Transformers
AM Transformer Services
Oil in the transformers needs to be routinely sampled, the results of these samples will indicate the status and health of the transformer.
This serves to confirm that AM TRANSFORMER SERVICES, works with the highest integrity, therefore in our services we undertake to do your oil sampling and send them to Oilwatch to be analysed. This is a registered laboratory and is ISO 9001, ISO 14001 and 17025 registered company.
On receipt of the reports, AM TRANSFORMER SERVICES will send you the accredited report, with a quotation should any further work to be done.
AM TRANSFORMER SERVICES employees highly qualified transformer services staff with over 25 years of experience in this field. AM TRANSFORMER SERVICES will send a fully qualified team to do any work on your premises which includes:
TRANSFORMER MAINTENANCE | OIL SAMPLING AND ANALYSIS | OIL PURIFICATION | SWITCHGEAR MAINTENANCE | ELECTRICAL SCANNING | HV VAULT FINDING
Optimising Transformer Function Requirements!
The quality of insulating oil is vital to the functioning and early fault detection of power transformers in order to optimize equipment life.
Oil in service will need to be routinely sampled. The results of these analysis will indicate the status and health of the transformer.
It is vital that all decision’s regarding insulation oil are based on the prescribe analysis, following a correctly taken sample.
A significant method of testing the condition is by taking them to be analyzed by an accredited laboratory.
The following should be carried out :
- GAS
- Moisture content (ppm)
- Dielectric strength (Kv)
- Acidity (mgKOH/g)
This process entails the usage of a mobile filtration plant in order to remove moisture and fibers only.
This process is recommended to be used when the oil will remain in the transformer.
By separating and quantifying the gases found dissolved in the oil the specialist can identify the presence of an incipient fault. (early warning)
Is the measure of the oil`s ability to withstand electrical stress without failure.
Water accelerates the deterioration of both the insulating oil and the insulating material.
An increase in the acidity is an indication of the rate of deterioration of the oil with “SLUDGE” as the inevitable by-product.
Is a banned substance.
The term PCB is a generic name for a group of fire resistant dielectric fluids and synthetic insulating liquids.
Polychlorinated Biphenyls , also known as PCB`s , are a group of synthetic chemicals that are similar in structure with different degrees of chlorination.
PCB`s were banned due to their toxicity and persistence in the environment.
PCB`s were used in a wide range of industrial activities as a heat exchanger Fluid.
PCB`s causes environmental problems because they do not breakdown and can spread through the water , soil and air.
PCB`s have been shown to cause a variety of adverse health effects and are associated with acne like skin conditions in adults.
