OIL SAMPLING

Transformer oil test can be classified as

follows:

The full test done on transformers

include kV tests, moisture tests,

DGA tests as well as the testing of

acidity levels within the oil.

The normal tests done on

transformers include only kV

tests, moisture tests as well as the

testing of the acidity levels within

the oil.

PCB exact count (ppm).

Furanics test.

Tan Delta and interfacial tension

as well as others.

Contact our companies' sales

representative for more information on

the types of tests that can be

performed.

WHICH SERVICE DO YOU REQUIRE ?

TRANSFORMER SERVICES

We specialize in the installation and

commissioning of transformers up to

315 MVA but also provide the following

service:

Repairs on transformers such as

Oil leaks, tap changers, bushings

etc.

Rewind of transformers.

Testing of transformers (Full

commissioning tests can also be

done, if requested).

Cleaning of transformers

Spray painting of transformers

Purification of transformer oil ( we

attend to the purification of the

oil, either off-line or on-line)

Onsite regeneration of

transformer oil

Supply and delivery of mini-subs.

We also buy and sells

transformers.

PURIFICATION OF TRANSFORMER

INSULATING OILS

The following specifications describes

the plants used by PNC Oil CC for the

filtration of transformer insulating oil.

The purifiers are designed for filtration

of transformer oil in workshops, storage

tanks, drums or directly in transformers.

Purification of oil in transformers can be

carried out off-load or on-load

depending on customers' preference.

​Water Removal:

Water is removed by heating the oil

passing it through coalesces inside a

vacuum chamber. During this process

water and oil are separated and clean

dry insulating oil are returned to the

transformer.

​Gas Removal:

During the vacuum stage of the process

all dissolved gasses are removed from

the oil, leaving it clean, dry and gas free.

Oxygen, as an accelerator of oxidation,

is also removed.

Particulate Matter Removal:

98% of all particles over .5 micrometre is

removed.

Dielectric Strength:

Improvement in dielectric strength, up

to 70 kV, with new oil.
