In order to avoid an undesirable thing, the electricity network is cut off at<br>the airport terminal which can endanger the safety, comfort and safety of prospective airplane passengers.<br>So, UPS is used as an alternative electrical energy supplier to anticipate sudden power outages while<br>waiting for an emergency generator to be activated (emergenci diesel generator). This report focuses on<br>discussing how long UPS can back up the Airport Terminal load without an emergency generator which is<br>done using the observation method in the field. The results of the observations in the field were found that by<br>using a UPS, namely: 3) The level of efficiency of the AC - AC UPS at the Airport Terminal is 95%, meaning<br>that the more power the source can provide by the Airport Terminal, this allows significant energy savings in<br>every work carried out at the airport, 5) The ability of the UPS to accommodate the transmitter system load,<br>which is for 34.16 minutes, this time is more than enough to switch the power source to the generator set, 6)<br>The UPS loads at the Airport Terminal by 60% (120 kVA is used from 200 kVA), more loads can still be<br>done, 7) UPS rating at the Airport Terminal has more power than the ideal UPS rating (oversizing UPS).<br>This is done to get a longer runtime, if there are additional tools, and not all electronic devices are backed<br>up by UPS</em><em>.</em></p><p><em>&nbsp;</em></p><p>&nbsp;</p> ER -
