| Item | Capacity | Oil |
|---|---|---|
| kVA | Liter | |
| 8 | 630 | 550 |
| 9 | 800 | 700 |
| 10 | 1,000 | 750 |
Which oil is used in transformer insulation?
Naphthenic mineral oil
Naphthenic mineral oil has long been the most preferred insulating liquid for power transformer insulation because it has a good pouring point at low temperatures, good thermal cooling capacity, low cost, high efficiency and availability on the transformers market [1, 2, 3, 7].
What is 750 kva transformer?

How do you test insulation resistance on a transformer?
IR Value Measurement (Conductor to Earth Insulation)
- Connect conductor under test to the Line terminal of the megger.
- Connect earth terminal of the megger to the earth.
- Rotate the handle of megger or press push button of megger. The reading of meter will show the insulation resistance of the conductors.
How many amps can a 750 kva transformer handle?

What is Rtcc panel?
RTCC stands for Remote Tap Changer Control. RTCC panel used to control the transformer output voltage by controlling the OLTC unit of the transformer. OLTC controls the winding tap position of the Transformer and it resulted in the output voltage also changes.

What is the physical basis of a transformer?
The physical basis of a transformer is mutual induction between two circuits linked by a common magnetic flux. In its simplest form, it consists of two inductive coils which are electrically separated but magnetically linked through a path of low reluctance as shown in Fig. 32.1.
