Motor control center layout
The low-voltage motor control center is a key element in electrical control systems because of the vital operating role they play in controlling motors and production processes. Over the years, MCCs have evolved from cabinets that housed basic electro-mechanical devices such as circuit breakers, contactors and overload relays to centers of automation that may include variable frequency drives, soft starters and programmable controllers. Because failure or malfunction of electrical systems — specifically MCC-housed equipment — can present a serious hazard to personnel and property, it is imperative to comprehend how MCCs are maintained. By shifting from reacting when equipment fails to proactively maintaining machinery through preventive and predictive practices, manufacturers can help mitigate such risks and prevent failures from occurring Fig. Regular maintenance of MCCs occurs in two ways — by inspecting energized or de-energized equipment. One of the most common methods of inspecting energized equipment is infrared thermography. While infrared thermography can be part of an overall preventive or predictive maintenance program, it is not the only method of inspection. Infrared thermography is a non-invasive inspection technology that uses an infrared camera to monitor temperatures and thermal patterns while equipment is running at full load to detect changes in temperature. This is often a telltale sign that equipment is performing out of spec. Used on a wide variety of equipment, including MCCs, this technology helps manufacturers predict equipment failure and plan corrective action before a costly shutdown, equipment damage or personal injury can occur. Infrared also can be used to detect potential electrical fault conditions such as loose or corroded connections hot spotspoor contacts, unbalanced loads, overloading and overheating Fig. Electrical fault conditions can lead to electrical system failures, arcing, equipment fires and high level short-circuits. This inspection method can be difficult, and equipment relatively costly. Safety is another concern because electrical equipment must be scanned during operation with enclosure doors open. If equipment is scanned while enclosure doors are open and the equipment running, personnel may be required to wear personal protective equipment. As an added safety measure, some users install special camera ports on MCC enclosures. Infrared ports allow scanning of devices without requiring open enclosure doors. These cameras can be installed during manufacturing or by the user in the field Fig. The second type of MCC preventive maintenance is inspecting de-energized equipment. This requires more training than visual inspections. To begin, engineeers must follow specific guidelines on de-energizing, isolating and grounding the equipment to be inspected. Structure — Check for moisture or any signs of dampness or drippings inside the MCC. Condensation in conduit and moisture from an outside source is a common cause of MCC failure. Eliminate any source of moisture and seal off conduit, cracks and openings that have allowed or could allow moisture to enter the MCC. Replace damaged or malfunctioning parts. Buses and splice connections — For horizontal to vertical bus connections, some manufacturers do not require servicing for the life of the MCC. For MCCs that permit servicing bus connections, check the integrity of the bus splice connections Fig. Bus splices are normally identified with labels on the MCC structure or referenced in the MCC elevation drawings or user manuals. Wiring and branch circuit protection devices — Assure conductors are not damaged, worn or obstructing moving mechanical parts. Check wires and cables for signs of overheating such as discolored insulation; inspect fuses for discoloration and check for loose power and control connections Fig.

Power distribution systems used in large commercial and industrial applications can be complex. Power may be distributed through switchgears, switchboards, transformers, and panelboards:. Power distributed throughout a commercial or industrial application is used for a variety of applications such as heating, cooling, lighting, and motor-driven machinery. In Basics of Control Components you learned how various control products are used to control the operation of motors. This is accomplished electromechanically using start and stop pushbuttons or other pilot devices wired to control the contactor. The overload relay protects the motor by disconnecting power to the motor when an overload condition exists. Although the overload relay provides protection from overloads, it does not provide short-circuit protection for the wiring supplying power to the motor. For this reason, a circuit breaker or fuses are also used. Typically one motor starter controls one motor. When only a few geographically dispersed AC motors are used, the circuit protection and control components may be located in a panel near the motor. In many commercial and industrial applications, quite a few electric motors are required, and it is often desirable to control some or all of the motors from a central location. The apparatus designed for this function is the motor control center MCC. A combination starter is a single enclosure containing the motor starter, fuses or circuit breaker, and a device for disconnecting power. Other devices associated with the motor, such as pushbuttons and indicator lights may also be included. What I understood is that the only purpose of the MCC is to group all the motor starters together in one place to reduce the cost of using multiple cables for each motor starter and that, in the MCC, each box has the starter and protection devices for the motor. Tanks for the article. However please I need you to send to me a student project on the design and construction of a 2KVA inverter with a pure sinewave output. Hello, can you guys give us a aproximate cost for a motor control center for a water pumping station? Hi Can you please forward me the 4. Search for:. Premium Membership. More Information. Siemens Basics of Energy and Automation Guides. Motor control Power distribution systems used in large commercial and industrial applications can be complex. The most basic type of AC motor control, for example, involves turning the motor on and off. This is often accomplished using a motor starter made up of a contactor and an overload relay. Motor control centers are simply physical groupings of combination starters in one assembly. Related EEP's content with sponsored links.
