Abstract

PURPOSE:To enable performance of a stable test with inexpensive equipment by fitting a box for connecting a testing bushing higher in position than a conservator and by applying pressure on to the surface of oil in the conservator. CONSTITUTION:The box 9 for connecting the testing bushing and the oil-air bushing 10 for testing are provided just above a tank 7. An airing piping 11 is fitted to the conservator 5 and air or gas is sent in through the piping to apply pressure on to the surface 5A of oil in the conservator, whereby the pressure in the part 9A of the box 9 higher in position than the surface 5A of oil in the conservator is made higher than atmospheric pressure.
