New DC Immune Split-Core CT by Ball-effect Technology (KEPCO has replaced existing Smart Meter with all-in-one CT & PT Smart Meter)

October 9, 2013

A successful example is the case of Korean Electric Power Corporation (KEPCO). KEPCO chose the latest J&D model as a key component when installing solid state type electronic watt-hour meters. KEPCO has replaced existing meters with all-in-one CT meters to solve power theft and safety problems and the cost increase when connecting an outer mounted. CT and metering outfit of a 5A watt-hour meter. The new solid state watt-hour meter adopted J&D’s split-core CT which meets the standard of IEC62053-21 in open-type with DC Immune CT.
