Wind Turbines and TV Interference

Wind Turbines and TV Interference
April 12, 2013 admin

Assess the Television (TV) interference risk of a site. Gain a full understanding of the TV interference levels that can arise for your wind project.

There have been many occasions where wind turbines have been a source of disturbance in the transmission of TV signals, followed by complaints from local communities. At Pager Power, we have the experience and offer a range of services to identify, and recommend solutions to, potential TV interference issues.

TV Reception Surveying

We have conducted a large number of TV surveys in England, Scotland, Wales, Northern Ireland and the Republic of Ireland. For UK wind developments, planning authorities usually require a legally binding commitment. There a numerous turbine TV planning conditions including Section 106 of the Town and Country Planning Act 1990 and Section 75 of the Town and Country Planning Act 1997. Both require a TV reception survey prior to the erection of wind turbines –  this is what we call a Baseline Survey.

We have our surveying vehicle, with a 10m aerial.

Baseline

The most robust way of investigating whether interference will occur is to perform baseline television survey in potentially affected locations or places that complaints have already been made about the current television reception (analogue and digital).

This type of survey measures the television signal strength, carrier to noise and video to audio levels,  signal strength and bit error rate followed by a subjective assessment of picture and sound quality coupled with an assessment for the interference, if any occurs.

The measurements are undertaken using advanced television analyser for both analogue and digital signals.

A wideband TV aerial is used at 10m above ground level.

Post-Construction

Conducted once the turbines are up and turning, the purpose of a Post-Construction TV Reception Survey is to quantify the signal strength in locations where interference is deemed likely.

Ordering Your Survey

Our consultancy services are tailored to your site. This means that it is hard for us to assign a fixed price for these services.

To order a survey please complete the following:

1.Call us (+44 (0) 1787 319001) to discuss your site. Alternatively send an email to info@pagerpower.co.uk

2. Wait for us to send you a proposal with bespoke costing

3. Respond with written confirmation of your order

You can expect your survey to be undertaken within a maximum turn around time of 6 weeks from order. However this may vary due to factors that cannot be accounted for, such as the weather.

Quick and simple – Online TV Interference Chart

Another way that we can help you to assess wind turbine TV interference is by using our online report called a TV Interference Chart. This is a great way for you to get an initial overview of potential TV reception disruption issues with your site (up to 20 x 20km).

The chart will identify areas where a Television Reception Survey (Baseline Survey or Post- Construction Survey) is required.

Need a little help?

    Dear Julia,

    Thank you for getting in touch, and sorry to hear you’re having trouble with your television reception.

    There are lots of things that can cause disruption to television signal, wind turbine interference is one of them, but to determine the cause would require a detailed assessment. This may be something that the developer is prepared do – it may even be an obligation depending on what conditions were set when planning permission was received.

    If you are concerned that it may be the turbines that are causing the problem, I suggest that you contact either your local planning authority or the wind farm developer directly to register the issue.

    Best of luck!
