    The arc radiates heat and begin to heat the SF6 gas in fixed thermal volume, which increases the gas pressure inside the thermal volume. At the same time the Puffer pressure increases and released through the over pressure relief valve. Hence there is no need for high operating energy to over come the compression of SF6 gas.
