摘要： PROBLEM TO BE SOLVED: To provide an electronic watt-hour meter for easily recognizing the degree of reverse current. SOLUTION: This electronic watt-hour meter has a reverse current level monitoring section 6 for monitoring the magnitude of the total-phase watt-hour and controlling the display state of a total-phase reverse current state display section 21a according to the magnitude of the total-phase watt-hour when the direction of the total-phase electric power is reverse direction. The reverse current level monitoring section 6 includes a reverse direction watt-hour counter section 6a for performing count up proportionally to the total-phase watt-hour. The fact that the total-phase electric power is in the reverse direction is displayed by coming of the total-phase reverse current state display section 21a into a lighting state. Whenever the reverse direction watt-hour counter section 6a counts it by a predetermined value, the total-phase reverse current state display section 21a is temporarily extinguished to come into a blinking state, and the degree of the reverse current is displayed with the blinking speed.

摘要： PROBLEM TO BE SOLVED: To solve a problem that the producing yield is lowered by fluctuation in cap width and an output is fluctuated when the cap width is narrow in a current transformer for alleviating magnetic saturation by providing a gap or a plurality of gaps to a part of magnetic path. SOLUTION: The magnetic core blocks, each of which is formed by laminating a plurality of magnetic thin plates, are abutted with each other via spacers and are then tightened with a tightening band from the external circumference. These magnetic core blocks are accommodated within a core case leaving a gap. A secondary winding is wound around the core case. These core cases and winding are then put into an armored case.
