Harmonics and Voltage Surge Monitoring Solutions

Protect your transformers from premature aging and stabilize the grid

Power inverters in wind and solar farms generate harmonics and switching surges that can age transformers prematurely. These harmonics can also damage surge arrestors and bushings creating unnecessary maintenance costs along with grid instability. 
A wind power or solar plant must ensure that the quality of power being delivered to the grid is excellent. At the same time, the generator should be able to handle disturbances coming from the grid. Harmonics are one of the more common power quality issues presented by large renewables plants because of the high switching frequency of the power inverters.
Qualitrol has developed a low cost 3 channel device to monitor these parameters for wind and solar farms on the collector circuits to give an overview of the health of your assets.

Did you know that Hydrogen is a key indicator of transformer problems and an on-line indicator can flag those pending problems in-between annual checks? In fact, oil sampling will only be necessary after a positive result from the Hydrogen Indicator.
