Conventional split-core CTs with a magnetic core have limitations. They are vulnerable to external environmental factors that erode the core affecting electric parameters, which can result in overvoltage and surges. To avoid or lessen these problems, J&D has invented unique split-core outdoor CTs. Advantages over conventional split-core CTs: • added gasket to prevent core erosion […]
In generally, Outdoor Split-core CT which is being used for distribution transformer monitoring, is designed to fulfill IP67 standard. However, these current sensors are vulnerable to the external circumstances such as UV, rain, wind, vibration and lightning surge. Therefore, current sensors have to be covered with a protective housing when it is installed, to protect […]
Recently, sub-metering installation costs have been a hot topic because of the time involved installing CTs on a branch circuit. To mitigate this problem J&D has invented new solid core CTs, 1 and 3 phase and split-core CTs for branch circuit power meters. Our new J series with innovative design offers flexibility and safety. Advanced […]
iSAST OPEN CT Engineers of power and energy monitoring systems are concerned about choosing split-core current transformers (CTs) for high quality measurement without disconnection of the power line and problems pertaining to temperature change or vibration and installation safety. J&D’s split-core CTs are available as iSaST OPEN CTs with a magnetic core and iSaST OPEN […]
DC IMMUNE SPLIT-CORE CT BY HALL EFFECT TECHNOLOGY 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 […]
