Installation Manual for 35kV Poured High Voltage Metering Box

Xi'an Pinggao has a stock JLSZV-35 dry-type power metering box, which is composed of two single-phase fully insulated voltage transformers with a three-phase "V" connection. The A and C phases are connected in series with two current transformers respectively. It is used for active and reactive energy measurement in outdoor power systems with a rated voltage of 10KV. The current transformers can be made into high-precision and variable ratio structures, which brings convenience to future system capacity expansion.
