The capability of transmission lines varies with the square of the voltage. The capability is also dependent on the thermal limits of the conductor, on the allowable voltage drop, on reliability, and on the stability requirements for maintaining synchronism among the machines of the system. Most of these factors are dependent on line length.

High-voltage power system components usually power system components overhead lines supported by steel, cement, or wood structures. At present, the application of underground transmission is negligible in terms of the total length of transmission lines.

Components of Electrical Power Systems

This is primarily because of the much higher investment, as well as repair and maintenance, power system components of underground compared to overhead transmission. The use of underground cables is mostly confined to heavily populated urban areas or wide bodies of water. The first step down of voltage from transmission levels is at the bulk-power substation, where the reduction is to a range of Some industrial customers may be supplied at these voltage levels.

The next step down in voltage is at the distribution substation, where the voltage on the transmission lines leaving the substation ranges from 4 to power system components This is the primary distribution system. A very popular voltage at this level is 12 kV line-to-line.

Most industrial loads are fed from the primary system, which also supplies the distribution transformers providing secondary voltages over single-phase, three-wire circuits for residential use. Here the voltage is V between two wires and V between each of these and the third wire, which is grounded.

Electrical Load Characteristics The ultimate objective of any power system is to deliver electrical energy to the consumer safely, reliably, economically, and with good quality. Operation of the power system requires that proper attention is given power system components the safety not only of the utility personnel but also of the general public.

At the consumer load centers, electrical energy is power system components to other more desirable and useful forms of energy.

This implies that the supply of electricity should be available where, when, and in whatever amount the consumer requires. The quality of the supplied electrical power system components is partially dependent on energy usage by the consumers. Power system components there is a high demand on the limited capabilities of the power system, the voltage may deviate from its acceptable levels.

The sub-transmission voltage level ranges from 90 to KV.

The sub-transmission system directly serves some large industries. The capacitor and reactor are located in the substations for maintaining the transmission line voltage.

Electric power system

The operation of the sub-transmission system is similar to that of a distribution system. Its differ from a distribution system in the following manner. A sub-transmission system has power system components higher voltage level than a distribution system.
