KA outdoor rated substation class oil-filled current/voltage transformers are wound type single phase metering transformers intended for revenue metering. These current/voltage transformers are built-to-order to customer specifications. KA transformers can meet many revenue metering applications with up to four independent cores from 46 kV up to 245 kV. This combined housing is available with ANSI 70 gray porcelain insulator considered as the standard product, with silicone rubber (SIR) polymer as an option. Hermetic sealing of the design is accomplished using a fatigue resistant stainless steel bellows on the dome to prevent free-breathing outside moisture-ladened air.
The KA provides reliable performance in service due to the conservative insulation system used at the lower distribution voltages.
