Resistors for Renewable technologies

Cressall has developed the resistors suitable for your green power generation project.

The increasing importance of sustainable, low carbon power generation means that electrical engineers have to be able to confidently specify components and equipment that have been developed for use in such applications. Cressall has made significant investment in the design and manufacture of resistors for the testing, generation and control of renewable energy. Our engineers have more experience than most in providing practical solutions for the power generation industries and this shows in our innovative and comprehensive resistor ranges.

Using the sun’s rays to generate electricity or to heat water is a well proven technology and even here resistors can help to improve the efficiency of the collector systems.

Solar panels which can track the sun to ensure optimum efficiency will often use electric drives in their positioning system, like the electric drives in hybrid vehicles these can use Cressall braking resistors to ensure that the panels stop when required, and as these resistors are passive devices and have no wearing components they will last as long as the panels themselves.

Load banks can be used to test solar installations as an island, separate from the grid connection. This provides the benefit of being able to test the complete installation using a controlled load, not just the solar panels themselves. Being able to check the proper operation of a new install irrespective of grid connection availability can be the difference that keeps a project on schedule.

Biomass can include wide variety materials such as wood, energy crops, agricultural residues, food and industrial waste, biomass is converted into energy through combustion, this process like fossil fuels releases CO2 into the atmosphere, however, it has several advantages over its ‘stable mate’.

Production of the wood and agricultural residues for biomass will consume CO2 as part of the process and so in part will off set its production later in the process.

The use of food and industrial waste will cut down on landfill and improve levels of recycling.

Harnessing the wind is one of the cleanest, most sustainable ways to generate electricity. Wind power produces no toxic emissions and none of the emissions that contribute to global warming. This, and the fact that wind power is one of the most abundant and increasingly cost effective energy resources makes it a viable alternative to burning fossil fuels.

Cressall Resistors designs and manufactures a range of components that form essential parts of any wind-farm installation:

Pre-Insertion Resistors
Crowbar Resistors
Neutral Earthing Resistors
Dynamic Braking Resistors

Resistors for Static VAR Compensators

Although tidal power generation is not as common as wind or solar generation its predictability gives significant advantages when compared to generation by wind or sun. The relatively high set up costs combined with the restricted locations into which the equipment can be installed is gradually being offset by improving turbine technology.

A tidal stream generator operates in much the same way a wind turbine does and so has similar requirements for the resistors manufactured by Cressall:
