Switchgear

A Greenwood, Vacuum Switchgear, Institution of Electrical Engineers, 1994. [Pg.380]

Recommended apphcations include transformers, insulators, bushings, wire and cable, generators, motors and switchgear, additives for adhesives, vinyl stabilization, and as viscosity depressants. [Pg.364]

For most plants, 01001 110 distribution systems start at the power company s service point on the plant s property. The choice of an electrical system will depend on many fartors relating to the particular projecl . A wide range of items, from switchgear, transformers, and motor control centers to cabling, earthing, and lighting, are required. Normally, competitive quotations would be obtained to take an estimate beyond the study stage. [Pg.873]

Equipment includes all prefabricated machines, apphances, or systems such as tanks, heat exchangers, pumps, motors, switchgear, and boilers. [Pg.876]

Frequently switchgear is used for motor control, particularly for large high-voltage motors. Switchgear (Fig, 29-6) must be used for motors... [Pg.2488]

The starting of an induction motor does not relate to simple switching alone. It also involves its switchgears to control its starting inrush current, starting torque, or both, and its overload and short-circuit protection. [Pg.71]

The upper limit of the starling torque chosen at 180% appears to be too low and can be raised to, say, 210%. This will also help in reducing the number of steps. Number of steps at 4-6 are preferable to economize on the cost of switchgears, and yet provide a reasonably smooth (free from overshoots) starling torque. [Pg.91]

Since the starting inrush current is kept moderate for all types of drives, it can economize not only on ratings of the switchgears and cables but also on the size of the generator when a captive power is required to feed the load. [Pg.99]
