    power factor issue

    thanks for your inputs. but at the end of the day, the Govt people keep penalising my small start up intentions and heavy penalty levied on me. The power factor of 0.1 , means i utilise a current on a average of 5 to 8 amps, but with the VAR, iT SEEMS they pump in 150 amps. so, how i effectivly...

    How to correct pin joint to fixed joint Concrete PEDESTAL TO BASEPLATE

    Dear Jayrod12, Thanks for the reply. My question, was by rotating the location of the anchor bolts by 90 deg. the constraints would take moment loads. Just by regrouting. Would it yield the desired need of taking care of the moment load. Yes, the bolts dia are 20mm for now. the pedestal size...

    TRANSFORMER POWER SUPPLY OUTPUT FREQUENCY HIGH AND ERRATIC

    FOR A sTATIC IONISERR WITH ac ionisation, the TRANSFORMER WITH HIGH VOLTAGE LOW AMP. WAS MADE. bUT THE Supplier transformer fluctuates and shows up frequencies of 00 to 400 hz. Not sure what might be the issue. The voltages and ampere levels are decent. But, the sinusoidal freuency is not good...

    AREA MOMENT OF INERTIA OF WELDED bEAM

    i am working on a cost effective ramp to carry a load of 100kgs on very light weighted structure. I hit a road block now, on a frame horisontal and 415mm wide X 650mmm long. with a thickness of 20mm. This frame should be below a kg weight but carry a static load capacity of 80 to 100kgs. With an...
