Checking Sepam™ B80
Additional Voltage
Input Connections
Description
Conduct this check on Sepam™ B80 units with
additional phase voltage measurement. This does not
check the main voltage input connections.
The additional phase voltage the Sepam™ B80
measures is either phase-to-neutral voltage V’an or
phase-to-phase voltage V’ab. This is determined by
the VT connected and the Sepam™ parameter setting
mode.
Since the additional voltage measured is not related to
the currents measured by Sepam™ B80, it is not
necessary to inject current to check the Sepam™ B80
additional voltage input connection.
Procedure
Use the diagram below to perform the following steps
1 Connect the single-phase voltage generator to the corresponding test terminal
box, using the plugs provided, according to the diagram for the voltages
measured:
b block diagram 1: Sepam™ B80 measures the three main phase voltages
and an additional phase voltage
b block diagram 2: Sepam™ B80 measures two main phase voltages, the
main residual voltage and an additional phase voltage.
2 Turn the generator on.
3 Apply a voltage V
N set to the rated secondary voltage of the additional VT
(V’
Ln
s = V’
LL
s / 3).
4 Use the SFT2841 software to check that the measured voltage indicated V’an or
V’ab is approximately equal to the VT's rated primary phase-to-neutral voltage
(V’
Ln
p = V’
LL
p / 3).
5 Turn the generator off.
