nowadays, high-voltage circuit breakers have reached such high short-circuit capabilities that testing them under the full rated voltage is generally not possible with direct tests, and they are conducted by using the synthetic test methods. although the phenomena associated with making tests is of particular importance especially in case of load break switches, but making tests are rather disr...

RO-15 This paper focuses on medium voltage switchgear in withdrawable execution, compared to medium voltage switchgear in fixed execution. Looking at the benefits and disadvantages of both executions, and the function the switchgear has to fulfill. Elaborating both executions, investigating accidents and near accidents; analyzing the causes, and studying the possibility of unsafe operation. Giv...

The ultra-high-frequency (UHF) method is used to analyze the insulation condition of electric equipment by detecting the UHF electromagnetic (EM) waves excited by partial discharge (PD). As part of the UHF detection system, the UHF sensor determines the detection system performance in signal extraction and recognition. In this paper, a UHF antenna sensor with the fractal structure for PD detect...

SF6 is the dominating technology for gas insulated switchgear due to its excellent dielectric, thermal and arc quenching properties. Unfortunately, SF6 suffers from a very high global warming potential (GWP). Even though medium voltage switchgear is sealed for life with less than 0.1% emissions per year, the EU has specifically targeted SF6 for replacement in medium voltage switchgear for secon...

In this study a new built-in ultrahigh frequency (UHF) antenna sensor was designed and applied in a high-voltage switchgear for partial discharge (PD) detection. The casing of the switchgear was initially used as the ground plane of the antenna sensor, which integrated the sensor into the high-voltage switchgear. The Koch snowflake patch was adopted as the radiation patch of the antenna to over...

Switchgear and control gear are susceptible to arc problems that arise from slowly developing defects such as partial discharge, arcing, heating due faulty connections. These issues can now be detected monitored using modern technology. This study aims explore the effectiveness of deep learning techniques, specifically 1D-CNN model, LSTM 1D-CNN-LSTM in detecting arcing switchgear. The hybrid mo...

Modern civilization is characterised by a high need for electrical energy. The importance of electricity in daily life has grown to the point that it desirable safeguard power system from damage during fault situations and ensure maximum supply continuity, which necessitates use switchgear. Testing any equipment indicates extent able comply with customer's requirements. In this paper temperatur...

This paper tackles the problem of wire insertion in switchgear assembly according to current regulations. In particular, connections require that label has be oriented facing up order simplify and speed testing maintenance switchgear. The proposed approach exploits a priori knowledge scenario with calibrated RGB camera robotic arm estimate both end pose position. procedure combines several tech...

Gas insulated switchgear (GIS) plays a vital role in high voltage transmission of electrical energy due to its advantages of high reliability and performance, compact in dimensions and outstanding compatibility with the environment. It uses sulphur hexafluoride gas as its insulant and coolant because of its high dielectric strength and excellent arc quenching ability. Gas insulated switchgear i...

This paper develops a novel distributed temperature measurement system based on DSP and DS18B20 digital thermometer. The real-time temperature of each node in the switchgear is obtained by several DS18B20s which are connected on the 1-wire bus together. RS-485 master-slave communication protocol is used to centralize monitoring temperatures of several switchgear cabinets. The system also has th...
