Electrical Switchboard Contractor Malaysia | New & Maintenance
The electrical supply that powers our everyday life, from domestic to commercial and industrial needs, is a very broad and complex system. From generation to transmission and consumption, electrical energy generated from natural resources or renewable fuels delivered to different end users has to undergo a process involving multiple stages of operations to make it transmissible and usable for various specifications. To facilitate the economic and safe delivery of adequate electricity to all types of electrical equipment, the transmitted power first arrives at an electrical distribution substation, where it is passed through a series of step-down transformers to lower the voltage closer to utilization levels. According to electrical switchboard contractor in Malaysia, this then becomes a standard utility supply that enters our homes, commercial building or an industrial site through a single point, known as the service entrance, which is normally located within an electrical assembly. To systematically regulate and control the raw power input, service entrance electrical distribution equipment such as panelboards, switchboards and switchgear, is employed to perform different duties as a whole to power facilities throughout a building. This range of power distribution equipment generally functions on the basis of power protection against electrical overloads and short circuits while distributing electricity according to the voltage and power rating requirements. Typically for large scale buildings or sites, switchboards, resembling a large single frame or an assembly of panels in the form of a floor-mounted cabinet are used for mounting these overcurrent switches, protective devices, buses and other equipment. Aathaworld is an electrical switchboard contractor based in Malaysia and is readily available for a full range of services including domestic, commercial and industrial power needs.
The Functions and Importance of a Switchboard
A switchboard represents the intermediary between the final point on the utility power distribution system and the beginning of the distribution system for the electrical system of a single facility. Similar to panelboards, the primary function of an electrical switchboard is to control the flow of the power by dividing large blocks of electrical current into smaller independent circuits to be consumed by electrical devices according to their voltage requirements. Each electric panel constituting the switchboard contains switches that redirect electricity and supply power to transformers, panels, and other equipment. In addition to power distribution, an electrical switchboard by electrical switchboard contractor Malaysia is built with functions needed for controlling, monitoring, protecting and recording the functions of each substation; as such it has space and mounting provisions for metering equipment, overcurrent protection, and a means of disconnect for service conductors.
As it has a direct connection to the power, the connection and disconnection of the electricity to the site can be controlled using a circuit breaker or a switch disconnector. A very important component of the switchboard, circuit breakers are also designed for the protection of short circuit and overload; fuses are designed for the same purpose and provide a quicker action but may only be used once when a fault occurs. Protection relays, on the other hand, are used to protect against over voltage, under voltage, phase lost, phase sequence, power surges and earth leakage. As mentioned by electrical switchboard contractor in Malaysia, using indicator lights, voltmeters, ammeters and watt meters, switchboards are also able to monitor electrical status and quality usually for the purpose of energy saving. Certain switchboard models may also offer backup power as a feature and are usually utilized where power interruption is strictly forbidden such as for large data centers and medical facilities. These specialized switchboards may use a generator to manually switch over the power supply or a fully automated system that has an uninterruptable power supply (UPS) supporting the essential circuit while an automatic transfer switches the supply to recharge the UPS battery. To understand better the functionalities of your switchboard, we at Aathaworld, are always prepared to help you gain better insights.
Parts & Components of a Switchboard
A switchboard is made up of multiple elements, with the primary components constituting the frame, bus, overcurrent protective devices, instrumentation, enclosure and exterior covers, in accordance to electrical switchboard contractor Malaysia. The switchboard interior may also house specialized instrumentation, such as meters, transfer switches, transformers and surge protective devices (SPDs). The switchboard frame is a metal skeleton that houses and supports all other components. Also, switchboards usually contain a ser of busbars, that are strips of tin-finished aluminium or silver-finished copper used to transmit high electrical current in a switchboard. These busbars serve as a common connection for multiple circuits and usually connect to a relay or switchgears – which is a combination of electrical disconnects, breakers and fuses used to clear faults and de-energize equipment offered by electrical switchboard contractor in Malaysia. The different configurations of busbars each play a specified role by the standards of respective national bodies. Horizontal busbars are used to distribute power to each switchboard section and vertically aligned bus bars are used to distribute power to the load devices via overcurrent devices. For some medium voltages switchboards, cables are sometimes used instead, which is either cross linked polyethylene or ethylene propylene rubber insulated cable.
In order for electrical switchboard contractor Malaysia to connect and control single or multiple incoming and output sources, controls and monitoring devices such as frequency gauges, synchro-scopes and other instruments are mounted on the switchboard to measure current, voltage, power usage, peak demands and other managing other important power characteristics, ensuring the highest efficiency possible. Protective devices such as the circuit breaker, protection relays and fuses are a vital part of the switchboard that allows them to protect the entire electrical system of the facility from malfunctioning or during power interruptions causing revenue losses. Circuit breakers mainly function to break or make the continuity of the circuit taking into account the probability of certain conditions, and on technical grounds involving the consideration of lower or higher speeds, heavy or low current operation and other opposing influences. On the other hand, fuses protect apparatus and equipment against thermal and dynamic effects of short-circuits; they are generally divided under the two categories – expulsion fuses and current limiting fuses. Electrical switchboard contractor in Malaysia claims that there also exist various types of protection relays that primarily disconnect a faulty system element as immediate as possible using high sensitivity for different substation equipment, such as transformers, incomers, feeder, capacitors, generators and motors.

Inspection & Testing of Switchboards
Switchboards are vital to every business, from food processing to chemical plants, automotive, manufacturing and fabrication productions; it is impossible to perform daily operations efficiently without a centralized electrical system as electricity is the main power source that drives everything around us. As such, upgrade installations of switchboards are essential to ensure handle loads are effectively as these devices would inevitably become overloaded overtime as it draws continuous power from the main power while with the addition of new circuits being installed. The maintenance of switchboard requires a frequent periodic check-up as it could potentially become a hazard when circuits become loose and detach from the mainboard. Moreover statement by electrical switchboard contractor Malaysia, ceramic fuses or old circuit breakers may be too old to still be able to provide the same safety performance as intended, as these devices tend to stick or crack after long periods of usage. Business operators should also be mindful when they take over a new tenancy to replace the existing switchboards as the power requirements for different operations are not the same. It is also important to hire a professional electrical contractor to do the installation as some setup may involve too many setups and overcrowd the wiring if poor workmanship is to be done. To prevent these hazardous issues that could potentially cause switchboard malfunctions, it is best to hire a quality electrical contracting company, such as Aathaworld to install your switchboards and provide regular servicing.
