, It is designed to substitute a fuse cutout, ensuring effective isolation only in the event of a  93sustained fault, It remains unresponsive to transient faults. The sectionalizer is a selfcontained device, designed to be used in a coordinated overcurrent protection scheme with automatic reclosers.
    This sectionalizer uses micro-computer and operating trip mechanism and does not require external auxiliary supply.And it is designed to withstand the mechanical forces generated by high fault currents. Its design also caters for the durability needed with repetitive hook stick closing in harsh outdoor environments.
    The electronic sectionalizer incorporates electronic logic and trip circuits which are controlled and powered by a dual core current transformer mounted on the copper conductive tube.The current transformer is mounted externally to the conductive tube and encapsulated in a durable weatherproof epoxy.
    The electronic circuit provides the necessary intelligence for counting recloser tripping operations and provokes the opening of the sectionalizer at the appropriate time. The electronic circuit is encapsulated with epoxy, within the environmentally sealed conductive tube. The tube acts as a faraday cage, protecting the electronic circuit from the influence of magnetic fields.
    Tripping is achieved when a solenoid located in the lower half of the conductive tube is energized and the trip arm is released enabling the hinged trunnion to collapse.

Working principle
The current transformer built in the cutout sectionalizer can detect the current of the main circuit and send the output to the electronic control for digital handling. When a fault occurs,the upstream recloser (or circuit breaker) opens, the circuit loses voltage and the current is lower than 300mA, the electronic controller can remember this opening time as a "count" . As it accumulate the presetting number (1 to 4), the sectionalizer will automatic trips within180ms of fault interruption to isolate fault. Then the upstream recloser (or circuitbreaker) closes to restore power supply to the healthy section of the system to limit outage scope and protect the main feeder in service. If the fault is temporary and is cleared before the sectionalizer counter reaches the presetting number, the sectionalizer remains closed and resets to its original state after its reset time expires.
