LLPD i20z
The i20z has been designed to ensure the most effective protection from indirect strokes. This device is able to perform as highly effective lightning protection system, providing secure power network operation in 80% of such issues.
What you should know about i20z:
- Only 1 product per pole is required;
- Products are installed with phase alternation (А -> B -> C)
- For the protection of sensitive equipment, such as pole-mounted transformers (PMT), conventional Metal Oxide Arresters are still a must;
- Highest voltage for equipment can be up to 24 kV.
This device will definitely be of great use and will ensure the highest possible reliability, since its performance has been validated by a series of tests at CESI (Milano) according to the test procedure based on the IEC standard.
Operational Principle
The i20z’s works due to the EasyQuench technology.
This innovative operating principle ensures a high ability to discharge excessive energy of an overvoltage in the surrounding atmosphere.
The induced overvoltage will create an electrical power arc between the terminal electrode of an LLPD and the conductor clamp on a line. At first, the arc will be divided by a series of discharge chambers into a series of small arcs, which afterward are quickly quenched when the oscillating current of the grid crosses zero.
