Standard outfit: :
1 coil with approx. cylindrical outside and inside surface, ironless, free of distortion, power factor cos without combination with effective resistors approx. 0,1, permitted voltage in continuous operation: 275 V,
20 tappings, or more if necessary, steps for inductance less than 1% of maximum inductance, connection with threaded bolts of brass, inductances and amperages of the steps at prescribed relative operation time in accordance to the requirement to the entire set-up or by agreement,
1 resistance set, shunted, for approx. 1% of the inductor amperage,
Design: Enamelled or covered copper wires, selfsupporting, glued by synthetic castresin, on base plate or on base frame.
Special outfit:
Toggle switches
to switch over the inductance
