Lightning Surges are  the single biggest cause of damage to and destruction

of electrical and electronic equipment in homes?

Due to the ever-changing climate and rising temperatures lightning strikes are

becoming more and more frequent.

Several things can happen in a storm. Some more catastrophic than others. The other issues are directly related

to lightning activity. When lightning strikes nearby (but not too close hopefully!), electrical spikes & surges are

generated, and these can transmit into electrical wiring. We are referring to lightning surges here.

The 5 levels of protection we would recommend for any situation are:

POWER CUTS

During storms, network disruption can frequently happen

and power cuts are extremely common. There is not much

you can do but you can use products to provide power like an

Uninterruptible Power Supply (UPS).

POWER BACK SURGES

These happen hand in hand with power cuts. When power

resumes, it is usually accompanied by a surge. This can be

quite high and result in severe damage. So, delay on start-up &

monitoring until supply is safe is critical. Use the AVS range to

protect against this event. A UPS will help as well.

HIGH VOLTAGE

(also known as voltage swell or surge) – That is a sustained

high level of voltage to typically >250V and up to 300+. These

could be catastrophic if the voltage rises very high, very

quickly. Here we would recommend using our AVS range of

products which will disconnect the power until it returns back

to normal.

LOW VOLTAGE

Generally happens when the grid is overloaded and you get

excessive voltage drop on the distribution network. You can

again use our AVS range or typically add a voltage regulator

LOSS OF NEUTRAL

Due to an accident or sabotage – In this event, the single phase

voltage will then rise to the 3 Phase level. So instead of getting

230V, the equipment will experience up to 415V continuously.

An extremely serious event. And not that uncommon. The

AVS range would protect against this. But even so, the AVS

might get damaged but at least it will do so with circuit open

appliances protected.

LIGHTNING SURGES

These are high energy surges generated by nearby lightning

activity that will raise the (voltage) potential in the

surrounding areas to thousands of volts and could seep into

buildings and thereby subjecting equipment to harmful surges.

Acumen Technologies supplies a number of products to cater for the above events to protect your equipment
