• Besides unbalanced neutral current which is calculated by the three-phase root mean square (RMS) currents, there is still more neutral current that is zero sequence harmonic current. Non-Linear Loads like SMPS, OA equipment, LED, etc., introduce third order harmonics. Third harmonic currents are in-phase on each of the supply phases and therefore will add into the neutral which can cause the neutral current in a wye system to exceed the phase currents. A PQ Terminal dramatically eliminates the zero sequence harmonic current by removing about 95% of neutral current in a distribution board.
  • Multi Green Energy (Multi-GEM) offers reliable and accurate energy monitoring & management in real-time at electric multiple feeding points. The Multi-GEM 18 automatically provides metering, demand, energy readings and loggings over multi feeding points with Multi-GEM 18 channels monitoring from the 18 feeders for 1P2W, 8 feeders for 3P3W, 6 feeders for 3P4W or any combination of single and three phase circuits. This useful flexibility makes Multi-GEM18 to be effective at IDC (Internet Data Center), office buildings, and shopping mall and the other industries that require multi metering.
  • The JS24S-5A series of precision, split-core current transformer by J&D offers a 5Amp output signal based on the model and ratio to the source current. The JS24S-5A series is designed to be directly connected to a meter to eliminate the need for internal CTs yet provide accurate readings. The JS24S-5A includes an over-voltage protection circuit which provides an added level of safety to the unit.
  • The JRFS Series of Clamp-on Flexible Rogowski coil current transformer by J&D is designed for accurate measurement of AC current with a safe output voltage RMS. The JRFS-075 series is the precision current probe for Revenue-Grade Distribution transformer monitoring. With voltage integrator configuration, it can replace existing CT directly.
  • eSmart metering uses a clamp-on current sensor that measures the magnitude of the current flowing in the AC power supply of any electric operated equipment. The compact design and quick installation method provide an easy and economical solution for your metering demand. eSmart metering can apply on any Single phase 230/240Volt and 3phase 400/415Volt systems. The data from the energy meter that is connected to the current sensor can be transmitted over a public or private network. The energy data can be uploaded every minute or at regular intervals. The meter provides energy profiles real time and the energy trending can be viewed from a mobile application platform. The meter can be integrated to any energy management platform via a gateway router, 3G/4G or any wireless communication.
