Joule Integral

It represents the energy dissipated as heat due to the resistance of the PED during a fault.

The Joule Integral, often written as I2t, is crucial for portable earthing devices because it measures the energy dissipated in the device during a fault condition. This value helps determine the device’s ability to withstand high fault currents without failing.

In practical terms, the Joule integral ensures that the earthing device can handle the thermal and mechanical stresses caused by short-circuit currents. This is essential for maintaining safety and preventing damage to both the device and the electrical system.
