Apply the three-phase balance current at 10% of the rated current and interrupt a phase
current.
Then, check the BCD element operates.

Operating value test of OVS1, OVS2, OVG1, OVG2
•
Apply a rated voltage as shown in Figure 6.5.1.6.
•
Increase the voltage and measure the value at which the element operates. Check that the
measured value is within
±
5% of the setting.
Operating value test of UVS1, UVS2, UVG1, UVG2
•
Apply a rated voltage and frequency as shown Figure 6.5.1.6.
•
Decrease the voltage and measure the value at which the element operates. Check that the
measured value is within
±
5% of the setting.
