Abstract
In order to provide positive control at all times on a 345-kV underground cable interface designed to transfer up to 1000-MW a Programmable Controller (PC) has been installed at PSE&G´s Waldwick Switching Station. This PC will independently take corrective action by moving phase angle regulator transformer (PAR) load tap changers (LTC) upon recognition of local flows exceeding emergency ratings after a time delay of five minutes. The PC has undergone extensive testing to prove the correctness of its logic and has been in service for more than one year.
