Common use of Autoreclosure and Manual Energization Clause in Contracts

Autoreclosure and Manual Energization. 1.5.1 The Generator shall provide suitable equipment to protect its plant and equipment for any conditions on the transmission system such as reclosing, faults, and voltage unbalance. 1.5.2 Following a protection operation on a transmission line, the transmission breakers, located mainly in network switching and/or transformation stations, shall autoreclose after a certain time delay. Where the Generator is directly connected to the transmission line, or for configurations where the Generator could be damaged by autoreclosure of the line, the Generator shall provide a reliable means of disconnecting its equipment before autoreclosure. The Generator is responsible for protecting its own equipment and the Transmitter is not liable for damage to the Generator=s equipment except as stipulated in section 15 of this Agreement. The Generator may request a means of supervising the transmission autoreclosure prior to the disconnection of its equipment e.g. changes in protection logic at one or both stations to reduce the risk of such events. The criteria governing the use of reclosures are set out in the Ontario Hydro APolicies, Principles & Guidelines@ document AC-3.4.1(R1), Automatic Reclosure and Manual Energization on Bulk System Electricity Circuits@, which was in effect as of April 1, 1999. 1.5.3 A Generator=s transmission system breaker shall not autoreclose without the Transmitter=s approval. 1.5.4 Manual energization of a Transmitter=s line by a Generator=s facilities is permitted only under the Transmitter=s direction.
