The third generation lightning rods are also PDC (Lightning Rod with Starter Device) or ionizing lightning rods, which are made up of autonomous electronic devices that allow accelerating the formation process of the ascending leader.

Unlike the device used by the lightning rods of 2nd. generation, the device of a 3rd generation PDC lightning rod. generation does not require any energy source for its operation, since it only operates in the presence of the electrostatic field that is generated naturally between cloud and ground in the presence of a storm.

It is the DIEC Technology (Impulse Device by Field Excitation).

The operation of this device is through an electronic arrangement that operates at the rate of the variables involved in the formation of lightning, particularly from the accumulation of the electrostatic field between cloud and ground.

The probability of an atmospheric electrical discharge to ground (lightning) is high when the electrostatic field between cloud and ground reaches values between 10 – 20 kV / m.



Some advantages of DIEC Technology are: autonomy in its operation, operation in extreme environmental conditions, safety, operating efficiency, long useful life and compliance with international standards.
