Hello, I am looking for industrial battery capacity tester. The total voltage of 120 cells around 135V. Max discharge current will be 1300ADC. Is there any brand of tester might solve my problem? Thank you. regards,

hello, Fin-tube Heat exchanger internal tube leakage problem was encountered on a large electrical motor. This problem is not easily found exact leakage position when lots of half inch tubes inside the exchanger especially tiny leakage. We use a water pump to check every tube to see if water...

This is a 13.8kv 5MVA DG connected a with a MV bus of a newly built power plant. Our goal is to exam the AVR performance, bearing lubricant system and cooling system during generator full or no load. Consecutively Starting generator at full load, voltage droop..etc. Thank you.

Hello, I'd like to test 5000 kVA generator performace by connecting a load bank. Any one ever purchase it and testing a emergency diesel generator? How much budget I shall prepare for one load bank? Thank you.

Many many thanks to Mr. DRWeig!!

Hello, We are going to coat silver on a bus-bar inter-connection surface for better conduction. Is there any guidances or standards states that how thickness of silver coating layer should be? Thank you. regards,
