METERING
Equations to be applied for powers in a wye connection are as follows:
Apply the following current and voltage values:
With the indicated voltage and current values, verify that the power measure corresponds to expected values indicated in
the following table:
Maximum admissible error is ± 1% of the test value for P and Q, and 0.02 for cos
ϕ
.
6.7.4 FREQUENCY
Frequency measure on channel VII (terminals A7-A8):
Apply 50 Vac at 50 Hz on channel VII. Maximum admissible error:± 10 mHz.
Apply 50 Vac at 60 Hz on channel VII. Maximum admissible error: ± 12 mHz.
Frequency measure on channel Vx (terminals A11-A12):
Apply 50 Vac at 50 Hz on channel Vx. Maximum admissible error:± 10 mHz.
Apply 50 Vac at 60 Hz on channel Vx. Maximum admissible error: ± 12 mHz.
