Transformer 3 of Pesanggaran Substation obtains additional power plants with a maximum power of 60 MW. Power generation is used to supply the load of feeders in Substation of Pesanggaran and also channeled to 150 kV transmission system at Substation of Pesanggaran through Transformator 3 to Substation of Nusa Dua to assist power supply at Nusa Dua Substation. If there is a feeders interruption in the Substation of Pesanggaran which causes the load of feeders to be disconnected, then the power from the generator that is flowed to the 150 kV system increases. Thus the Transformer 3 works heavier, resulting in the current and temperature of the transformer also increased. Increased temperatures in the transformer for long periods can result in damage and reduced lifetime of the transformer. From the problems then calculation of current and working time OGS and OCR as the Transformer 3 safety system. The result of calculation of OGS setting of phase1 is 1600 A with setting work time of 2 seconds, phase 2 is 1700 A with setting working time of 1,5 seconds and stage 3 of 1800 A with setting work time of 1 second. The OGS relay characteristic is definite. For OCR at 150 kV side, the current setting is 277 A and setting time is 1.36 seconds, while OCR setting at 20 kV side is obtained by setting current of 2078.4 A and setting time of 1.18 seconds with OCR Relay characteristic used is inverse.

Energy needs from year to year has increased along with the increase of population,economic growth, and high energy consumption. Until now, the world still depends on fossilfuels, this causes the depletion of oil availability and also causes air pollution. As a developingcountry, many industries are running around us and also many new industries are growingevery day. Every industry generally has an exhaust fan to maintain the temperature of the workspace. This exhaust fan works to remove air from the inside out. This research uses exhaustfan exhaust by using a 2-blade turbine and the addition of a wind tunnel, which will latercompare the output between using a wind tunnel and without using a wind tunnel. In theresearch the use of exhaust fan exhaust air without using a wind tunnel to get an output of0,30625W while with the addition of wind tunnel output increased by 8,25% to 0,76176W.

The transmission line of 150 kV between GIS (Gas Insulated Switchgear) Bandara Ngurah Rai and GI Nusa Dua needs to be concerned further due to the high number of VIP customers supplied by the GIS Bandara Ngurah Rai. The location of transmission line of GIS Bandara Ngurah Rai with GI Nusa Dua is also located in the southern area of Bali in which according to the data of BMKG in 2018, it was recorded that 15.000-30.000 lightning strike occurred in the southern area of Bali. One of the devices used to protect the equipment from lightning surge is lightning arrester. Lightning arrester which is used in the network of GIS Bandara Ngurah Rai to GI Nusa Dua is placed on Cable head 60. The transmission line of GIS Bandara Ngurah Rai with GI Nusa Dua is connected by an overhead line of 8.5 km and an underground cable of 2.02 km, which is connected by terminating on Cable head 60. The distance between the Airport GIS transformer and the lightning arrester is 2.02 km, therefore it needs to be studied further in order to find out whether the protection generated by the lightning arrester has been optimal or not. The result showed that the arrester with an installation distance of 2020 meters from the transformer is still able to cut the lightning surges by producing the sparkover voltage value of 605.12 kv. Accordingly, the result of sparkover voltage exceeds the sparkover voltage of the arrester in the number of 577kv, however the voltage is still within the tolerance range of the sparkover voltage of the arrester.

Karangasem Regency, especially in Kubu Subdistrict, Tianyar Tengah Village, Banjar BukitLambuh, is an area that still lacks clean water, so that villagers still rely on purchasing clean waterthrough tank trucks at high prices. Around Banjar Bukit Lambuh, there is a 20 kWp Central TianyarPLTS which has been abandoned since 2016 due to the absence of regional companies that manageand maintain the PLTS so that some components of the PLTS are damaged. The abandonment of the20 kWp PLTS makes the Bali Provincial Manpower and Energy Department (ESDM) Department planto transfer the function of PLTS as a source of electricity for water pumps that lift water fromreservoirs with a water capacity of 72,000 liters to a 30,000 liter water reservoir which is near thePLTS to meet the water needs of residents in the Middle Tianyar Village Banjar Bukit Lambuh. Theselected water pump type Lorentz PS2-4000 C-SJ3-32 submersible DC with a total head of 108.6meters and a pipe length of 1,640 meters and requires power of 2.96 kW supplied from PLTS 20 kWpTianyar Tengah with a cable length of 1,640 meters and voltage drop of 8,183 volts, so that the pumpcan operate for 7 hours with 4.2 m3 / h water discharge producing 29,400 liters of water that can meetthe water needs of residents of Banjar Bukit Lambuh Village by 23,328 liters per day.

The Sanda feeder is supplied by Antosari Substation through transformer unit II and ithas 3 reclosers, they are pempatan recloser,bangsing recloser and palisan recloser. Based onthe 2017 disturbance fault recapitulation data from PT PLN (Persero) Bali, it has been phasephaseand 1-phase ground short circuit in Sanda feeders almost every month. One of theproblems that often occurs in Sanda Feeders is when a phase-phase and 1-phase ground faultoccurs at the end of the feeder network and causes simultaneous trips to the recloser at thebase of feeder network, causing the Sanda feeder relay to blackout. This shows the systemneed to analyze the evaluation of the coordination settings for the OCR and GFR protectionsystem on the recloser and Sanda Feeder relays to minimize disturbances so as to improveservice continuity. The analysis and simuation results represent that, the existing settingconditions of OCR and GFR has coincide coordination curves and the grading time is still below0.3 seconds. The calculation and simulation of OCR and GFR that are carried out show that theprotection system works selectively in the absence of coincide coordinating curves and a timegrading value above 0.3 seconds according to the IEC 60255 standard.
