Kaixuan Road, Zhengzhou, China. The assembly may include control and auxiliary devices. For most transformers, Department of Energy rules describe required efficiency levels and specify that transformer efficiency will be optimized at a load level at or near 35%. Switchgear is designed for high voltages (up to 350 kV), while switchboards are designed for voltages below 600 V. Because switchgear is designed for high power handling capabilities, they use devices such as circuit breakers. A switchboard may be as simple assembly of switches and safety devices enclosed in a metal structure and mounted on a wall, or it may be an elaborate free standing structure used to control the distribution of power in a large industrial facility. Learn about basic construction and operation of switchgear, transformers and uninterruptible power supplies. This design makes switchboards smaller, but it also means the breakers are not serviceable and can only be replaced. Switchgear. Thanks. The main difference is the voltage that they are designed to handle. rev2023.1.17.43168. Because a double-conversion UPS continuously generates the output AC, a failure inside the UPS can put the continuity of power to the critical load at risk. These breakers can be removed or replaced while the system is still in operation. "Switchgear" (SWG) and "Switchboards" (SWB) (two different things) are for power distribution, meaning they take in primary or secondary voltages at a site and distribute it to other equipment. DP vs SW BD Usually when you get to the 1200-1600A ranges you are looking at switchboard, but the differences are the physical space requirements switchboards will take up more re-estate and sometimes depending on the size configuration or project specifications may require rear access (not in all cases) as well as front access, where a distribution panels is usually around 12" deep and always front access. "MCC" - motor control centre - refers to a board which includes motor contactors. This process necessitates a delay between the input disturbance and the commencement of replacement power, for detection, realignment of the system and starting the inverter. Its also worth noting that switchgear typically uses a rear compartment for cable terminations. Thus, the term LV switchgear collectively refers to H.R.C. You can either add all your switchboard commands to the Main Switchboard or create secondary switchboards. PDCs have a higher voltage coming in to the transformer (e.g. Switchgear is electrical distribution equipment: it accepts power from a source, routes it to a number of outputs and provides overcurrent protection and control functions. 13.8 kV or 4.16 kV). Transformers are often provided with taps on the secondary coil additional connection points whose output voltage is slightly higher or lower than the nominal voltage, for use in applications where voltages lower or higher than normal chronically occur due to system loading, utility voltage levels or for other reasons. Transformers are not 100% efficient. I think @Andy-aka has a very good answer, I just wanted to follow up on this.
