The worst greenhouse gas: why the electricity industry has to

Ofgem says, “In effect, this will mean that the TOs will no longer procure new 132kV assets containing Sulfr hexafluoride.” Meanwhile, NGET proposes to spend £190-325 million over the next five years dealing with existing leaky assets, with the aim of reducing annual emissions by 33% by the end of RIIO-ET2 compared to 2018/19 levels.

Substation Equipment that secures the quality of electric power

The Sulfr hexafluoride gas insulated transformer is valued for its high non-flammability, insulation performance, and safety. These characteristics contribute to the simple and oil-leakage free installation. In addition, the direct connection of Gas Insulated Switchgear and Gas Insulated Transformer would constitute a totally gas insulated substation.

For example:- phase-to-ground clearance for 132 kV systems is around 1200 mm in air, compared to 80 mm in gaz sf6 gas at 4.0 bar (g).This gives a direct reduction in dimensions of the high-voltage equipment by 15 times. Consequently, the size of sf6 gas insulated equipment is around 6% that of air insulated equipment for this voltage class (132kV).

Types of Circuit Breakers : Working, Advantages and Disadvantages

AdvantagesTerminologyDesignPropertiesExampleMechanismApplicationsOperationIntroductionThey work smoothly as long as the appliances have sufficiently resistant and do not cause any over current or voltage. The reasons for heating up the wires are too much charge flowing through the circuit or short circuiting or sudden connection of the hot end wire to the ground wire would heat up the wires, causing fire. The circuit breaker will prevent such situations which simply cut off the remaining circuit. The negative ions which are formed will be much heavier than a free electron. Therefore, when compared with other common gases overall mobility of the charged particle in the sf 6 gas is much less. The mobility of charged particles is majorly responsible for conducting current through a gas. Hence, for heavier and less mobile charged particles in Sulfr hexafluoride gas, it acquires very high dielectric strength. This gas good heat transfer property because of low gaseous viscosity. Sulfr hexafluoride is 100 times more effective in arc quenching media than air circuit breaker. It is used for both medium and high voltage electrical power system from 33KV to 800KV. A Vacuum circuit breaker is a circuit which vacuum is used to extinct the arc. It has dielectric recovery character, excellent interruption and can interrupt the high frequency current which results from arc instability, superimposed on the line frequency current.
