Pall Transformer Oil Purifiers

Pall HTP070 Transformer Oil Purifier

The Pall HTP070 transformer oil purifier permits treatment of the oil in a power transformer, while on-line and on-load. This method is called transformer oil purification.

The ‘PALL’ HTP070 oil purifier removes water, solid particles, air and other gases present in the dielectric fluids.
The operation of the HTP070 purifier is based on the principle of vacuum dehydration combined with fine filtration to remove particulate contamination.

The purifier is designed to treat power transformers while on load. It is an integrated unit consisting of a mobile purifier unit mounted on wheels, and incorporates an isolation system and has connection accessories.

In addition to on-load treatment of transformer oil purification, the purifier can be used for the treatment of bulk fluid.

Benefits of the Pall HTP070 Transformer Oil Purifier

  • High performance water, gas and particulate removal
  • Extension of fluid life
  • Minimised corrosion within systems
  • Reduced fluid disposal
  • Reduced operating costs
  • Increased equipment reliability
  • Simple automated operation

 

Typical specification for a new transformer

Water content at 20°C: < 10 ppm
Particle count according to ISO 4406: < 12/10
Particle count according to NAS 1638: < 4
Dielectric strength: > 75 kV

The above details show typical values for a new transformer. They must be adapted to suit the type of transformer, its age, and technology.

It is absolutely essential to keep the overall contamination level of the transformer oil in service at low levels to ensure the dielectric strength of the oil and to minimise the risk of transformer breakdown.

Note: For on-load treatment, the initial state of the oil and paper must allow normal and safe operation of the transformer. The PALL HTP070 purifier must not be used on fluids contaminated by toxic or volatile products, the vapours emitted being liable to present risks of explosion or otherwise endanger personnel. Strict compliance with the Safety Rules and with the Regulation in force at the point of use must be observed.
