how to get bearing & winding temperature of an induction motor?
why odd number of lines used for scanning
What happen if we apply square wave or traiangular waveform voltage to the transformer primary winding instead of sinusoidal wave?
There are two chlorination tonners both are connected to two pressure swithes and the pressure switch is connected to SOV which operates the valve to changeover the tonner selection i.e if pressure one tonner goes low the other tonner should come in line if it is inautomatic selection design a circuit using relays ?
Transmission voltage is kept 11KV,33KV,66KV,132KV,220KV due to form factor. What happen to 400KV and 765KV transmission voltage?
new 90kw motor installed so how I purchased cable ,fuse,etc please give me technic for cable selected why always capacitor delta connection
