leakage current can be determine through the use of clampmeter or ohm-meter. leakage current can be determine through the use of clampmeter or ohm-meter.
You can use Ohm's law (E=IR) to get this answer. Disconnect power to the circuit, and measure the leakage path's resistance (This is usually the rated resistance of the insulating material...you will need a M-ohmmeter to measure insulation resistance, as it will be MUCH higher than a standard ohmmeter can measure). Then rework the formula to solve for current: I=E/R or simply: divide voltage by resistance. You can also use an inductive current clamp as mentioned above. This clamp measures electrical current by measuring the electromagnetic field strength of the current flowing through the wire.
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .

1. The capacitor has Lead resistance in series with the capacitor2. Since most capacitor use Dielectric and they have a leakage resistance and it is parallel to the Ideal Capacitor.
Leakage resistance in any circuit is resistance less than infinity where it is not expected, such as across an insulator. In the ideal sense, all circuits have leakage resistance because no insulator is perfect, but we usually ignore this except in special situations because it does not normally matter in real applications. In an RC circuit, leakage resistance would most typically be across the capacitor.
A capacitor that is suddenly connected to a battery will charge to the battery voltage. The time to do this is dependent on the current capacity of the battery and wiring, and the capacitance of the capacitor. This represents an instantaneous short circuit, which lasts for a (usually) very short time - but damage could be done if there was no resistance. A charged capacitor that is suddenly disconnected from a battery will hold that voltage. The length of time it will hold is dependent on how much leakage current there is.

A capacitor with low leakage typically refers to a ceramic capacitor, specifically those with C0G or NPO dielectric material. These types of capacitors have very low leakage currents due to their stable and non-polarized characteristics.

yes
if the source is switched off there will be leakage slowly discharging the capacitor

infact what happens in practical capacitor action that air in between parallel plates of that capacitor it acts as a dielectric medium and leakage current starts flowing, that leakage curent is then being bypassed through a conductance in parallel with the capacitor.But in the ideal case that leakage current can't flow due to infinite resistance which can not be provided practically.
