Abb has combined current and voltage transformers that are used to transform high currents or voltages to values that can be unified or measured safely with low internal losses. Juk oil-insulated current/voltage transformers is the combined instrument transformers that consists of a current and voltage module enclosed in a common aluminum, hermetic casing filled with transformer oil. The various parts of juk are as follows:
1 bottom tank with voltage transformer
2 porcelain or composite insulator
3 head with current transformer
4 shielded expansion bellows
