SUBSTATION SAFETY TRAINING
A Substation Training Meeting was held at the Davis Substation in Southern Iowa EC territory to review safe working practices in substations.
KIRKSVILLE CAPACITOR BANK SPLIT
Northeast Power has several capacitor banks scattered throughout the system. The purpose of the capacitor banks is to help boost the voltage in the event a line outage causes a voltage drop. Closing in a capacitor bank can help raise the system voltage. Over time, the size of the capacitor banks has been increased to the point that closing in the banks can create a very large but very brief voltage surge. This surge can be disruptive to some electronic equipment in manufacturing facilities. As a result, Northeast Power has elected to split some of the larger capacitor banks into two smaller banks to reduce the effects of the voltage surge and to provide flexibility when using the banks.
Northeast Power has evaluated the growth on the sides of the rights-of-way and found it is time to trim once again. In 2021, we contracted the trimming of 218-miles of transmission right-of-way utilizing a single contractor and ground-based equipment. A plan is being developed for trimming in 2022 and moving forward, lines will be scheduled for trimming as needed.
HART CIRCUIT BREAKER AND RELAY UPGRADE
Northeast Power is replacing older, high-maintenance circuit breakers with newer breakers at several of our older facilities. Currently, circuit breakers were updated at the Hart Switch Station in Macon Electric Cooperative service territory. Along with the circuit breaker upgrade, relays were also upgraded to the latest microprocessor technology.
LAPLATA TAP MOTOR-OPERATED SWITCHES
Northeast Power is replacing older, manually-operated 69 kV line switches with newer, remote-controlled switches that come equipped with load-break devices. The most recent location for a switch upgrade was on the Laplata Tap. These motor-operated switches will help sectionalize a 69 kV line between Macon Electric Cooperative, Tri-County Electric Cooperative, and the City of Laplata.
