The oil in OCBs serves two purposes. It insulates between the phases and between the phases and the ground and it provides the medium for the extinguishing of the arc.When electric arc is drawn under oil, the arc vaporizes the oil and creates a large bubble that surrounds the arc. The gas inside the bubble is around 80% hydrogen, which impairs ionization. The decomposition of oil into gas requires energy that comes from the heat generated by the arc. The oil surrounding the bubble conducts the heat away from the arc and ....etc

TRANSFORMER PROTECTION WITH SMS ALERT
ABSTRACT
The system employs a microcontroller to collect all transformer parameters like voltage, temperature, oil level etc. are and are then analyzed in the microcontroller. During analysis it observes for any abnormalities in measured values and if abnormalities occur it disconnects the load to protect the transformer and load devices.
GSM (Global System for Mobile communications: originally from Group Special Mobile) is the most popular standard for mob ....etc

Oil Circuit Breaker
a high-voltage AC electrical switch whose main contacts are located in a space filled with mineral (transformer) oil. Upon interruption of the electric circuit, an electric arc forms between the contacts of the circuit breaker. Because of the high temperature of the arc the oil is evaporated rapidly and oil vapors are partially decomposed, liberating ethylene, methane, and other gases. A gas bubble is formed in the arcing zone; the pressure in the bubble may be as high as several dozen meganewtons per sq m. The arc is then ....etc
