I. Brief
1.1 Name and Model: 12kV pad mounted metering unit PMY6-12, combined transformer JLSZXW6-12
1.2 Description
This metering unit is for outdoor installation, in power distribution system upto 12kV(Um) for metering and measuring, with a factory-assembled three-phase combined transformer of CT, VT inside. Three-phase voltage transformers’ wiring method Y-Y star connection, and current transformer is optional, eg. two-phase CT, three-phase CT. Panel type is metal-clad, made from galvanized steel, stainless steel, or alloy aluminum. Enclosure surface is painted with color and protection layer for resistance to acid and alkali corrosion, and UV radiation. It is applied to connecting outdoor underground cable with utility company power system. The metering unit has two compartments, including a factory-assembled low voltage compartment for energy meter, and test terminal block of combined transformers. End customers can install a suitable energy meter in the compartment.

II. Application
Pad mounted primary metering unit can meet the latest standards nationally and globally. It is connected with power distribution net three-phase cable for power metering management and automation system, to get primary metering more accurately. Thus, utility company will account power loss more effectively and increase revenue.
III. Features
1. Metering unit consists of 4 compartments, including cable entry
compartment, cable outgoing compartment, MV combined transformer
compartment, and energy meter compartment. Adjustable feet
(supporting frame) structure enables this metering unit unaffected
by weather conditions, such as wind/flood/snow. Outdoor pad mounted
design is convenient and fast;
2. Metering unit has been factory-assembled as a complete unit,
door opening sensor for safety operation, lock sealable for
anti-theft electricity and unwanted open;
3. Enclosure made from stainless steel or equivalent material, such
as low carbon steel. Hermetically sealed design is waterproof.
Enclosure surface coating power is anti-corrosion layer, for
resistance to acid and alkali corrosion, and UV radiation;
4. Touch-proof type, medium voltage combined transformer is
encapsulated in casting epoxy resin with a metallic coating. No
need insulation between combined transformer and compartment. This
compact design vessel only needs 1/2 space compared with air
insulated metering unit. No oil and no need maintenance, safety
operation and environmentally friendly;
5. Primary side bushing connected through set of separable Tee
connector, which meets IEC 50810/IEC 50181 interface C, or A, B.
