SPECIFICATIONS OPTIONS,STANDARDS WINDINGS ELECTRICAL PERFORMANCE. All generator stators are wound to 2 3 pitch This, Stamford industrial generators meet the requirements of eliminates triplen 3rd 9th 15th harmonics on the. BS EN 60034 and the relevant section of other voltage waveform and is found to be the optimum design. international standards such as BS5000 VDE 0530 for trouble free supply of non linear loads The 2 3 pitch. NEMA MG1 32 IEC34 CSA C22 2 100 AS1359 design avoids excessive neutral currents sometimes seen. Other standards and certifications can be considered on with higher winding pitches when in parallel with the. request mains A fully connected damper winding reduces. oscillations during paralleling This winding with the 2 3.
