Case Study: Impact of Thunderstorms

Photo credit:

The big, powerful storms that have rocked our nation in recent weeks have been damaging, dangerous, and scary. 

Although these storms have been unusually strong and intense, thunderstorms are very common events. They occur about 16 million times a year and about 1,800 are happening in the world right now. The lightning in these thunderstorms is five times hotter than the sun and one bolt has enough electrical energy to power 200,000 homes.

It is important for businesses and mission critical facilities such as hospitals, data centers, and utilities, to safeguard their equipment against the significant damage that can be caused by the high frequency transient energy of lightning strikes.

Protection starts with a power quality monitor, such as the PowerXplorer PX5. This enables you to assess any lightning-generated voltage transient and any impact on the equipment.

To see an evaluation of the most common PQ occurrence during lightning storms, Dranetz invites you to read our online case study:

Dranetz App Note: Corrugated and Cardboard Packaging

We’ll bet you don’t spend a lot of time thinking about corrugated and cardboard packaging, do you?

But take a close look and you’ll see that it’s all around us.  According to the New York Department of Environmental  Conservation (NYDEC), 90% of all products shipped in the United States are shipped in corrugated and cardboard boxes. That’s a lot of boxes, trees, pulp, power, and energy.  And that’s where Dranetz comes in.

Recently, Dranetz was asked by a large corrugated packaging manufacturer with multiple manufacturing sites on the East Coast and central parts of the United States to assist with assessment of planned expansions as well as ongoing energy management, and provide proactive power quality analysis. Using both the PowerVisa power quality demand & energy analyzer and a permanently installed Encore Series power monitoring system, the electrical design team was provided with crucial information on a host of issues, including energy usage and PQ problems originating all the way back to the electric utility itself.

The initial results were so successful, that over the next year an Encore system has been budgeted for every one of their plants. To find out more, click on the link below to download the complete Dranetz application note.
