product manual

JED(S)H series electronic voltage transformer is suitable for the neutral point solidly earthed AC power system, whose highest voltage for equipment is 66~500kV and rated frequency 50Hz/60Hz. It can be used for electrical measurement and relay protection, provide voltage signals for control devices. Electronic transformer is the trend of meter transformer development. Contrast to the conventional instrument transformer, electronic transformer insulation structure is easy, and with small volume, light weight, no iron and no ferro-resonance phenomenon etc. Anti-electromagnetism interference performance is good, dynamic range and frequency response is wide.
