This standard specifies the system conditions, test requirements, test methods and test result processing for neutral point inter-frequency signal injection capacitor current testing. This standard is applicable to capacitance current measurement in 6kV ~ 35kV neutral point non-effectively grounded systems. The 66kV neutral point non-effectively grounded system can be implemented as a reference.
