Anybody tell me about modbus hex address of l&t trivector meter er300p??I want to read voltage,current,kwh etc via rs485...If anybody have a manual then send on my mail..Brijeshmodi18@gmail.Com
can u please mail me the syllabus for GET exam for damodar valley corporation?
I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
The gauge indicates the number of amps, but what about voltage? How voltage rating (for wire or fuse) determined?
