Transformer Oil Filter Units Specialist in Australia :: Transformer Filtration Systems

Transformer Filtration Systems (TFS) offers a full range of new Vokes Streamline transformer oil filter units, spare parts and service throughout Australasia. We carry a large range of genuine Vokes spare parts including insulation oil filters, transformer oil filter units and Vokes streamline parts.

We offer existing clients  full technical advice to allow your equipment of any age to operate to original specifications.

TFS has been working in partnership with parent company SPX Vokes Streamline for over 15 years and is the exclusive Australasia agent for Vokes equipment and spare parts which also includes insulation oil filter & transformer oil filter unit range.

Insulation oil is vitally important for the safe and efficient operation of many types of electrical equipment. In addition to its insulating properties, the insulation oil is used as a coolant in transformers and as a means of arc suppression in circuit breakers. In each case the operation of the electrical equipment depends on the purity of the insulation oil, which in services can be contaminated by particles, water, gases and chemical products.

Should electrical equipment be continuously operated with contaminated insulation oil, it's efficiency will be impaired, resulting eventually in the risk of total failure. Typically transformer insulation oil is contaminated in the following ways:

• Particles including fibres, rust and colloidal carbon.
• Free and dissolved water.
• Gases produced by fluid ageing, equipment failure and arc suppression in switchgear
• Chemical products caused by oxidation, as well as cross contamination by other products.

Although individually each contaminant reduces the insulating characteristics of the fluid by around 20%, the combination of fibres from insulating material and water can reduce its performance by up to 90%.

Insulating fluid treatment maintains the integrity of the fluid and hence the efficient utilisation of the electrical equipment.
