High-Voltage Compact Switchgear - Siemens· PDF file6 gas-insulated and air-insulated components. According to CIGRE analyses, gas-insulated components are four times more reliable than air-insu-lated components. By increasing the safety of our product through the separation of gas compartments (e.g. between the circuit breaker and disconnector), we increase availability of switchgear in the market.
Step Down Transformer - Working Principle, Equation, Types ... step-up transformer output is given to a high tension transmission line which transports the power/electricity over the miles. This is done to reduce voltage drop. Once this power reaches its consumption point/ end sub station, then with the help of step-down transformer, it is reduced to the desired value i.e. 220V-240V.
