A new methodology is proposed for the Engineering failure Analysis for capacitors explosions with overloading power transformers condition, the individual and system assessment with an international standard review is developed for a better understanding in the solution proposal.
1. Connect Positive terminal of Voltage Source to positive terminal of the Capacitor. 2 Connect Negative terminal of Voltage source to negative terminal of the Capacitor. Now slowly raise the voltage output of the source . At ' Voltage input to the capacitor > maximum safe operating voltage of capacitor ' , the capacitor will explode.
Capacitors intended for use with d.c. voltage superimposed on the a.c. voltage. About the long-duration voltage the admissible voltage is the highest average value during any period of capacitor energization, the maximum duration is continuous with a voltage factor is 1.00 for power frequency [ 33 ].
In the traditional analysis, the current in a capacitor is increased when it is fed with a high frequency voltage and the harmonics are voltage values at high frequency. To estimate how much the current in the capacitors will increase, it was necessary to measure the amount of harmonics in the voltage wave of the power supply.
According to the measurements and calculations, it is estimated that a reactive power of 100 kVar will be compensated. For each installed motor. That is, 10 banks of 100 kVar capacitors will be placed for each transformer, for the following information: Fig. 4. Case study diagram.
The amplitute of the overvoltage that may be tolerated withour significant deterioration of the capacitor depends on their duration, the number of applications, and the capacitor temperature, it should be assumed that the overvoltage given should not be 1.15 occur 200 times in the life of the capacitor.
