IEC60044-8 Electric Instrument Current Transformer for Switchgear
1 Product introduction:
The products accord with standard IEC60044-8, GB/T20840.8-2007, and can meet customer’ s other special requirements. The products use Rogowski winding to test current, mainly used in =s 20kV switchgear, match with electric instrument, digital measure and protective equipment, can at the same time realize multifunctions such as measure, control, protection and data transmission etc, secondary open circuit can not produce high voltage.
