Electrical design for a new leisure centre Essay

Electrical design for a new leisure centre - Essay Example Thirdly, the system design is justifiable because of the quality of lighting that comes from the bulbs and tubes provided. The brightness of the various lights and the colors are friendly to the eyes of the customers in the Leisure centre. The transmission voltage ranges are low, ranging from 2 kV to 35 KV because of the step down and step up transformers within the power system of distribution. Combined centre and the Ice rink areas consume more power units than the rest of the leisure centre. The final justification of the power distribution system design was that the continuous monitoring of the electric meters and circuit breakers. There are primary distribution lines, which carry the medium voltage power to the distribution transformers at the customer premises. Voltage is lowered to the utilization voltage through the transformers to suit the house hold appliances. At this voltage, power is transmitted through the secondary distribution lines. Residential and commercial customers are connected to the secondary distribution line while non-residential buildings and customers demanding larger amounts of power are connected to the primary distribution lines. Leisure centers have a large electrical load than residential buildings; therefore, electrical equipment installed should be more robust and larger. Leisure center’s owners should purchase electricity at large voltages since it comes in a cheaper rate. Owners, in this case, provide and maintain their own step-down transformer mounted in a transformer room inside the building or on a pad outside the room. . This is made to ensure the reduction of volta ges to their required levels. Electricity is therefore transmitted to switchgear, whose role is to distribute electricity efficiently and safely to various electrical closets within the building. Safety features contained in the switchgear include circuit breakers. In this system, circuit breakers allow power disruptions downstream, which may
