“…This case indicated that in addition to being caused by wetting intensity, the increasing rates were influenced positively by applied voltages. The rising insulator leakage currents due to rainfall were also implied in [42], [43], [44], and [45] as a low correlation of 0.31 [46] and reciprocal to the applied voltage [47].…”

High-voltage insulators are essential components in overhead transmission and distribution lines. Various environmental factors and probable mounting inclines may influence the performance of insulators. Therefore, it is necessary to continuously and simultaneously investigate these influences using an internet-based data-logging system. Here, the test samples were vertical, thirty-degree, sixty-degree, and horizontal mounting inclinations on 7.5 kV-subjected pin-type silicone rubber (SiR) insulators. The recorded data included 7,917 measurements acquired every five minutes for a month and then analyzed using statistical tools. At midday, the surrounding environmental temperature, illuminance, and ultraviolet (UV) radiation reached their peak values, whereas the humidity reached its lowest value. The air pollution concentration reached its highest levels in the morning, and rain rarely occurred. The insulator leakage currents reached their top values before dawn and their lowest values at midday. Originally, the typical highest leakage current was the vertical mounting insulator, which reached 1.36 up to 2.36 times that of the remaining insulators; the maximum and maximum typical values were 24.27 µA and 4.9 µA, respectively. Increasing illuminance, UV radiation, and temperature influenced the leakage currents to decrease, but the corresponding leakage currents rose as the humidity, air pollution concentration, and rainfall increased. Based on extrapolations of the data, the vertical mounting insulator is the most vulnerable installation for severe air pollution concentrations, reaching a predicted warning condition of 287.2 µg/m 3 . However, the horizontal mounting insulator is the least suitable for rainfall above 16.86 mm. The typical shortest forecasted warning condition is 10.3 years on the thirty-degree mounting insulator.INDEX TERMS Environmental factor, inclination, insulator, leakage current, silicone rubber (SiR).

One of the important components in the high voltage overhead lines placed on the transmission tower is an insulator. Insulators that are installed outdoor will be exposed to the environment directly. Due to environmental conditions and pollutants attached to the surface, leakage currents can flow on the surface of the insulator. Large leakage currents can damage the surface of the insulator and cause losses in the form of heat and even cause flashover. This paper provides an alternative way to prevent early flashover by detecting the severity of the insulator surface based on harmonic measurements of leakage currents. Insulator performance mainly depends on the conductivity of the surface layer being polluted or by generating pollutants via the equivalent salt deposit density (ESDD). The leakage currents were evaluated at different ESDD levels as deposits of very light, light, moderate, and heavy NaCl salt pollution on a 20 kV outdoor polymer insulators. From the experiments, it can be concluded that: i. The leakage current that occurs when the surface of the insulator is very lightly polluted has an unsymmetrical waveform that is distorted and leads to a positive with a large THD; ii. The magnitude of the leakage current with the surface of the insulator is polluted, which leads to greater weight, but the harmonic distortion and THD are getting smaller with the waveform of the leakage current signal leading to a sinusoidal waveform.

Pole-mounted Metering Circuit Breaker (PMCB) is a medium voltage protection device. Problems in the PMCB because operating at medium voltage causes insulation problems. The isolation problem that arises is due to partial discharge. Partial discharge can trigger the risk of flashover. In addition, corona discharge causes corrosion of the conductor, the effect is a failure and disconnection of electricity. This control system aims to maintain the temperature and humidity of the PMCB at the nominal values according to the standard. Based on SPLN D3.021-1:2020, it is known that under normal service conditions, the ambient air temperature does not exceed 40°C and the average temperature for 24 hours does not exceed 35°C and the highest relative humidity is 100% RH. The control system uses an AC voltage controller which is used to control the input voltage of the heater and exhaust fan so that the temperature and humidity can reach nominal operating conditions. The control method used is an artificial neural network (ANN) to find the ignition angle of the AC voltage controller as a TRIAC control. The test results using the ANN control method, system simulation produces a temperature error of 1.029% and humidity error of 2.48% and the hardware system produces a temperature error of 2.364% and humidity error of 8.673% compared to the set point temperature of 35°C and humidity of 50% RH. It can be concluded that the ANN control method can maintain the PMCB temperature and humidity according to standards
