Capacitors control panels

I Overheating shortens the life of a capacitor. Adequate ventilation and cooling facilities, through convection and radiation, must be made available at the place of installation. When housed inside a cubicle, as in a capacitor control panel and in a tier fonnation. sufficient space must be provided between each unit. Adequate... 

Electrical. The plant electrical system is sometimes more important than the steam system. The electrical system consists of the utihty company s entry substation, any ia-plant generating equipment, primary distribution feeders, secondary substations and transformers, final distribution cables, and various items of switch-gear, protective relays, motor starters, motors, lighting control panels, and capacitors to adjust power factor. 

For more than one capacitor bank one RVT for each bank will be necessary for the correct discharge of each bank, (Figure 26.5). An RVT, if provided with an additional star-connected tertiary winding rated for 110 V line to line, can aiso check the discharge condition and its duration and if it meets the design requirements. This can even be monitored remotely through a relay and control panel. 

Consider the control scheme of an auto-control capacitor panel as shown in Figure 23.37. The scheme shows the control voltage as being tapped from the main bus. But for our purpose, we have considered it through a control...
