Switchgear Line vs Bus PT''s
When considering Double-ended MV M-T-M switchgear is it standard practice to have PT''s located on line side of main breaker, load side of main breaker (bus PT''s), or both? I guess
Using Potential Transformers
Therefore, we recommend using phase B as the reference and tying it to ground and neutral. This will result in zero readings for phase B from the meter. Note,
Using Potential Transformers
If your PT has a different secondary voltage, you will need to make sure the WattNode meter''s voltage rating matches the secondary voltage. The following
