Surge Protection Devices (SPD) for Solar & Sensitive Electronics

Sri Lanka experiences high thunderstorm activity and lightning density, particularly during inter-monsoon seasons. Transient overvoltages from indirect lightning strikes and utility grid switching cause catastrophic damage to modern sensitive electronics, including solar inverters, smart home automation, smart TVs, and inverter air conditioners. Installing correctly rated Surge Protection Devices (SPD) is the primary defense line for […]

Designing and installing a reliable distribution board (DB) requires a clear understanding of low-voltage switchgear. Choosing the correct Miniature Circuit Breakers (MCB) and Residual Current Circuit Breakers (RCCB) prevents dangerous electrical fires, equipment burnout, and lethal shock hazards in residential, commercial, and industrial installations. 1. Understanding MCB Tripping Curves (Type B, C, and D) Miniature […]
