PVMC now has a piece of highly specialized equipment that prevents an outage nearly 100% of the time from its utility supply. This piece of equipment is known as an Automatic Throw-over Switch (ATO).
Utilizing the ATO, PVMC now receives electricity from two different sources from United Power. If one source of power is lost, the ATO automatically switches power to PVMC from the second source. The switch to an alternate power source occurs in a matter of seconds, causing only a slight a blink in power rather than an extended outage.
As part of its annual maintenance, on Thursday, May 12th at 10:30 a.m., United Power will interrupt the power supply from one source to verify the functionality of PVMC’s ATO.
“At this time we do not anticipate any issues with the maintenance tests, but there is a slight possibility that if it malfunctions an outage may occur,” explains United Power’s Manager of Operations Myke Weis. “If an outage does occur, PVMC’s back-up generation system will begin to provide adequate power supply until the primary power source is re-initiated.”
