Rancang Bangun Automatic Transfer Switch (ATS) PLN - Genset 3 Phasa 10 kVA

In certain places such as the center of trade, hospitality, banking, hospitals and industry require electrical energy in a continuous and reliable in carrying out the function and production. Therefore generator set (genset) is used as the source of electrical energy backup to support the main electrical energy from PLN. As a control when the generator takes over supply of electrical power to the load or vice versa, a system or tool called automatic transfer switch (ATS) is used. ATS that is made here based on magnetic contactor as main conponent and magnetic relay as control component. In accordance with the name, ATS is able to work automatically to turn on the genset when PLN power goes out as well as directly to supply the load and to turn off the genset when PLN comes back online and restore the supply of the load to PLN. When outages occurs, then the electrical energy supply to the load will be terminated for three seconds (during the process of starting the genset), thus also when the PLN comes back online, then the outage occurs for three seconds (during the return process of electrical energy supply from genset to PLN).
