| Marathon Substation
Marathon Substation is
now in service and operating to serve the Kenai area. The new Substation utilizes
state-of-the-art microprocessor based control, relay protection and metering devices. The
metering devices give the system operator accurate, real time load information on the 4
circuits that leave the Substation to serve the Kenai area customers. The Substation relay
protection devices provide fast and accurate tripping of the breakers at the Substation to
protect the equipment at the sub and the circuits that exit into the Kenai area. In
addition to providing high quality protection, the relays offer detailed fault information
that is essential in investigating disturbances. They offer this information in 1/4 cycle
increments, (there are 60 cycles in 1 second). HEA is proud of this accomplishment and
that Marathon will be serving customers well into the future. |
