Figure 3-22 Testing the measuring voltages in the measuring field — Example 2
If there is no transformer between the two measuring points – as shown in the above examples – address
6122 ANGLE ADJUSTM. must be set to 0°.
If the measurement is made across a transformer, this angle setting must correspond to the phase rotation
through which the vector group of the transformer (as seen from the feeder in the direction of the busbar)
rotates the voltage. There is an example in the setting notes of the synchronization function.
Checking with the Power Transformer
In the synchronization range, it is included a power transformer with tap changers is included as shown in
Figure 3-23. There are different methods to perform a test. The method without having the generator in oper-
ation is described. The generator circuit breaker including the isolator is continuously open and it is secured
against switching.
