Case Studies
Wavecrest is useful on a variety of different applications covering many power quality problems. The below case studies are intended to show a snap shot of the potential uses for the Wavecrest. If you have a power problem that you think Wavecrest can solve, feel free to reach out to us.
Flickering LEDs and Sag
Problem: After an LED retrofit in this medical office building, it was noticed that whenever the elevator ran or the AC came on, entire sections of lights were flickering. Turns out the building had some dirty power and the equipment startup was causing a voltage sag, which caused the LEDs to flicker.
​
Why wasn’t this noticeable with the old lights? Because the fluorescent gas inside the old tubes could maintain the electrical charge during the split-second sag in the power line. LEDs cannot. So it was on the installer to solve the problem.
​
Solution: 10 Wavecrest units across all of the lighting circuits in the building filtered the dirty power and solved the flickering issue while protecting the lights from further power quality problems.
Heat Pumps and Transients
Problem: The heat pumps were not working during outages despite the whole-house generator working properly. Something along the power line was causing the controls to not operate properly. Possibly harmonics or EMI noise.
Solution: The Wavecrest wired at the heat pump breaker, cleaned up the generated power and allowed the equipment to work as intended.

LED Lights and Overvoltage
Problem: The Tulsa Air and Space Museum had an overvoltage issue that was burning out their high bay lights. The LEDs were the unfortunate victims of dirty power. Contrary to popular belief, typical surge protection devices will NOT protect against this kind of power quality event. The fixtures were also hard to reach, so replacing them was a particular challenge.
Solution: 4 208v Wavecrest units installed at the lighting circuits are there to protect the LEDs from the overvoltage. Wavecrest has a patent pending relay disconnect that protects itself and all of the equipment on the branch circuit from the power quality event.
Gas Pumps and Dirty Power
Problem: A power quality issue, either harmonics, overvoltage, or spiking, was burning out the screens and credit card readers on gas pumps in Houston. This led to costly repairs - around $1,400 each pump.
Solution: 1 Wavecrest unit was installed at the branch circuit powering two pumps and successfully prevented the burnouts from continuing. Store owners benefit from less equipment repair cost and less downtime for each pump. Picture to the right is during installation. Installed picture coming soon.
