Outline JP & JN series The JP & JN Series are high precision CT complied with Electronic Watt-Hour Meter (0.1 / 0.2 / 0.5 class) these are designed for power plant, distribution and industrial instruments. These have excellent properties of phase angle error and linearity error in the low current. The JP & JN Series are closer to zero on the temperature dependence. The JP & JN series for Electronic Watt-Hour Meter are complied with IEC 62053-22, ANSI C12.xx and EN 50470-3. We also design indirect connected CT (industrial meter) and direct connected CT to the main(residential meter). JDTN series...
