√
for the secondary voltage.
The primary quantity is the primary voltage:
The secondary voltage is measured with DANEO 400:
At nominal primary voltage we get:
Current input: The instrument transformer is rated
for the secondary current. The secondary circuit is terminated by a shunt with the value
.
The primary quantity is the primary current:
The voltage across the shunt is measured with DANEO 400:
At nominal primary current we get:
Current input: The instrument transformer is rated
for the secondary current. The secondary current is sensed with a current clamp with
voltage output and the transfer ratio
