This standard specifies the product classification, technical requirements, test methods, inspection rules, signs, instructions for use and packaging, transportation and storage of generator reverse power protection devices and reverse power relays. This standard applies to generator reverse power protection devices and reverse power relays. This type of product is used to protect the steam turbine-generator set. Due to reasons such as the closing of the main steam valve of the steam turbine, the generator can eliminate faults caused by reverse power operation and ensure the safe operation of the steam turbine-generator set. This standard only applies to new products.
