Values to be set for a voltage transformer:
• Rated voltage of voltage input (same as the secondary rated voltage of the
primary voltage transformer connected to the voltage input, 100 V, 110 V, 115 V,
120 V).
• Rated voltage of primary voltage transformer (0.100...440.000 kV)
• Amplitude correction factor of the primary voltage transformer voltage at rated
voltage (0.9000...1.1000).
• Correction parameter for the primary transformer phase displacement error at
rated voltage (-2.00°... 2.00°).
Values to be set for a current sensor (Rogowski coil):
• Secondary rated voltage of the current sensor used at the preset primary rated
current (100...300 mV)
• Primary rated current of the current sensor used (1...6000 A)
• Amplitude correction factor of the current sensor used at rated current
(0.9000...1.1000).
• Correction parameter for the phase displacement error of the current sensor
4
(-1.0000°...1.0000°) .
Values to be set for a voltage divider:
• Division ratio of the voltage divider primary and secondary voltage (1...20000)
• Rated value of primary phase-to-phase voltage (0.100...440.000 kV)
• Amplitude correction factor of the voltage divider (0.9000...1.1000).
• Correction parameter for the phase displacement error of the voltage divider
4
(-1.0000°...1.0000°) .
Values to be set for general measurement:
• Amplitude correction factor of general measurement
(-10000.00000...10000.00000).
• Correction parameter for the offset correction of general measurement
(-10000.00000...10000.00000).
1. For Release 1.0, the voltage range is 0...150 kV. For Release 1.5 and Release 2.0, the
range is 0...300 kV.
2. Prior to Release 2.5, the voltage range is 0...300 mV.
3. Prior to Release 2.5, the current range is 0...6000 A.
4. Only included in the feeder terminal revisions of Release 2.0 or later, refer to Section
"Revision identification" on page 105. Note that this parameter can only be set via
the HMI or the Relay Setting Tool.
5. Prior to Release 2.5, the division ratio is 0...20000.
6. Only included in the feeder terminal revisions of Release 2.0 or later.
