An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. Power System Operation and Control. In electric power transmission engineering, high voltage is usually considered any voltage over approximately 35,000 volts. The selection and performance of insulated cables in electrical grids is a vital part of electric power transmission, but is often neglected in favour of a focus on technological construction. R.D.Begamudre, 'Extra High Voltage AC Transmission Engineering', Wiley Eastern Limited, 1986. So, Sub-Stations are important part of power . It is part of a series explaining the options for building out a transmission Supergrid. Circuit breakers are used in transformer substations to The major challenge in UHV power engineering is to provide sufficient insulation to prevent voltage flashovers. EHV AC Undergrounding Electrical Power It will enable readers to make detailed performance comparisons between power transmission systems, which will be valuable for postgraduates, as well as engineers involved in power cable manufacturing or electrical transmission systems. Allan Greenwood, 'Electrical Transients in Power Systems', Wiley Interscience, New York, 2nd edition 1991. This is a classification based on the design of define high voltage circuits as those with more than 1000 V for alternating current and at least 1500 V for direct current, and distinguish it from low voltage (50–1000 V AC or 120–1500 V DC) and extra-low voltage (<50 V AC or <120 V DC) circuits. Direct-current high voltage (dc HV). The new circuit breaker has been designed for a 1.2-megavolt AC transmission line. 69 kV, 115 kV, 138 kV, 161 kV, 230 kV. Reliability Engineering and Application to Power Systems. Ultra-high voltages increase the capacity of power cables, thereby making it possible to transport large amounts of electricity with a relatively small number of overhead lines.
