The combined transformer (another name is metering tank) is one kind of outdoor power measuring instrument , which is composed of two sets single-phase wholly insulated voltage transformers, forming three-phase V/V wiring, and two current transformers are separately series connected to A and C phase.
The JLS-6, 10, metering tank is one upgraded product based on old product of same kind, just adding moisture-proof device onto oil tank's cover, which could effectively prevent external humidity from entering into oil, so as to prolong service life of product, while, compared with old product, its advantage contains larger capacity, smaller volume and weight, simplifying installing.
This product is applied to certain outdoor circuit of AC50-60Hz, rated volt being 35kV or lower, to be used for metering of current, voltage and electric energy etc. this product is suitable for rural outdoor transformer substation, miniature transformer station and substation of industrial enterprise etc. Adding active and reactive energy meter onto combined transformer is named as high volt power metering tank.
