Surge protection for photovoltaic systems

[2021-08-16 15:04:58]

Overview Indirect lightning strikes are destructive. Anecdotal observations about lightning activity are usually a poor indicator of the level of lightning-induced overvoltage in PV arrays. Indirect lightning strikes can easily damage the sensitive components within PV equipment, which often has a ... Read More

Surge Protection Device Overview

[2021-08-16 14:53:06]

Risks of electrical surges Lightning discharges could contain currents of 200,000A which if struck at or near power transmission lines would generate a significant voltage transient. This voltage transient could cause significant damage to both domestic and commercial electronic equipment. These ... Read More

Low-voltage Power Supply Systems

[2021-08-16 14:13:44]

IEC terminology International standard IEC 60364 distinguishes three families of earthing arrangements, using the two-letter codes TN, TT, and IT. The first letter indicates the connection between earth and the power-supply equipment (generator or transformer): "T" — Direct connection of a point ... Read More
