ENHANCED TECHNOLOGY
When a fault current is detected, the recloser operates the pre-set full protection sequence again.
EVR is powered by AC 110/220V low voltage distribution line source without an additional
transformer and is designed to consume low energy to operate reclosing and remote control. Thus
EVR does not need any extra cost for installation of additional transformer, in case, low voltage
source by utility is available.
In case that low voltage power source is not available, the recloser is fitted with an auxiliary
voltage transformer to supply auxiliary power to the control cubicle.
During open and close operations, the relay sends the pulse type current to the open and close coils,
and the magnetic force is induced by those coils and moves the plunger of the magnetic actuator.
This driving force is transferred to the vacuum interrupter, which makes contact point tripped or
closed. During trip and close operations, arc is produced and rapidly extinguished in the vacuum
interrupter. The relay setting in control circuit can be modified at the control panel, a PC or
remotely controlled communication method. For more details, refer to EVRC2A manual.
