Question 1:

What is oil volume?

Question 2:

A mobile version of for permanent purification

Question 3:

Is a copy of a recent oilanalyse available?

PALL Industrial Hydraulics division, they are in Portsmouth, UK, and Port Washington (Long Island) USA. Look at the web site for more info.

Pall Corporation manufactures a series of purifiers. One particular model allows on-line, on-load oil purification....It is the HTP-070. Good luck.

The following are three manufacturers who supply good quality Transformer oil Filtration Units from India

Manufacturing and supplying at reasonable rates.

Be careful with this.

- May I ask if your plan is to work on the isolation oil on-line or off-line?

- Do you have a customer request or are you working on your own equipment?

There are several very important reasons, beside safety alone, for you (and anyone) to know about both the fluid and mechanical process changes when connecting a degasifying machine (below 1000 mbar) to a transformer.

INTERNORMEN

Fluid Purifier Systems IFPM / IFPS

INTERNORMEN fluid purifier systems are designed and built with quality components and craftsmanship to provide years of trouble-free service.

Systems for viscosity ranges from transformer oils to heavy gear lube oils (ISO 460), able to remove free, emulsified and dissolved water, free and dissolved gases and particulate contamination down to 1µm. Particle contamination is being removed in the fluid outlet filter. The fineness of the filter - ranging from very fine to coarse - is selected according to the kind of contamination.

Customers report clean fluids down to ISO 12/11/09. The product has demonstrated the ability to remove up to 546 litres of water from oil. Water removal has been demonstrated down to 8 ppm in transformer oils.

Fluid purifier systems are available in four different standard sizes from 20 to 100 l/min, mobile and stationary, and as explosion-proof as well.

The compact IFPM/IFPS systems have been constructed as fully automated, PLC controlled units applicable even in tight areas. The implemented on-line water monitoring sensor WSPS 03, in connection with the display unit WFD 01, allows a permanent monitoring of the water level in the purified fluid, and the electronic ∆p sensor VS1 provides the optimal use and maintenance scheduling of the included particle removal filter element.

Due to the reduction of fluid aging, the maintenance of lubricity and the decrease of the air- and water content, the equipment reliability of the whole system and the durability of the used fluids, are being significantly improved.

Dear machine manufacturers and sales people!

Before connecting all of your brilliant machines to a transformer in operation, I really miss the dialog around how to connect it, how to monitor the process and when to disconnect - and not to forget, how evaulate the machine performance and your "improvement" of the transformer condition?

Can anyone of you having replied to this forum thread give some input on;
- at what pressure level (mbar) is the best performance and for how long?
- is there a critical pressure level for the isolation oil stability, or how powerful is your machine?
- how many air bubbles do you allow in the pressure line to the transformer before it get's critical?
- how do you monitor your machine for air bubbles, such as a pressure vessel drain pump sealing leakage?
- what component in your machines have to be explosive proof protected?
- how "dry" oil and how high particle cleanliness can you produce in the aspects of electrostatic discharges and the total risk of causing an explosion?
- what is the best humidity level in the oil during winter season?
- what is the best humidity level in oil during summer season?
- at what oil humidity level do you get close to the collapse of the transformer insulation material (cellulose fibres)?
- how much of the explosive gas content can you remove from the oil without destroying the possibility to investigate a mechanical issue in the transformer?
- how often should you withdraw gas oil analysis per 24 hour, and do you have a qualified petroleum laboratory that can analyze the oil samples?

A transformer produces highly explosive gases, how much depends on the mechanical condition of the unit, and the gas content is used to track down the mechanical issues in the transformer. This is essential maintenance data that you take out when connecting your machines to a transformer and the data is used to find and change a failing component, before reaching a break down.

The humidity level in a transformer varies with season and also with the oil temperature, meaning daily, and the humidity balance betwen the surrounding athmospere - isolation oil - isolation material (cellulose fibres) is something one should know since taking out to much humidity from the oil will affect the humidity content from the isolation, which affects the isolation volume (strenght).

This is an "Engineering Forum" where we also should discuss the technical aspects of an issue - not only how to find the product and sell it. I have spent years of field testing vacuum units for conditioning of isolation oils to the major power companies and if you have no clue of what I am talking about - you should think this application through carefully an ddecide wether your company are qualified to connect a vacuum pressure vessel to a transformer in operation, or it could go very wrong.
