TRANSFORMER FILTRATION_VDPL

TRANSFORMER OIL — TRANSFORMER OIL FILTERATION; FILTRATION OF TRANSFORMER OIL BY STREAM LINE FILTER MACHINE FOR IMPROVING THE INSULATION STRENGTH OF OIL TO THE REQUIRED LEVEL AS PER IS:335. THE SUPPLY.OF THE FILTRATION MACHINE SHALL BE IN VENDOR'S SCOPE. THE VENDOR TO CARRY OUT TESTING OF THE OIL AND SUBMIT THE TEST REPORT.

TRANSFORMER OIL TESTING- — SCOPE OF JOBDRAWING SAMPLES OF TRANSFORMER OIL, TAKING THEM TO APSEB'S/ANY GOVERMENT APPROVED LAB ONCE IN A YEAR THE FOLLOWING TEST SHALL BE CARRIED OUT :1. COLOUR OF THE OIL2. ACIDITY TEST3. TOTAL WATER CONTENT4. DI ELECTRIC DISSIPATION FACTOR5. SLUDGE CONTENT6. FURONIC COMPOUND TEST7. DISSOLVED GAS ANALYSIS. ABOVE TEST REPORTS SHALL BE SUBMITTED TO OFFICE AFTER COMPLETION OF OIL TESTING AND GETTING THE LAB TEST REPORTS HEATING THE GEL TO 150 DEG. C, REPLACING THE SILICA GEL IF NEEDED, TOPPING UP OF CONSERVATOR, RECTIFYING THE TRANSFORMER OIL LEAK BY APPLYING M-SEAL, CHANGING GASKETS, TIGHTENING OF FLANGE BOLTS. CHECKING IR VALUES OF OUTGOING HT PANEL AND TRANSFORMER WINDINGS. ENSURING PROPER FUNCTIONING OF TRANSFORMER TAPINGS AND OBTAINING SATISFACTORY CERTIFICATE OF TEST FROM THE SUB-STATION OF APSEB. IF THE DI-ELECTRIC STRENGTH IS NOT SATISFACTORY, THEN NECESSARY ARRANGEMENTS HAVE TO BE MADE FOR OIL FILTRATION. COST OF SUCH TESTING AT LAB AND OIL FILTRATION TO BE BORNE BY THE PARTY. (IGNORE THE ABOVE DESCRIPTION IN BOLD LETTERS)Transformer oil tests as per IS 1866 & Dissolved Gas Analysis: Transformer oil sample shall be taken from all transformers at Donakonda as per the direction of Engineer-In-Charge. As per latest IS 1866 Standard, the following tests to be carried out for the transformer oil at Authorized / licensed laboratory and issue of test certificates. Contractor shall collect / draw the samples as per aforesaid standard procedure before commencing the Oil Filtration at site. a) Appearance b) Electric Strength ( Break Down Voltage) c) Flash Point d) Sediment & Sludge e) Water content f) Neutralization Value ( Total Acidity) g) Specific Resistance (Resistivity) h) Dielectric Dissipation factor (Tangent Delta) i) Interfacial Tension j) Dissolve Gas Analysis (DGA).
