Voltage input: The instrument transformer is rated
√
⁄
for the primary voltage and
√
⁄
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 primary current and
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 primary current and
for the secondary current. The secondary current is sensed with a current clamp with
voltage output and the transfer ratio .
