Critical Power Supply Options and Planning of High Availability Supplies

THE WORKSHOP

Our dependence on electricity is growing and even a few seconds or minutes of power disruption has become unthinkable. An unscheduled interruption can cause immense damage and loss of life. While it is impossible to guarantee 100% availability of power at all points in any system, vulnerable sections can be provided with alternative critical power supply equipment to ensure reliable power availability, thereby avoiding the problems of power interruption.

This workshop shows you how to ensure reliable power supply to critical systems using various available options. The solutions can vary from the simple diesel generating set as standby sources to superconducting sag support systems. Nascent technologies like fuel cells have matured and are fast becoming mainstream solutions. Of course, all this comes at a price, which means that the solution must match the actual needs without excessive insurance and thereby optimise investments. This workshop will discuss how to save dollars by finding the right solution to your needs so that you invest just what is needed and where it is needed.

Another major aspect is to ensure that the critical power supply is itself very reliable. This will need suitable redundancies and a well-engineered distribution system so that when the need arises they cut-in and take over the load without any hitches. This workshop will also briefly look at the design issues involved in planning the distribution of critical power by deploying state-of-the art control devices such as static transfer equipment.

If you are responsible for maintaining power availability in your facility, this workshop is something, which you simply cannot afford to miss. And all you need is to just invest half-a-day of your time to gain state of the art know-how from our expert instructor.
