10kV High-Voltage Metering Boxes · Outdoor installation
Outdoor combined metering unit built from two parts: a five-column combined transformer and a separate meter box. Two current transformers and two single-phase voltage transformers in V/V connection form a three-phase measuring device inside a stainless-steel enclosure; the armoured secondary cable and separated meter box give strong anti-tamper protection, and the three-phase active and reactive meters are read through an observation window.
The JLSZY-10 is a 10 kV outdoor high-voltage metering box combining current and voltage transformers with a separate metering compartment in a stainless-steel, tamper-resistant enclosure.
Two CTs and two VTs in V/V connection form a complete three-phase measuring unit for utility revenue metering, with accuracy combinations such as 0.2S/10P10, armoured secondary cabling and an observation window for active and reactive energy meters.
