Testing the synchronizing function

M2377-21 v8

The voltage inputs used are:

UP3LN1

UL1, UL2 or UL3 line 1 voltage inputs on the IED

UP3BB1

Bus1 voltage input on the IED

Testing the frequency difference

M2377-116 v11

The frequency difference test should verify that operation is achieved when the frequency

difference between bus and line is less than set value of

FreqDiffMax and above set value of

FreqDiffMin. The test procedure below will depend on the settings used. Input STARTSYN

must be activated during the test.

FreqDiffMax = 50.2 Hz

FreqDiffMin = 50.01 Hz

tBreaker = 0.080 s

Apply voltages
1.1. U-Line = 100%

UBaseLine and f-Line = 50.0 Hz

1.2. U-Bus = 100%

UBaseBus and f-Bus = 50.15Hz

Check that a closing pulse is submitted at a closing angle equal to calculated phase angle

value from the formula below. Modern test sets will evaluate this automatically.

Closing Angle = |( (f

Bus

– f

Line

) * tBreaker * 360 degrees) |

Bus

= Bus frequency

Line

= Line frequency

tBreaker = Set closing time of the breaker
