One of the problems that often arise in distribution systems is load imbalance in meeting electric power needs. If there is a load imbalance in the 3 phase system, the neutral wire in the transformer will be energized. This will cause losses or can be said as unused energy and does not turn into rupiah. For this reason, it is necessary to balance the load of the distribution substations so that the losses that occur do not get bigger. Based on SPLN SE 17: 2014, it is said that the large percentage of load imbalance in distribution substations that can still be tolerated is below 20%, while for distribution substations with an imbalance percentage above 20%, load balancing is necessary. Based on the Transfomer Report of PT. PLN (Persero) ULP Maros, the percentage of load imbalance at the GT.MBS027 substation before load balancing is 44.783% and after load balancing there is a decrease in the percentage of imbalance to 6.867%.Likewise, the total value of energy losses before balancing is 80.802 kWh per day. After the load balancing is done, the amount of lossesdecreases to 2.95 kWh per day. So that you can save 77,852 kWh every day. If converted to a span of 30 days, it can be saved at a powerof 900 kVA of Rp. 3,157,677.12 and at a power of 1300 kVA and above it can be saved of Rp. 3,426,920.47.

To operate the water pump, an electric motor is needed as the driving force. In order for the energy consumption needed to operate an electric motor to be regulated, it is necessary to manage electrical energy at the pump station. One example of a pump station is the local water company (PDAM) Unit Wendit Malang City. This unit consists of 3 pump stations namely Wendit 1, Wendit 2 and Wendit 3. These three parts are supplied by 2 transformers with a capacity of 1110 kVA for Wendit 2 and 1730 kVA for Wendit 1 and 3.From the results of power factor measurements in the three sections, it is known that the power factor value at the Wendit 3 pump station is 0.82. This value does not meet the PLN minimum standard, which is 0.85. To improve the low power factor, two recommendations were given, namely the installation of VSD (Variable Speed Drive) at the PDAM Unit Wendit 1 and 3 pump stations and the installation of a Capasitor Bank at the PDAM Unit Wendit 2 pump station.Based on the analysis, the power factor value PDAM Wendit 3, which was originally 0.82 increased to 0.9. In addition, there are savings in electricity consumption per month of 10.48% at PDAM Unit Wendit 1 and 3 and 28.32% at PDAM Unit Wendit 2.

Transformer 1’s load in Blimbing Substation has increased significantly each year. In 2016 until 2018 the load on Transformer 1 was 33.81%, 43.53%, and 71.75%. The amount of this transformer’s load will affect the hot spot temparature. Hot spot temperature is also affected by environmental temperature. In this study, load curve method was used then followed by calculate the loss life of transformer. From the calculation, known that the higher of hot spot temperature, the higher impact to loss life of transformer too. In 2018, the highest loading data was on November and it was obtained loss life of transformers by 0.649% per month, so it is estimated that this Transformer 1 at Blimbing Substation has a lifespan of 30 years 9 months. According to IEC 60076-7 normal life of transformers with loading under nominal is 20.55 years or 180000 hours. To minimize loss life of transformer or in other words extend the life time of transformer can be done by scheduling maintenance. Scheduling maintenance is the activity which monitoring the main transmission material on scheduled and provided a treatment based on the monitoring results. It can be concluded that the lifespan of Transformer 1 at Blimbing Substation can exceed the specified standard. The one of factors that affect this, is scheduling maintenance.
