SF6 Gas Insulated Vacuum Recloser
The SF6 gas insulated automatic recloser is designed for a use on overheaddistribution lines as well as distribution substation applications.
FUNCTION
- Fault detection & protection.
- Control & status monitoring
- Measurements(current, voltage, power factor, frequency, power, energy, counter)
- Recording(events,fault current waveforms, data logging)
- Safety devices(low pressure interlocking, pressurerelief, locking)
ADVANTAGES
- The magnetic actuator provides highly efficient, reliable performance while consuming very little energy.
- The controller is a microprocessor based controller that provides the protection, data logging and communications function.
