In case of using a large-sized crane near a high power medium wave transmitting station, high-frequency voltages and currents are induced by electromagnetic induction, which can be dangerous to workers. We have developed a equipment for reducing electromagnetic induction at the hook of a crane. Use of a ferrite toroidal core has attenuated the high-frequency energy to human bodies by making use of thermal losses of the core and high impedace part coupled with a parallel resonance clrciut.
