JLSJWS Series Oil-immersed High Voltage Metering Box
1. General
AC immersed outdoor type high-voltage power metering box (called combined transformers without metering) is use to measurement the power consumed in high-voltage electrical network. It suitable for 50Hz and 60Hz three phase AC 35kv, 10kv, 6kv, 3kv power system. High accuracy, light weight, easy to install and anti-tamper, welcomedy the majority of the electricity sector, enhance supply management.
Three-phase four-wire three 3 components high voltage metering box (combined transformer) make from 3 potential transformers (PT) and 3 current transformers (CT). PT and CT are the electromagnetic, three PT winding are connect as Y/Y shape, the primary winding of 3 CT are connect to phase A, B, C separately.
