In this case, it is worth investing the extra money towards a switchgear setup. Although switchgear and switchboard devices seem similar in function, one of the main differences between these mechanisms is the allowable voltage. Switchboards are used to transmit electricity from one source to another. Switchgear is built to different UL/ANSI standards. The precise coordination of circuit breakers combined with the reduced frequency of power outages will save more money in the long term and result in fewer errors. Eaton uses cookies to help us give you the best experience on our website. SWITCHGEAR. In particular, they need to watch out when terms are used interchangeably. Switchgear should have provision for manual control. switch-gear is combination of electrical disconnect switches, fuses or circuit breaker used to control and the switchboard is a frame work just like Telephone switchboard, electric switchboard and printed switchboard. Buy Panelboard, Switchboard, and Switchgear Lugs . Power-Style™ QED-2 switchboards provide a convenient and economical means of distributing electric power. Hybrid switchgear is a type which combines the components of traditional air-insulated switchgear (AIS) and SF 6 gas-insulated switchgear (GIS) technologies. Power switcher/conducting components like circuit breakers, lightning arresters or fuses which can disconnect power flow when a fault occurs. Switchgear - usually a bank of remote operated breakers and contactors. Discussion Starter • #1 • Apr 24, 2013. Vacuum. Electric switchboards are a device that directs the electricity from one source to another. A switchgear will use low-voltage power circuit breakers that conform to the standards NEMA SG-3 and ANSI C37.20.1, whereas switchboards will employ molded-case circuit breakers and insulated case circuit breakers that adhere to the standards of UL-891 and NEMA PB-2. We make the distinction between switchgear and switchboards meaning one has controls and breakers or contactors, whereas switchboards only have controls and there's no power distribution. Well I am currently working in a switchyard in a power plant so I can give the answer of this question. Panels/frames which hold devices like circuitry indicators and switches to allow the delivery of power or the control of each circuit. Switchgear systems can generally deal with voltages of up to 35000 volts, whilst switchboards , are typically used in commercial applications when energy levels under 600 volts … "Switchgear"? A closer look into things such as their specifications, testing standards and physical design will reveal that these are two very different pieces of equipment that each serve different purposes. They are typically designed to work together in tandem, to provide maximum protection and co-ordination. Switchgear systems can generally deal with voltages of up to 35000 volts, whilst switchboards, are typically used in commercial applications when energy levels under 600 volts are concerned. If there was an accidental power outage, just 15 minutes would be enough to cause some serious financial and operational damage. For example, let’s say that you wanted to determine which of the two to use for a round-the-clock operation such as an hospital or an airport. We're not around right now. Table 1: Switchgear vs. switchboard – comparison of sizes and cost. This document furnished the drawing. While both are dielectric tested at 2200 V, there are some subtle differences within the testing process. MS Excel Spreadsheets (XLS, XLSX) This section is dedicated to tools every electrical engineer can use in daily work. Every panel within the switchboard allows the electricity to be redirected through the use of installed switches. These devices are needed to switch power on and off for transformers, generators, motors, transmission lines and power networks in domestic, commercial and industrial distribution systems. You might be tempted to go for the switchboard because of its lower cost, but there comes the issue of reliability. These spreadsheets developed by enthusiasts will make your job much more easier, alowing you to shorten the time used for endless calculations of power cables, voltage drop, power factor, circuit breakers, capacitors, cable size, power transformers etc. It comes down to including all of the above factors and making a decision based on the information available.
