Oil Sampling Kit for hermetically sealed transformer

This kit can be used for oil sampling from hermetic transformers and electrical equipment.
The hydraulic couplings provided with this kit are also suitable for sampling of oil or free-gases from Buchholz relay.

When not energized, sealed electrical equipment may be at negative pressure. For this reason, taking-out oil samples for diagnostic purpose is a critical operation, which may result in damaging the transformer sealing and air introduction.
This sampling kit allows:

  • hydraulic connection to the bottom valve and to the DGPT2 or similar protection devices
  • suction of air from the sampling hoses, before opening the sampling valve
  • suction of the oil, under negative pressure (vacuum)
  • suction of oil samples from drums or tanks
  • suction of air from the top of the equipment, if needed.
