Accuracy
All instrumentation data accuracy is defined within the voltage range 20 % of the
stated nominal voltage and within the current range 5 % of the base current to the
maximum current.
The accuracy of all instrumentation data except the frequency and voltage and
current phase-angles is the same as the stated energy metering accuracy. The ac-
curacy for the voltage and current phase-angles is 2 degrees and 0.5 % for the
frequency.
