Abstract

Electrical loads have resistive, inductive and capacitive characteristics. This characteristic will have an impact on the electrical system, namely the power factor. The power factor value is limited from 0 to 1. If the power factor value is close to 1 (high active power), the electrical system will be better, and vice versa, if the power factor is low, it is close to 0 (high reactive power), so that less electrical power can be utilized from the amount of power looks the same. When the electrical system has a low power factor (large reactive power) it will affect the decrease in power quality and increase the use of electric power. In problem identification, it is found that there is a lot of use of electro motors or 3 phase electric motors which produce inductive loads and affect the power factor or cos phi. PLN has determined the minimum value of the power factor is 0.8. If the power factor is below 0.8 then consumers or factories that use it will be fined by PLN. The need for a capacitor bank that is used at a power capacity of 105 kVA with a cos phi of 0.9 is 22.33 kVAR.

Abstract

The increasing demand for electrical energy, the performance of the equipment in the power plant also increases. Transformer is a tool that feels the impact, namely the increasing temperature of the conductor inside the transformer. To find out the indications of failure in the transformer, we can test one type of insulation on the transformer, namely transformer oil, by testing the Dissolved Gass Analysis and testing the breakdown voltage (Breakdown Voltage). After testing the DGA, the TDCG results are analyzed, whether they are in accordance with the IEEE 1991 Standard. And the Breakdown Voltage is in accordance with the IEC 60156 Standard (SPLN). Test results in November 2021, the TDCG value is in condition 2 referring to the IEEE 1991 standard, where in conditions This requires vigilance and must determine the allowable loading. And after testing the breakdown voltage of the transformer oil, it is known that the breakdown voltage condition is ≤ 30 kV, if it is adjusted to IEC 60156 standards, the breakdown voltage value of the oil starts to be LOW/NOT GOOD. When the results of the Dissolved Gas Analysis and Break Down Voltage tests are not in accordance with the Standards, it results in a decrease in insulation resistance which causes not optimal power to be supplied to customers. Therefore, to maintain the performance or life time of the transformer itself, maintenance is needed. Treating oil is an effort that must be made to maintain the insulation resistance according to the permitted standards and the transformer can operate optimally.

Abstract

ABSTRACT The electrical system is an important component in modern infrastructure, because almost all devices used in human activities today use electricity as a resource. To maintain the continuity of these activities, a system is needed that can monitor electrical conditions in real time in order to prevent bigger problems from occurring in the electrical system. This monitoring system uses the PZEM-004T to measure voltage, current, and frequency. NodeMCU ESP8266 to help display data such as, Voltage, Current, and Frequency on I2C and Blynk LCDs. I2C LCD to display Voltage, Current and Frequency. And Blynk to display Voltage, Current and Frequency. The results of the tests that have been carried out have an average error value of 0.0012% for voltage and 0.28% for current. Where the average error value in each test is below the tolerance value stated in the PZEM-004T sensor specifications, which is 0.5%. Keywords: Monitoring, Voltage, Current, Frequency, Blynk.
