Moveable shunt welder troubleshooting6/12/2023 ![]() ![]() The measures taken during the operation of the welding equipment showed the following parameters (see Figure 1) //įigure 1 – Improvements due to the real time reactive compensator Improvements All these factors reduced company productivity. Problem #5ĭefective parts caused by welding faults appeared at the end of the manufacturing process when the tubes are bent into shape. ![]() Problem #4Īnnual penalties of 5 kEUR for exceeding the reactive power consumption limit (0.75 power factor). Inability to add equipment for fear that the installation would be overloaded (peak currents when welders were fired were greater that the nominal current of the main circuit breaker).Įxpansion of the installation would thus require substantial investment, either to upgrade the existing installation or to build a new power supply facility. Noise pollution and premature mechanical ageing of equipment caused by vibrations mainly in the transformer and the main switchgear when welding equipment was in operation. Visual and nervous fatigue in personnel, due to the fluctuation in brightness of lamps (flicker) when welding equipment was in operation.
