Charge those capacitors to at least 200V for a couple of minutes, then discharge, and repeat the measurement. The leakage current you''re measuring should not occur for properly formed capacitors. Measure the current individually for each capacitor - one of them may be "dead", or perhaps one or more are inserted in reverse.

A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum ...

What is Capacitor Leakage and Why Test for It? Capacitors are two-terminal electronic components that store electric charge. In an ideal capacitor, no current flows between the terminals when a DC voltage is applied. However, real-world capacitors are not ideal. They allow a small amount of current, called leakage current, to flow.

In other words, increasing the capacitance of the Y-capacitors will decrease their impedance at line frequency (50/60Hz depending on where you live) and increase the leakage current as a result. This leakage current is tightly regulated by safety standards. According to IEC 60950, it must never exceed 3.5mA in this type of equipment.
An electrolytic capacitor is a polarized capacitor whose anode is a positive plate where an 94 oxide layer is formed through electrochemical principles that limit the use of reverse voltage.
