What is a VSA recloser?
What is a VSA recloser?
Recloser. Eaton’s Cooper Power series VSA-group three-phase reclosers feature vacuum interruption with air insulation and low-voltage motor operation. These reclosers are designed for circuit protection on systems operating through 14.4 kV.
What is a nova recloser?
Eaton’s Cooper Power series NOVA recloser is a three-phase, vacuum-interrupting recloser that successfully combines four patented technologies: cycloaliphatic-epoxy encapsulation, high-performance vacuum interrupter, dependable lower power mechanism and an automated microprocessor recloser control.
What is a viper recloser?
G&W Electric’s ViperĀ®-ST independent pole operated (IPO) recloser combines the time proven reliability of electronically controlled, vacuum fault interrupters with the maintenance-free benefits of a solid dielectric insulated device.
Whats the difference between a breaker and a recloser?
Circuit breakers are designed to allow maintenance, whether of the operating mechanism itself, or for replacement of vacuum interrupters. Reclosers, generally, are not designed to allow maintenance by the user, and require return to the manufacturer if any internal maintenance is needed.
How does a recloser work?
How does a recloser operate? The recloser senses when trouble occurs and automatically shuts off the power. An instant later (the length of time may be noticeable only as a lightbulb flicker), the recloser turns the power back on, but if the trouble is still present, it shuts it off again.
What is the function of a recloser?
A recloser is an automatic, high-voltage electric switch. Like a circuit breaker on household electric lines, it shuts off electric power when trouble occurs, such as a short circuit.
What is a viper St?
Viper-ST is an independent pole operated (IPO) recloser which combines the time-proven reliability of electronically controlled, vacuum fault interrupters with the maintenance- free benefits of a solid-dielectric insulated device.
What is the difference between a recloser and a breaker?
Where are reclosers located?
Reclosers are small circuit breakers located at the top of distribution poles and are typically used on very long distribution feeders. Their function is to isolate a section of the feeder in fault or overload conditions and thereby minimize the number of customers without service.
What are reclosers used for?
How do reclosers and Sectionalizers work?
After a preselected number of recloser openings, and while the recloser is open, the sectionalizer opens and isolates the faulty section of line. This permits the recloser to close and re-establish supplies to those areas free of faults. If the fault is temporary, the operating mechanism of the sectionalizer is reset.
