Wind Energy

Minimize downtime and control operating costs.

Wind generator technology continues to evolve with increased efficiency, improved reliability, and extended life spans.  With over 60,000 turbines in the U.S. and record growth projected in 2021, O&Ms are faced with a monumental and uncertain path to achieving an optimum balance between minimizing downtime and controlling operating costs.

High voltage tests such as surge tests and partial discharge (PD) tests are essential for O&M operators who want to predict what failures can be expected and when using a data-centric approach.  Program the iTIG to perform the same test, the same way, every time.  Tests conducted over a period of time give users trending data so O&Ms can prioritize turbine servicing and schedule maintenance rather than risk unplanned downtime.

With over 20 low-voltage and high-voltage tests and measurements, the iTIG gives a complete picture of stator and rotor insulation condition.  Also test rotor lead connections and surge arresters.  Knowing the electrical health of generators gives wind site managers the data they need to prevent unplanned downtime and control operating costs.

Electrom is a proud member of the American Clean Power (ACP) trade association.  Together, we are making renewable energy, in particular wind energy, a reality for today’s economy and for generations to come.  With a legacy fleet of wind turbine generators and record growth expected in the coming years, there has never been a better time to play a role in making clean energy the dominant electricity source in the United States and beyond.

Up-Tower Testing

Working in small spaces always presents challenges for technicians in a nacelle.  Up-tower testing is achieved with the iTIG’s rugged and lightweight design. Technicians can easily hoist the instrument and the compact construction allows it to be propped up in a work space or set on end if space is tight.

Up-Tower Reliability

Generator reliability and maintenance is a concern for all wind site operators and maintenance professionals.  Electrom’s iTIG gives O&M managers the electrical tests they need to verify generator health and insulation condition. Low voltage electrical tests are used to ensure that the generator can be safely energized and failure is not imminent. Higher voltage tests can be used as a predictive tool to indicate the longevity of a generator’s windings.

Use the iTIG winding analyzer to perform the following low voltage and high voltage tests that are recommended by the American Wind Energy Association (AWEA):
