Metering Current Transformer Wiring Diagram. 120240v single phase 3 wire under 60kw form 2s bridge. I always try my best to make simple and understandable diagram.
Current transformer wiring diagram a ct under test is assumed to have correct polarity if instantaneous current direction for primary. Meter panel fuse not required for an overhead supply. Btm 60kw no ess this diagram is representative of a standard design.
I can also do it without connection with one anther but the main reason behind this is that in real life we do our wiring like above diagram in our main power panel boards.
Interval metering energy values are recorded for a specific time period on a continual basis. Typically 1minute 5 minute 15 minute or 1 hour intervals. Install the ct to the primary connection on most cts this means passing the primary conductor through the aperture in the ct. This is a safety precaution to protect against static voltages or insulation failure.
