leakage current calculator
Calculate leakage current using I L =V/R, where V is the voltage across the insulation and R is the insulation resistance.
insulation resistance calculator
Leakage current is computed by dividing the difference between insulation voltage and insulation resistance in ohms E
Formula & Table Summary:
\( I_L = \frac{V}{R} \)
Where: IL = leakage current (A), V = voltage (V), R = resistance (Ω)
insulation leakage current
The Leakage Current Calculator identifies current Leaking out the intended positions The Leakage Current Calculator determines the electric current that escapes unintentional pathways The Leakage Current Calculator detects the electric current that flows away to unintended routes Returning to the formula introduced earlier, leakage current, IL= V / R, where V is voltage and R is the insulation resistance.A Leakage Current Calculator calculates the amount of current going through an unintended pathway, e.g. poor insulation or water in an electrical installation. Leakage current is an important safety related parameter, with overly-high levels of leakage able to lead to electric shock, malfunction of equipment or actuation of residual current devices (RCDs). Leakage current can be most simply computed using the formula known as Ohm s law: the voltage across the insulating layer divided by the insulation resistance.
