How is hipot leakage current calculated?
Using the formula I = 377VC, find the leakage current I (in amps) by multiplying the voltage that your hipot test is conducted at (V) by the capacitance you measured between line and ground (C), and multiplying that product by 377. This will give you the anticipated leakage current I (in amps).
What is acceptable leakage current for Hipot test?
Looking at the 120-kΩ rule of thumb, when testing is performed at 1,000 V and the tester is adjusted so that breakdown occurs if the resistance of the product is less than 120 kΩ then the maximum allowable leakage current would be 8.333 mA (1,000 V/120,000 Ω = 8.333 mA).
How is leakage current measured?
The current flowing in the ground conductor is measured by connecting the meter in series with the grounding connection of the device concerned. Leakage current clamp meter is the most popular device used to measure leakage current.
What is the current leakage current limit?
10 μA
The allowable limit for leakage current through an intracardiac connector is 10 μA, which is considered acceptably safe by NFPA and IEC. Higher currents are allowed under certain fault conditions, such as when the line cord grounding conductor is open.
What is leakage current in hipot?
Leakage current is the sum of all ac currents from mains conductors to ground through these resistances and impedances: the insulation resistance, the capacitive reactance across the insulation resistance, the capacitive reactance (impedance) of the Y capacitors.
What is leakage current and mention its range?
Leakage current is the current that flows through the protective ground conductor to ground. In the absence of a grounding connection, it is the current that could flow from any conductive part or the surface of non-conductive parts to ground if a conductive path was available (such as a human body).
What is leakage current in Hipot?
What is high leakage current?
In any electrical installation, some current will flow through the protective ground conductor to ground. This is usually called leakage current. Additionally, longer conductors have a higher capacitance, causing more leakage current.
What is leakage current in high voltage testing?
