1, the voltage measurement, provides a measure of the voltage meter circuit;
2, can provide power to operate and control;
3, each bus overvoltage protection device installed;
4, need protection, such as bus insulation, overvoltage, undervoltage, prepared from the cast condition, and so on.
(Power voltage switchgear screen top small bus voltage is provided by the PT cabinet, PT PT cabinet measuring both have metering PT (originally are required to measure PT and PT are separate measure, because specification metering transformer rank higher than the level of protection of transformers, but now there are no special requirements as there are not separate, shared), are on the top of the screen voltage small bus, providing measurement, measurement for the other qualifying high-voltage cabinet, power supply protection, etc.)
