*Accuracy specifications are valid, only if:
• Parameter estimation is enabled in two ended (that is,
EnParamCorr= ESTM)
• Remote data is synchronized upto < 10 uS
• Sinusoidal input
• Voltage range: (0.1-1.1) x U
• Current range: (0.5-30) x I
• The accuracy of fault locator depends on the accuracy of
line parameters in case of EnParamCor = SET mode.
