How many gallons of oil go in a pole transformer?
Specifications
| kVA | Height Inches (mm) | Oil Gallons (L) |
|---|---|---|
| 10 | 34 (864) | 11 (42) |
| 15 | 36 (914) | 12 (46) |
| 25 | 41 (1040) | 18 (68) |
| 37.5 | 44 (1118) | 29 (110) |
What is transformer oil level?
There is usually a mark on the gauge that indicates the 25°C level, which is the proper oil level at that temperature. Maintaining the proper oil level is extremely important because if the oil level falls below the level of the radiator inlet, flow through the radiator will cease and the transformer will overheat.
How much does transformer oil expand?
Transformer oils also expand at high temperatures and contract at low temperatures. For 1,000 litres of oil and a temperature difference of 50°C, this amounts to 35 litres. Transformers thus have an expansion reservoir.
How much oil does a transformer take?
1-2. 33kV – 400/230V
| Item | Capacity | Oil |
|---|---|---|
| kVA | Liter | |
| 1 | 50 | 165 |
| 2 | 100 | 230 |
| 3 | 160 | 280 |
What oil is used in transformers?
mineral oil
Three basic types of transformer oil used are mineral oil (mostly naphthenic), silicone, and bio-based. Mineral oil based transformer oils dominate the consumption as it has good electrical and cooling properties, and provides cost-effective solution.
What is the name of transformer oil?
Mineral oil
Mineral oil and Synthetic oil are the majorly used transformer oil. These are the petroleum products, like Naphthenic based transformer oil and Paraffinic based transformer oil. Naphthenic based transformer oils are known for their heat distribution, which is one of the main problems with transformer.
What is WTI and OTI in transformer?
The WTI means winding temperature Indicator and OTI means Oil Temperature Indicator which indicates the winding temperature & oil temperature of the transformer and operates the alarm, trip, and cooler control contacts. This instrument operates on the principle of thermal imaging and it is not an actual measurement.
What type of oil is transformer oil?
How much does a 250 kVA transformer weight?
Product Specification
| Brand | Surya |
|---|---|

What is the oil capacity of 100 kVA transformer?
1-2. 33kV – 400/230V
| Item | Capacity | Load loss (75oC) |
|---|---|---|
| kVA | Watt | |
| 1 | 50 | 950 |
| 2 | 100 | 1,550 |
| 3 | 160 | 2,100 |
What is transformer oil name?
Three basic types of transformer oil used are mineral oil (mostly naphthenic), silicone, and bio-based. Mineral oil based transformer oils dominate the consumption as it has good electrical and cooling properties, and provides cost-effective solution.
What type of oil is used in a 300KVA transformer?
AN/AF would mean dry type, first rating natural air cooled, second rating Air forced (fan cooled). A 300kVA oil-filled transformer would contain 300 to 400 gallons of mineral oil. What is being used nowadays is type 2 mineral oil. If you want “high fire point” go with “Envirotemp” soy-based oil, then change the rating to KNAN.
How many kW can a 100 kVA transformer supply?
Presuming a power factor of 0.9, a 100 KW transformer can supply a load of 90 KW maximum theoretically. However, leaving room for load peaks and fluctuations, actual load it can be used for will be 70 \% of this, equal to 63 to 65 KW. Busbar for 100 KVA will carry 100×1.31 (per KVA at 50 Hz)= 131 A at 440 V.
What is the voltage rating of transtransformer?
Transformer has three ratings, Voltage, current and kVA (apparent power). Generally it is adequate to specify voltage rating and either current or kVA rating, because, kVA = 1.731 * Voltage * Current / 1000 for three phase. Current = 11000/Voltage.
What kind of Transformers does Eaton make?
