Introduction was made to the structure, principle, main technical parameters and engineering application about the first domestic set of 500 kV DC electronic current transformers. This product made the shunt sense DC currents, the Rogowski coil sense harmonic currents, the remote module sample the output signals of the shunt and Rogowski coil based on laser energisation and the optical fiber transmit the measured signals, to realize measuring DC currents and harmonic currents at the same time. This product has the characteristics of simple insulation structure, small volume, light weight, good linearity, high accuracy, and quick step re-sponse. Practical engineering application shows that the product is stable and reliable in operation with broad application prospect.
