1.0.1 This code specifies the fundamentals, contents and requirements of electrical measurement and energy metering device design in power plants and transformer substations, excluding the test instrument design in the electric laboratories.
1.0.2 This code is applicable to those steam-turbine/gas-turbine thermal power plants whose unit capacity is equal to or larger than 50MW, those hydropower plants whose unit capacity is equal to or larger than 10MW, those pumped-storage power plants whose unit capacity is equal to or larger than 10MW, those transformer substations whose rated AC voltage ranges from 35KV to 500KV, and those DC converter stations whose rated DC voltage ranges from 100KV to 500KV, either newly-built or extended.
The newly-built and extended power plants, transformer substations and DC converter stations that disaccord with the aforesaid provisions may take this code as reference.
1.0.3 This code just specifies the collection scope for the electrical measurement and energy metering data of computer monitor (control) system, as well as the configuration of general measuring meters. The setting and functions of the computer monitor (control) system, remote measurement and metering system in the power plants and substations shall be compliant with the relevant requirements and codes.
