Prototype Of Heater And Humidity Monitoring Device with Dehumidification Method and Auto Backup Feature In 20 KV Cubicle Based on Matlab GUI

Abstract

In the process of distributing electrical energy to customers, especially medium voltage (TM) customers, a cubicle is needed as a switching and metering device installed on a concrete substation owned by PLN. Inside the cubicle there is a component in the form of a heater that functions to heat the cubicle termination space so that the humidity is maintained. This condition is expected to prevent the occurrence of corona effects on the cubicle termination. The design of the temperature and humidity monitoring tool research in this cubicle aims to anticipate the occurrence of corona in the cubicle termination space. The results of the temperature and humidity monitoring tool research in the cubicle are monitored on the MatLab and Telegram applications. The tool works according to the program, where when the temperature and humidity are above the set point of 350°C and 75%, the fan will turn on to stabilize the cubicle termination space, and when the main heater has a problem, the backup heater will work, which gets power from the backup heater obtained from the battery.
