The form of the secondary safety measure of typical case is divided into three partial contents,
Substation Design schema definition
The design of transformer station mainly considers the key element of following dimension：Voltage class, main wiring mode, relaying configuration,
Sampled form (electronic mutual inductor or routine transformer), whether using combining unit, whether use intelligent terminal.
Maintenance model is defined
Maintenance model will consider primary equipment power failure range, and (whole station has a power failure, voltage class has a power failure, interval has a power failure, do not stopped
Electricity), maintenance type (first inspection, routine test, defect elimination are upgraded).
Peace arranges objective for implementation and operation object to formalize
In operating standard, in the transformer station of every kind of design, each device type (busbar protective device, line
