In order to measure the iron loss of the silicon steel plates, we produced a vectormeter using a thyristor and a gate turn off thyristor by way of experiment. This equipment is very useful, because the frequency range is
improved very much in comparison with the vectormeter which is composed of the mechanical rectifying system using a synchronous motor, namely, is enlarged from 60Hz to 1kHz,
