Transformer oil filtration system - Trouble shooting and getting prepared for tomorrow while meeting today
In a result-oriented drive, Hering VPT focuses on purity and quality while generating oil filtration system, so that transformer operations are optimized. Such optimization, gives a winning edge to next gen transformers. Transformers are bound with responsibilities which demand effective power transmission and distribution network. Such demands, compel transformers to be checked regularly to ensure reliable service.
The current competition pushes our transformer oil filtration
systems to fulfill expectations to be a formidable coolant and effective
dielectric material. This in turn helps transformers to withstand stress
resulting from heavy loading and short circuit. Age might decay the oil, thanks
to oxidation and deposition of thermal by-products which results in
interruption and breakdown of the machines. Preventative maintenance thus
becomes inevitable. Parameters including electric, chemical and physical
features help Hering VPT deliver the right product.
The electric parameters include the BDV kit which is kept near the
transformer monitors the breakdown strength of voltage so that health of the
oil is constantly supervised. The resistance of the transformer oil, when
observed, protects the transformer in an overloaded condition, especially when
the temperature shoots up. The need for proper resistivity arrives at this
point.
The dielectric dissipation factor of the transformer oil is a
loss factor thanks to its insulating capacities. It is accepted as a tan delta
which increases with decrease in resistivity and vice versa. Separate tests for
resistivity and tan delta are not required as they are interdependent. Checking
the dielectric aspects through portable equipments of lab tests, mitigates
replacement expenses of the transformer. Coming to the chemical attributes,
moisture analysis of transformer oil is
vital, as it affects the dielectric properties.
Cellulose paper insulation absorbs moisture content and results in loss of
insulating property and hurts the lifespan of the instrument.
When the atmospheric oxygen reacts with transformer oil, it
encourages the acidic compounds leading to transformer failure. Eventually, the
insulating oil is dissolved by the acidic components and accelerates ageing. Coming
to the physical attributes, the interfacial stress which deals the existing
tension between the oil and water surface, flash point value of transformer oil where it
gives vapour and forms a mixture with air and thereby becomes inflammable in
nature, the pour point value and viscosity index of transformer oil are
understood while employing transformer oil Filtration system.
Transformer oil filtration systems differ
in purposes and a streamlined approach is what keeps Hering VPT, a
favourite of its customers. Client requirements vary inclusive of advanced
overhaul of transformer oil or
perhaps a comprehensive treatment of the transformer. The plant may be serving
purposes such as maintenance, first oil filling, oil filtration, oil degassing,
dehumidification, oil regeneration, transformer evacuation, hot oil spray
drying to name a few. Transformer capacity is terms of voltage, power rating
and oil content, also comes in the picture. The oil to be treated, be it transformer oil, new
oil, used oil or non mineral oil and their respective flow capacity are other
criteria. The professional in Hering VPT enjoys navigating into details while
providing the desired product. Such expertise powered by German Engineering is
obviously tagged as leading and benchmark brand.
By minimizing water content in the fluids, Hering EOK improves dielectric properties of the
transformer besides eliminating volatile acids. The increasing
voltages and the stress that such voltage is tagged with compels the user to
employ rich insulating fluid in initial impregnation and filling. Calculating
such demands, plants are categorised as EOK Basic, EOK Standard and EOK
Professional. Such a study is inevitable to remove sludge material and
contamination in transformer oil.
The components of Hering systems are carefully procured from German and
West European brand manufacturers so that longevity, efficacy and reliability
are reached.
Hering holds a rich legacy since 1909, which vouches for quality since
inception. While the initial product was a vapour-oil boiler which facilitated
internal and external oil treatment, the brand maintains lead in the industry till
date, thanks to the insatiable research which is never compromised.
