11. Withstand voltage test
In the case of conducting withstand voltage test for CUS, please follow the instructions below.
• Make sure to apply the testing voltage to all three phases at a same time.
• Make sure to connect all three phases and N-phase of transformer secondary side to the earth.
• Make sure to connect the enclosure of CUS to the earth.
• Rated withstand voltage shall be 24/√3 kV for 10 minute (phase-earth).
• Make sure to wear the protection wearing when performing the test.
In the case of the CUS is equipped with RMU which has a plug in transformer [Type: GST20-B-Y-T],
the withstand voltage test above the rated voltage (24/√3 kV) is prohibited due to avoid the degradationof the plug in transformer.

12. After service
We recommend the periodical inspection of RMU and transformer every year.
If abnormal deposition or adhesion of dust is found, please contact the manufacturer.
For technical inquiries, please contact us at the followings:
