3 Terms and Definitions
The following terms and definitions specified in GB/T 2900.50 are applicable to this
document.
3.1 High voltage, HV
The voltage level exceeding 1kV.
NOTE. In specific condition, it indicates the transmission voltage level in the power system.
3.2 Electric power utilization
The behavior of using electricity for a intended purpose.
3.3 [Power] consumer
The party receiving the power supply from the grid and power plant.
3.4 Important power consumer
The electric power utilizing organizations or electric power utilizing sites having specific
reliability requirements for the power supply, which take a crucial position in the social,
political, economic life of certain region (city) or country; the power-off of which may
lead to personal injury and death, greater environmental pollution, greater political
impact, greater economic losses, and serious confusion of social and public order.
3.5 Double power supply
Two buses from two different substations, respectively, or two buses in the same
substation with different power incoming lines; two power supplies generating load
electricity to the same consumer.
3.6 Double circuit
Two power supply lines generating load electricity to the same consumer.
3.7 [Electrical equipment] defect
the upper and lower levels of cooperation, 110kV and below device is suitable for
adopting the integrated digital protection device with the protection, control,
measurement, acquisition and communication functions. The relay protection device
with voltage level 220kV and above shall be configured by the duality principle.
6.3.4 The low-voltage configured electronic release shall combine the load
characteristics to have the delay or instantaneous protection function.
