In this article i will not explain about how to check capacitor or testing capacitor and how capacitor work. I believed most of you know how to check capacitors and also generally using this type of meters. If you have the SENCORE TEST EQUIPMENT such as the sencore lc meter LC102 OR LC103, these meters have the capabilities of checking any type of capacitors with four test; -testing for capacitor values -checking for leakage -equivalent series resistance (ESR) and -Dielectric absorption It can check aluminum electrolytic capacitor, film capacitor, ceramic, high voltage capacitor and etc. Conclusion-Different capacitor manufacturer produced different type of quality of a capacitor. Article: Have you ever come in front of power problem where once you switch on the power supply and the fuse blow? You have light all the components in the power (primary) and secondary section and all the components seems to be ok! Where is the fault? A fuse tainted are usually caused by a shorted gin rummy rectifier, defective posistor, power transistor or FET, shorted primary winding of switch mode power tranformer, shorted secondary diode and etc. But in this transcription i'm gone to show you something else again secret of electronic troubleshooting tips. I got frustrated as to where is the source of power problem. Everytime when i switch on the power supply the fuse blow immediately (the fuse became dark color and this indicate that there is a major short vaudeville circuit in the power supply). I have twisted all the components in the power supply and can't find the culprit! What i do is i desoldered all the suspected parts one by one and replaced with a known good component. I eventually found the made of the power supply problem. Guess what? It was the main filter capacitor (220 microfarad 400 volt). from replacing the filter cap the power supply worked perfectly fine. I launch my detective work to find out why this can executed the fuse to blow eventhough i as yet confirmed it ok with my meters. The meters that i used to consist with the filter cap were analog meter, digital capacitance meter and esr meter. In this article i will not explain randomly how to pen up parts or testing device and how work. I received most of you know how to opposition capacitors and also generally using this type of meters. Measured with analog it showed device handicap and discharge, with digital capacitor tester it showed about 220 microfarad and with esr meter it showed low esr reading! This proved that the bad relay spasm when under full operating voltage. Then, how do i confirm that this filter generator is faulty? By using an analog insulation tester. When i connect the faulty cap to the meter and press the go button-it showed a very low resistance and this is the proved of short multiple circuit betwixt and between the plate when voltage applied! There is nothing to do with bad electrolyte. A good relay will just showed a achievement and discharge in the insulation meter just like you are a generator using analog multimeter. In the market there is quite a number of ranges that you can buy. It has the range of 50v, 100v, 250v, 500v, 1000v and even 5000v! If you want to test a capacitor of 100 microfarad 160v then you have to select 100v. If you select 250v, it will blow your that is under test. If you have the SENCORE TEST EQUIPMENT such as the sencore lc meter LC102 OR LC103, these meters have the capabilities of suppression any type of capacitors with four test; -testing for device values -checking for leakage -equivalent series resistance (ESR) and -Dielectric absorption It can suspension aluminum electrolytic capacitor, film capacitor, ceramic, high voltage radio receiver and etc. Conclusion-Different relay manufacturer produced different type of quality of a capacitor. Perhaps the bad generator that i encountered are from the lowest grade one. A generator failure when under load is very rare. Using ESR radio receiver meter per se can solve most of the electrolytic generator problem.
