Abstract

The protection system is essential in the 20 kV distribution network system. The 20 kV equipment control system is supplied from 2 sources: PT (Potential Transformer) and DC voltage supply (Battery). If the protection relay and mechanics do not get a DC voltage supply, it will have an impact on the equipment not being able to trip when there is a disturbance in the network. There is no DC voltage supply due to battery failure or damage. For this reason, it is necessary to operate the tool manually, which results in the normalization process taking longer because it takes time and long distances, so the duration of outages is even greater. In this study, a monitoring system for the battery of the equipment will be made where previously observations were made about the need for this tool. The method used by the tool uses the blynk application as a receiver of direct voltage and temperature measurement reports that are connected to the gsm module. As a microcontroller processes, Arduino Nano commands from intelligent phones, generating a measurement report from the battery. GSM SIM 900 module as a data receiver and sender in the system. This tool is easy to apply to the system because it does not require a sufficient additional voltage source from the battery. The results of this study become a solution for companies to improve their 20 kV. distribution network system.

Abstract

All radios, both transmitting and receiving signals, need an antenna. So the role of the antenna is very important because the antenna can work as a transmitter or receiver, depending on the application of the antenna itself. For the transmitting antenna, it is hoped that it can cover a wide area, so that the receiver can access information in a wide area as well. With the addition of elements with antenna modifications, it will affect the radiance. In this study, the vertical 2 meter band 2 x 5/8 antenna using this phase system has many advantages such as a strong beam pattern in all directions, wide bandwidth and has a large gain and wider coverage area. Then the measurements and calculations of the antenna parameters that have been determined are carried out. From the data obtained at the time of measurement, it was found that the working frequency of the designed antenna was 145.9 MHz. it can be seen that the large amplification of the 2 meter band 2 x 5/8 vertical antenna against the standard 5/8 vertical antenna is 1 dB. The vertical 2 meter band 2 x 5/8 antenna has a bandwidth of 1.4 MHz and an omnidirectional radiation pattern, with a wider coverage area.

Abstract

Interbus transformer (IBT) is transformer that transfer power in different voltage level. Tello Substation has two IBT that change voltage level from 150 kV to 66 kV.  In order to maintain the reliability operation of Tello substation, both IBT must be not allowed to overload. Overload condition could occur if one of the transformers is fault, the normal transformer will be overload.  If an overload condition occurs, the two IBTs may not operate simultaneously. Due to this condition, it is necessary to prevent the occurrence of overload condition by applying overload shedding (OLS). This OLS application can prevent overload on the transformer if one of the transformers out of service due to fault condition. The OLS relay will work when the load on the IBT has reached its setting, by releasing the load on the 66 kV system line according to the OLS scheme as a precautionary step before all transformers trip. This research uses a case study on the Makassar Subsystem, which is one of the Sulbagsel System's electrical systems. The results showed that the amount of load that needed to be removed when implementing the OLS scheme at IBT #3 and IBT #5 31.5 MVA GI Tello was 16.86 MW. The OLS and OCR schemes are coordinated with the OLS setting current at each IBT GI Tello is 302.5 A, while the setting current for OCR at each IBT GI Tello is 330 and  time multiple setting ( tms) is 1.96
