WhatsAppIf only a capacitor is connected across the relay contacts, the setup is extremely efficient to reduce arcing. However, because of the huge electrical charge stored in the capacitor when the contacts are open, the current flows to the contacts again when they are closed. Over time, this will cause contact welding.
WhatsAppDielectric Absorption. Dielectric absorption is the measurement of a residual charge on a capacitor after discharge, expressed as the percent ratio of the residual voltage to the initial charge voltage. This residual voltage is caused by the relaxation phenomena of polarization, covered in our previous blog post. Just as the polarization ...
WhatsAppWhen voltage is applied current flows through each of the RC circuits. The amount of time required to charge the capacitor is dependant on the CxR values of each RC circuit. Obviously the larger the CxR the longer it will take to charge the capacitor. The amount of current needed to charge the capacitor is determined by the following equation:

WhatsAppHow to Select the Varistor Type To select a good varistor, first, you must make sure the cut-off voltage V C is multiplied with √2. Then, the value must be checked if it is more than 1.5 times the supply voltage. Keep in mind that setting the V C too high is not good as its efficiency will be reduced thus fails to cut off high voltages.
