Residential and Commercial Complex

Applications

Lightning and Over-voltage protection for residential and commercial structures

Residential and commercial high rises now are complex architectural wonders with numerous electric and electronic equipment. Large appliances such as washing machines or refrigerators have a higher electromagnetic immunity as compared to computers, security alarm, fire alarm, access systems and TV sets. Complexes with automation services using robotics are even more exposed to damage during lightning events.

Shut down of electronics in commercial complexes can be a disaster in terms of safety of people and revenue as a whole. In many of these premises there are internal computer networks connecting even equipment placed inside different buildings. Data lines and their connected equipment are designed for very low voltages and therefore surges caused by lightning can produce serious damages.

Residential and commercial structures require both protection against direct lightning strikes and from transient over voltages on power, communication and data lines.

Dhruva Technologies designs and installs all the necessary elements for the most efficient lightning protection for Residential and commercial high rises.

  1. Earthing and bonding system
    1. External earthing system
    2. equipotential bus bars
    3. equipotential isolation spark gap
  2. Lightning detector
  3. Overvoltage protection
    1. Over and under voltage cut off
    2. Type 1 protector at mains
    3. Type II protector at UPS
