Surge Protection —
Protect What Lightning
Doesn't Destroy

Lightning doesn't have to strike your building to cause damage.
Surges travel through power lines and destroy sensitive systems in milliseconds.

We design surge protection as part of a complete, physics-based protection system.

Why Surge Protection Matters

Electrical systems today are more sensitive than ever.

A surge can be caused by:

Nearby lightning strikes
Power grid switching
Faults in electrical systems
Large equipment turning on/off

These surges can:

Damage electronics instantly
Reduce equipment lifespan
Cause data loss and downtime
Disrupt critical operations

Most damage happens without a direct lightning strike.

The Real Problem

Many buildings have:

Lightning protection systems
Earthing systems

But still experience equipment damage.

Why?

No surge protection devices (SPDs) installed
Incorrect SPD selection
Improper installation
Poor earthing connection
No coordination between protection layers

Without surge protection, your system is incomplete.

Our Approach

Layered Protection — Not Single Devices

At OHMdaddy, surge protection is designed as a coordinated system.

We implement:

Type 1 protection (main incoming supply)
Type 2 protection (distribution panels)
Type 3 protection (sensitive equipment level)

Each layer absorbs part of the surge energy. Protection works by reducing energy step-by-step — not in one point.

How We Design Surge Protection

System Assessment

We study your electrical layout and risk profile.

Surge Risk Analysis

We evaluate exposure from lightning and switching events.

SPD Selection

We select devices based on system voltage, surge current, and equipment sensitivity.

Coordination Design

We ensure proper energy sharing between SPDs.

Earthing Integration

We connect SPDs to low-resistance grounding.

Installation & Verification

We install and verify system performance.

Surge protection only works when properly coordinated.

What Is an SPD (Surge Protection Device)?

An SPD is designed to:

Detect voltage spikes
Divert excess energy safely to ground
Protect connected equipment

But here's the key:

An SPD is only as effective as the system it is connected to.

Without proper earthing and coordination, it cannot function correctly.

Common Mistakes in Surge Protection

Installing a single SPD and assuming full protection
Using devices without proper rating
Improper installation
Poor or high-resistance earthing connection
No coordination between protection stages
Ignoring protection for sensitive equipment

Many systems appear protected — but fail during real events.

Why Earthing and Lightning Protection Matter

Surge protection depends on:

Low-resistance earthing to dissipate energy
Proper lightning protection to reduce incoming surge energy

Without these, SPDs cannot perform effectively.

All three systems must work together.

Real-World Impact

Proper surge protection can:

Prevent costly equipment damage
Increase system reliability
Reduce downtime
Extend equipment life

This is not optional protection — it is essential.

System Integration Matters

Surge protection works together with:

Earthing systems
Lightning protection systems
Proper bonding and equipotential connections

Integrated protection is effective protection.

Where Surge Protection is Critical

Homes with sensitive electronics
Offices and commercial buildings
Industrial automation systems
Data centers and IT infrastructure
Solar power systems
Hospitals and critical facilities

If your systems rely on electronics — surge protection is necessary.

Our Guarantee

With OHMdaddy:

Your system is designed as a complete protection solution
Your SPDs are correctly selected and coordinated
