<p>PURPOSE:To reduce magnetic flux infiltrated into a current transformer, by arranging branch bus lines in the direction orthogonal to a plane with arranged main bus lines. CONSTITUTION:Current flowing to respective branch bus lines 12-14 is half the current flowing to main bus lines 1-3 in a flow rate, and current flowing to the other end section flows in the direction opposite to current flowing to the one side end section of the respective branch bus lines 12-14. Accordingly, to current transformers 9-11, many magnetic fields generated by current flowing to the branch bus lines 12-14 are cancelled. Besides, half current flows to branch bus lines 15, 16, and is separated from the current transformers, and so magnetic fields infiltrated into the current transformers 9-11 are reduced.</p> |
