2) Utility Grid Switching

Utility grid switching is a major power quality issue that can cause powerful external transients.

Power generating utilities break the distribution of power into grids.

The electric companies distribute power to each grid in a steady stream at all possible times, regardless of fluctuations in demand.

Unfortunately, this can cause problems for customers.

Each customer's power needs are constantly changing, thus constantly changing the overall grid needs.

Instead of adjusting the power generating equipment output for each changing power demand situation, the electric companies adjust by switching the supply of power from one grid to another grid.

When the grid supply is switched, very large surges are created. These transients can reach as high as 25,000 Volts!

3) Power System Faults

Power System Faults are essentially a sudden disruption in a normal electrical system or grid caused by a short or open circuit.

Shorts or open circuits can occur in power distribution equipment like transformers, transmission lines and generators. These faults can be very destructive.

Typical causes of power system faults:

• Lightning

• Falling Debris Across Power Lines

• Vehicles/objects Striking Power Poles

• Wind and Ice

• Natural Disasters

• Overvoltages

• Mechanical Damage

• Fire

• Suicidal Squirrels

• Human Error

The resulting voltage surges from system faults can be in the tens of thousands of volts and amperes.

Conclusion

If your business or home is on the receiving end of one of these external surge events…it's going to be a very long and expensive day...especially when the damage could have been prevented or at the very least mitigated.

Don't take chances with external transients. Take preventative measures.

Remember...It only takes one hit.

Protect your systems with high quality high performance equipment.
