The main purpose of line parameter testing is to obtain the measured parameters of the line. The measured parameters are different from theoretical parameters and have more practical significance in power flow calculation, power grid stability calculation, and protection setting
The substation equipment is more standardized and modular. Tests can be conducted before leaving the factory to calculate the actual parameter values. The circuit is assembled and synthesized in an outdoor environment (overhead or cable). Due to various influences such as wires, fittings, insulators, towers, etc., the actual parameters must be measured after the formation of the line
The external environment also has a certain impact on the testing of line parameters.
. When the humidity is high, the testing of circuit parameters will be greatly affected. The test values for circuit parameters will vary
Testing
Line parameter testing generally involves pressurizing either end of the two sections of the line and grounding the other end to form a closed-loop loop for measuring and calculating R and X parameters.
