ENERGY THAT CHANGES THE WORLD
An effective maintenance plan requires of:
VISUAL PERIODIC INSPECTION
You need to register: The values of current, load voltages,temperature of dielectric oil and windings, nitrogen pressure, oil level. Transformer general inspection and unusual sounds.
ELECTRICAL TESTS ON THE UNIT
A several electrical tests are performed on the transformer, unit and transformation chamber cleaning is necessary every 2 or 3 years depending on the loadability of the equipment.
PERIODICAL PHYSICO-CHEMICAL STUDY OF THE OIL
The oil sample is taken in a suitable container used for this purpose. It is used to determine the quality of the oil and to diagnose the condition of the paper – oil insulation system to perform an adequate maintenance to the transformer.
CHROMATOGRAPHIC STUDY OF GASES TO DETERMINE INCIPIENT FAULTS IN THE TRANSFORMER
It allows to detect the concentration of combustible gases and their composition ratio to incipient or advanced failure of internal discharges, crown effects and cellulose or oil overheating, allowing us to program an internal inspection of the unit and avoid important faults in the transformer.
