6.6. Clean the Test Cell and Electrodes thoroughly and adjust the spacing of
the electrodes to conform to the proper IEC Specification. Be sure the
electrodes are securely tightened on the adjustment posts inside the oil
vessel. In order to adjust the distance between electrodes we will use the
gauge delivered with the equipment. The gauge must be placed between the
electrodes, and the distance between them will be corrected relaxing its
subjection by means of provided Allen spanner. Later it will be necessary to
tighten to maintain the required distance.
6.7. Locate sufficient insulating liquid for the testing to be performed.
6.8. Adjust the Voltimeter to zero if required.
6.9. Set the Rate of Rise to the appropriate rate for the test being performed.
The type of ramp we desire between the four possible ones, depending on the
standard we follow or depending on the indications of the oil manufacturer:
- 0.5kV/s, 2kV/s o 3kV/s.
2 kV/s is selected according to IEC-156 standard.
A note about the Oil Vessels made by Circutor.
All the oil vessels designed and made by Circutor Inc. have interchangeable posts and
electrodes. These oil vessels were designed to conform to the IEC-156 test
specifications requiring simple disassembly for cleaning. This design greatly reduces
the time and effort required keeping your oil vessels in top operating condition.
