In transformer, bushing failure occurs due to (i) transformer vibrations (ii) dielectric losses (ii) partial discharge
Volatility is a statistical measure of the dispersion of returns for a given security or market index. Analysis of a mineral oil sample for volatile compounds provides an indication of whether a fault or significant degradation has occurred.
Here, ω = 500 rad/sec = 2πf. At Resonance condition, ωL = 1/(ωC) L 0.2 H Also at series resonace 1. fr = 1/[2π√(LC)] 2. PF = 1 3. Maximum current 4. Source voltage = voltage across resistor.
