difference between switchgear and switchboard

Below is a picture of switchyard where I work. The main role of the switchboard is to allow the incoming electric power to be divided into smaller independent circuits according to their current requirements. It is a good one! Power control components such as protective relays, control panels, current transformers and other devices to monitor, protect and control the power conduction components and the electrical equipment. As nouns the difference between panel and switchboard is that panel is a (usually) rectangular section of a surface, or of a covering or of a wall, fence etc; (architecture) a sunken compartment with raised margins, moulded or otherwise, as in ceilings, wainscotings, etc while switchboard is (telecommunications) the electronic panel that is used to direct telephone calls to the desired recipient. lighting loads, sockets etc. The switchgears are either outdoor or indoor. I agrree with Jacques Schonek comment too. Tell us what you're thinking... we care about your opinion! The switchgear devices are mechanisms that enable the connection and disconnection of the electrical power to other circuits and loads. I am familiar with both European and North American, and when i see Switchgear, Switchboards etc, I read in context. Switchgear is typically more expensive than the individually mounted switchboards, but it may have certain features that preclude the use of any other equipment. The are labelled as Form 1, Form 2, Form 3 and Form 4. That is not an NEC recognized designation, though. A switchgear is a collection of switching devices needed to service low, medium or... Switchgears consist of two main components:. These are often seen in small- and medium-size commercial or institutional facilities. These differences include configurations, components, reliability, standards and applications. The figure 1 can’t be a medium voltage switchgear. The best way to have an world wide homologation is to refer to IEC (International Electrotechnical Commission) and its IEV (International Electrotechnical Vocabulary). Forms 2, 3 and 4 are further broken down into Form 2a, 2b, 3a, 3b, 4a and 4b. Switchgear - usually a bank of remote operated breakers and contactors. Cable connections are made in the front of the board. Presentado por Cristobal Gómez, Ingeniero de Especificación. With a switchboard, a technician … In such a discussion, it could be useful to start from the official definition given by IEC: Switchboard: part of a manual or manually supervised exchange at which the interconnection of circuits is manually controlled, Switchgear: a general term covering switching devices and their combination with associated control, measuring, protective and regulating equipment, also assemblies of such devices and equipment with associated interconnections, accessories, enclosures and supporting structures, intended in principle for use in connection with generation, transmission, distribution and conversion of electric energy. Each panel contains switches to allow electricity to be redirected. Suggestion Buy Panelboard, Switchboard, and Switchgear Lugs . The electrical distribution equipment is designed to redirect and control the flow of electricity from one or multiple sources, to several different sections or loads. 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. More details. thanks for the article, in indonesia generally we assume switchgear is for medium voltage, while switchboard for low voltage. What is the difference between switch gear and control gear ?.. … 20% off code for Pro Plan: EEP2020. "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. I agree with the comment given by Jacques Schonek. Electric switchboards are a device that directs the electricity from one source to another. Switchgear has a very specific UL and ANSI definition and should not be confused with switchboards or panelboards. The switchboards are generally for voltages less than 600 volts, while the switchgear systems are designed for higher voltages reaching up to 350 KV. Switchboards take incoming power and distribute it to smaller loads. The circuit breakers as well as over current protection devices for each of the sections are selected according to the load current. Switchgear is often designed for higher voltages. Thanks for posting the article to help me learn and understand a little bit better. Looking forward to read all your comments and remarks in the comment section below! My friend was telling me that there was a problem with his switchgear and I didn’t really understand what he was talking about. Since the two have different functions and capabilities, they are suited for different types of installations or at different stages of an electrical network. if you consider as a switchgear a low voltage unit, what is then medium voltage unit or what is an MCC? There are many technical term and word missused in English an other lenguages like in Spanish speqking countries. There are major differences in the hardware and design of the two systems. You are confusing the terms, when you write switchgear must be switchboard and vice versa. Other than in distribution and transmission networks, the switchgears are used in residential, commercial, industrial circuits. The breakers are directly connected to the bus and not typically exposed to each other within the entire enclosure. The switchboard and switchgear are two important systems that control how power is delivered to electrical circuits. Depending on the location in which the equipment will be installed, there are arguably situations in which one is better than the other. The switchboard consists of mechanisms such as those in the switchgear system. The switchgears have robust constructions, are more flexible and reliable. Switchboards require less room as they work primarily through front access. One of the major differences between switchboards and switchgear is the type of breakers that are used. It is composed of an assembly of panels. Your building will be connected to the local electricity supply via a building incomer which will normally provide the supplies to the main HV/LV (high voltage/low voltage) switchboard in your building. In its most basic form, a low-voltage switchboard is a common grouping of fixed, “sealed type” circuit breakers in a common enclosure. Terminology continues to be confusing to the reader.
