In automotive industries the welding application is very fast and critical. The welding speed influences the characteristic of the reactive power drawn from the grid. |
|
The Datar Weld Master incorporates linear as well as cyclic logic to measure and control the kVAr requirement of the welding and other equipments and co-ordinates accurately the injection of reactive power. |
|
The measurements of all relevant electrical parameters are carried out on a real time basis by the FFT method as well as conventional method by simple time integration. The kVArh recorded is separately accumulated/neutralized depending upon the historical performance within 40-60 milliseconds. The software ensures that all the Banks of capacitors are equitably utilized while choosing the combination on cycle to cycle basis. |
|
The controller and the measurement module employ high speed data acquisition and analysis hardware and software. The software has various interlocks to ensure utmost safety and invokes error sub-routines in case of faults which need attention. |
|
The controller, the software and the power electronics hardware are all synchronized using special procedures and deliver optimum performances. |
