IS-12463/1988 Specification for inhibited mineral insulating oils. In the case of poor washing, there are enough salts and soap in the oil which can leave unacceptable quantities of ash when the oil is burned. GENERAL TRANSFORMER SPECIFICATION. off-specification used oil (does not meet the requirements). If you disable this cookie, we will not be able to save your preferences. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Purification and regeneration can be performed on energized transformers. This system can remove water and solid particles from the oil. <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>>
This is not the main parameter, but provides some information on the actual quality of the oil. endobj
Castrol Insulating Oil is a pure mineral hydrocarbon oil, specially refined and blended from selected crudes. Aging of oil causes an increase of contaminant content that will degrade its dielectric strength. Protects the Paper from chemical attack 4. ⢠Types of taps. Technical Specification for 33/11kV Power Transformers ( APDRP Scheme ) ... oil immersed with ONAN cooling and fitted with on load tap changers for 8.00 MVA Transformer only. The properties of the transformer oil define its area of application. It is an uninhibited transformer oil, optimised for high performance to meet the stringent requirements of the IEC 60296:2003 specification. It applies to oil delivered to the agreed point and time of delivery, intended for use in transformers, switchgear and similar electrical equipment in which oil is required as an insulant and for heat transfer. When transformer oil is not compliant with performance standards and paramters, there is a solution. Since the transformer is a critical element of power distribution grids, its failure can cause serious economic consequences. When hot, it is less, when the oil is cold, it is more. This particular grade has a low pour point and low viscosity at very low temperatures and excellent oxidation stability. Physico-chemical properties Volume Weight. Test Properties Test Method Specification; 1: Appearance: Properties and specifications of transformer oil are as follows: Color. APPLICABLE STANDARDS IEC 60076-1. The latter two are unacceptable since this chemical element can intensify corrosion and increase resistance of contacts in transformer switches. Portable Transformer Oil Purifier/Degasifier (E865C) Transformer Oils manufactured by Panama Petrochem Ltd are from selected, severely Hydrotreated Naphthemc & Isodewaxed / Hydrocracked Paraffinic Oils and Naphthenic Oils that are free from polar compounds, having high oxidation stability and ageing properties. Our company designs Mobile Type Transformer Oil Filtration Plant that are utilized for dehydration, filtration and degassing of insulating oil. Inhibited transformer oils can extend the service life of transformer oil. 3 0 obj
The properties (or parameters) of transformer oil are: Electrical properties: Dielectric strength, specific resistance, dielectric dissipation factor. Transol GE IEC60296:2012 Uninhibited is an uninhibited oil which is designed to meet Specifications as per IEC 60296:2012. Known for its precise engineering, these plants are manufactured in different specifications to suit the needs of diverse applications. The leading transformer standard specifications are IEC 60296 and ASTM D 3487. HP TRANSFORMER OIL is designed for human safety and free from carcinogenic Poly chlorinated Bi-phenyls (PCB) and Poly aromatic hydrocarbon (PAH). This parameter is the most important parameter for oil filled switches operating in the open air. The rest is distilled to solar oil fractions. 1. The test is not performed for oil during operation. Transformer Oil Specifications. The CMM-CM units use zeolite for purification. The oil filled into the transformer must have low viscosity. stream
TRANSFORMER OIL IEC 296 Class II A Speciality Oils & Lubricants Product Data Sheet SR NO. It also meets IS:335-2018 TYPE II INHIBITED. Technical Specification & Parameters Working Group Members Mr. P. Ramachandran - ABB Ltd. Mr. M. L. Jain - EMCO Ltd. 2 POWER TRANSFORMER - STANDARDISATION MANUAL. To stop this and to insulate and dissipate the heat of the transformer, transformer oil or power transformer oil is used. It is therefore, better to prevent the problem than performing expensive corrective maintenance operations. <>
Solidified oil in low temperatures causes significant resistance to the moving parts of the switch and disrupts arc extinguishing. Used as Diagnostic Tool 1. The specifications should also reference the latest version of the standard. Specification shall supersede these Standards in the event there is a discrepancy: a) IEC 60076 (1993) â Power Transformers b) DIN42500 â Threeâphase oilâimmersed ⦠Transformer Oil Testing is a proven loss prevention technique which should be a part of any condition-based predictive maintenance program. The requirements in the standards are defined with minimum and maximum limits. GENERAL SPECIFICATION. High Vacuum process removes free and soluble water. Ash Content. NYTRO Libra is an uninhibited transformer oil that conforms to IEC 60296 Edition 5.0. Chemical properties: Water content, acidity, sludge content. Transol HGX is an inhibited grade of transformer oil specifically tailored for demanding applications in EHV and UHV Transformers. TEST PARAMETERS TEST METHOD SPECIFICATION Min. <>
This is because it tends to deteriorate over time. Sulfur. Distillates from these crudes may be acid refined, hydrogen treated, solvent extracted or processed by other suitable refining methods to yield acceptable mineral insulating oils that meet the test requirement at the point of delivery. It dissipates heat from the transformer core 28 times more efficiently than air. 2 0 obj

2) High resistivity leading to better insulation values between windings. In more recent years the treatment of transformer oil is the first choice for a cost effective and efficient maintenance program: the increasing cost of new oil, the importance of productivity and equipment downtime, coupled with the environmental benefits of avoiding the transportation of hazardous waste and use of virgin products, are all part of the equation â this applies to medium/high â¦
