We are on the process of planning our new fabrication plant and the we need to have 6pcs. 500KVA transformers. The existing High tension on the area is 30,000V. I am not sure of how much is the capacity of the line in terms of Amperage. Upon calculation, each one of my 500KVA transformer would...
Dear Masters,
I am new to the world of motors, but more or less I can stand the principles. May I ask on how to measure and how to test this big motor that we have for our compressor? Suddenly the start up draws around 500-600A which causes our mains to trip. But when I test the compressor, I...
Hi,
May I ask your technical advise as to how can I test if my exciter stator coil and exciter rotor is still in good shape? I took the resistance reading from the exciter stator and the reading is only 2.5ohms. I understand from my previous readings that normally the stator coil is around...
Guys,
I have this stamford alternator from a MOSA generator. The motor plate says 50Hz but I want to operate to 60Hz. Can I adjust the speed of the engine, jumper the voltage regulator to 60Hz and adjust parameter in the engine control? Can this procedure give me 60Hz? Thanks
Dear Gentlemen,
Anyone with experience in capacitor bank sizing calculations? I have a 280KW Vane Type Compressor and it is to be powered by a 400KVA Cos=.80 Diesel Generator, however problems occured during our test run. Initial Star-to-Delta start up is fine until the pump reaches 11Bars and...
Gentlemen,
Do anybody here uses a High Frequency Generator (combination of a driver motor and a generator)? The mains as described in the motor plate is 380V/50Hz 33A, Exciter Field is 380V 15A, and the output rotor voltage is 135V 200Hz, 22KVA. This high freq. generator is used to power our...
