The Transmission Substation
This substation uses large transformers to convert or "step up" the generator''s voltage to extremely high voltages for long-distance transmission on the transmission grid. Typical voltages for long distance transmission are in the

So to display the sub-units of the Henry we would use as an example: 1mH = 1 milli-Henry – which is equal to one thousandths (1/1000) of an Henry.; 100μH = 100 micro-Henries – which is equal to 100 millionth''s (1/1,000,000) of a
6 FAQs about [When does the high voltage switch store energy ]
Why do we use high voltage switchgear?
Its efficiency is derived from the high voltage. The main reason for using a high-voltage switchgear system is enhanced efficiency. When the power is transmitted at a high voltage, the higher voltage results in a lower current required for the same amount of energy to be distributed.
Why is a high-voltage switchgear electrical system more efficient?
A high-voltage switchgear electrical system is more efficient than the typical apparatus. Its efficiency is derived from the high voltage. The main reason for using a high-voltage switchgear system is enhanced efficiency.
What happens if a voltage is high?
When the power is transmitted at a high voltage, the higher voltage results in a lower current required for the same amount of energy to be distributed. The lower current requires smaller conductors, which are easier to install, less expensive, and more efficient to distribute over longer distances.
What happens when electrical current flows through switchgear?
When electrical current flows through switchgear, it is controlled by the circuit breakers, disconnect switches, and fuses. When there is an overload or short circuit in the electrical circuit, the circuit breakers trip, interrupting the flow of current and preventing damage to the equipment or personnel. There are three main switchgear types:
What is a high-voltage MEMS plasma switch?
A high-voltage MEMS plasma switch is developed to control a buck converter transferring the energy between the buffer and the final reservoir. The switch control law is provided with an automatic narrow hysteresis loop, in order to hold the voltage across the buffer capacitor always oscillating between two high voltage levels.
How do you store electrical energy in a low-voltage circuit?
To store the generated electrical energy in order to power low-voltage electronics, a specific conditioning circuit should include an AC-to-DC converter and a DC stabilization module. Basic conditioning strategies are based on full-wave (FW) or half-wave (HW) diode-bridge rectifiers, which charge a large capacitor to a DC voltage.
