Singh congratulated the BHEL engineers for designing, developing and successfully manufacturing brushless alternator for M/s. ONGC. He said that the new alternator can cater various load conditions of drilling operation of well during critical drilling, deep drilling and angular drilling.

It has been noticed that during critical conditions due to alternator operation at very low power factor, high reactive power is required. Since oil rig wells are normally located at far remote places, alternators are also to be designed with self start without any field flushing at site. The existing alternators used for oil rig application are rated for 1215 kVA, 1000 RPM and it was felt that the residual voltage generated by the alternator is insufficient for self starting of alternator at site. Now with the development of newly designed brushless alternator of 1430 kVA, 1000 RPM rating all the limitations shall be contained. ([email protected])
