IEC Three Phase Electromechanical Energy Meter with ABS , Bakelite , PC Terminal cover
IEC Three Phase Electromechanical Energy Meter Four wire
The DT86 three-phase fore-wire meter is designed to meet the latest IEC62053-21,IEC62052-11 standards for measuring active energy in three-phase four-wire alternating current power grids. Connection is direct or by instrument transformers.. It has an average service life(MTTF)of 20 years and maximum overload capacity of 600%Ib.
Terminal block
The terminal block is molded of heat-and flame-resistant Bakelite . It is fixed in the extended meter base. The voltage test link can be located inside or outside of the meter case.
Driving element
The driving element consists of a voltage element and a current element, both of which are fixed on the aluminum alloy frame. It has a load curve compensation device and inductive load adjustment mechanism.
Register Cyclometer single, unidirectional, Jumping
