摘要： PROBLEM TO BE SOLVED: To provide a capacitor-type instrument which can prevent a voltage vibration produced at the time of restoration after secondary short circuiting during test of resonance with iron. SOLUTION: An inhibitor 7 of resonance with iron comprising of a series circuit of a saturatable reactor 8 and a resistor 9 is parallelly connected to the secondary side of a transformer 4. A series circuit of a filter capacitor 21 and an adjustment reactor 22 is serially connected to the saturatable reactor 8. The saturatable reactor 8 is not saturated for a voltage of 1.2 times or less the rated voltage. The capacitance of a filter capacitor 21, the inductance of the adjustment reactor 22 and the inductance of the saturatable reactor 8 in non saturated state are set so that a parallel circuit of a series circuit of the filter capacitor 21 and the adjustment reactor 22 and a saturatable reactor 8 in non saturated state may satisfy the resonance condition at a rated frequency.

摘要： PROBLEM TO BE SOLVED: To provide the primary winding of a transformer for a meter, which can prevent voltage between layers from becoming high and interlayer insulating layer from becoming thick on the inner side part of a winding. SOLUTION: Groups W1 to Wn of winding layers are wound on the outer periphery of a spool B in a state that insulating layers L1 to Ln-1 are made to interpose between the winding layers, and the sectional form of the half of the whole winding is formed into a trapezoid shape. The groups of the winding layers are divided into the first groups W1 to Wm of the winding layers, which are positioned on the side close to the spool, and the second groups Wm+1 to Wn of the winding layers, which are positioned on the outsides of the first groups of the winding layers. The first groups W1 to Wm of the winding layers are formed by winding two parallel conductors C1 and C2 and the second groups Wm+1 to Wn of the winding layers are formed by winding one conductor C.
