I am working in Japan electrical safety & environment technology laboratory, which is called JET for short. In JET, we are carrying out the safety test of electrical equipment according to Japanese domestic standards or IEC standards. And in my section, our stuff is drafting some national safety standards harmonized with IEC in cooperation with the government. The standards are applied for the mandatory regulation and other schemes.……展开更多

By leading false foot wires and taking advantageof the transmitting frequency band of Mo-Zn ferrite, detonators in this new system can completely impede the direct induction of outsidecrosstalk that may cause casual firing in the ordinary as well as eleclromagnetic ones. Possible causality by lightning was discussed. Results are presented, of its safety tests on resistance to direct and alternating current, electrostatic, and crosstalk induced by damp leakagein saturated salty water.展开更多
