2.1 The product, a combined apparatus consisting of a voltage transformer and a current transformer, is suitable for outdoor. It is of small volume and good performance. There are multi-taps at the secondary windings, which make different current transformation ratio for the current exchange of customers while power consumption increasing.
2.2 The product is especially suitable for HV metering, to do so, two JJLDHW-10(X) voltage transformers shall be conneted in V type, while two current transformers connect seriesly to phase A and C. The instrument transformer can be fixed on the post of transmitting line. The secondary output connects directly to an independent HV metering box. Users can choose certain connection in accordance with different conditions.
2.3 Detailed technical data and outline drawing shall be provided under request.
