Inspections for the Renewable Industry


Inspections for the Renewable Industry

If you need thermal imaging in the Renewables industry, look no further than the team at Geo Therm Ltd.


Based in the UK our team pride themselves on being the leading thermal imaging service company for the Renewable industry. We are EEEGR members, providing professional inspection services to support the renewable energy sectors, assisting clients to comply with periodic maintenance requirements, commissioning needs and or supply equipment whether it’s for onshore or offshore needs.


For more information simply contact our team of survey engineers and find out how our team can support you today with the latest handheld infrared (IRT) cameras and or fly-by and scan UAV infrared camera mounted drones for Solar Panel and Wind Turbine Inspections.

Solar Panel’s, Wind Turbine Inspections​ & Anaerobic Digestion Plant Inspections

One of advantages of thermal imaging is that there is no need to disconnect electrical or mechanical systems whilst performing live inspections, (that is after safety precautions have been implemented). With a trained eye, and thermal camera parameters set correctly extreme heat anomalies are discerned in real time to aid fault diagnoses. Solar cells, AD plant switchboard deficiencies, turbine blade composite disbonds or nacelle enclosed electro-mechanical equipment fault modes can all be recorded for trending purposes and corrective actions planned to ensure asset uptime.

Renewables - Inspections & Maintenance

Geo Therm Ltd are members of the East of England Energy Group (EEEGR) providing professional third-party inspection services & engineering O & M support to the renewable onshore and offshore sectors.

Utilising the services of a third-party provider like Geo Therm Ltd has long-term benefits.  Inspection routes become more efficient, equipment itinerary lists are regularly updated, and equipment is thoroughly inspected, furthermore our services are impartial, over the inexperience, bias, and time constraints of a workplace operative. While the duty manager knows the exact cost per visit so can forecast future maintenance finances and expenditure.

In short, the use of Geo Therm Ltd’s specialist renewable inspection services enable stakeholders that one stop-shop to a cost effective, professionally planned inspection that asset manager’s value, and auditors and insurance companies recognise.

For O & M requirements, our GWO certificated technicians can support client service teams carrying out engineering tasks in offshore and onshore wind turbine maintenance schedules. Ring-fencing our resource is a guaranteed way of ensuring you have the additional engineering support you need to deliver your contractual obligations to your client.

Equipped with thermal cameras, our drones can cover acres of land safely and rapidly, pinpointing deficiencies in individual solar panels from height, alternatively, we can undertake hand-held inspections for close-proximity work such as HV switchgear or transformers. Our on-site services also include; installation of IR inspection windows to switchgear and transformers, design, testing and commissioning services connecting the solar farm to the grid.

Using either a thermal infrared or Gas Find imaging camera our surveyors can locate high-temperature hot-spots in electrical systems and/or gas leaks in digestion tanks and process piping. Our inspection services provide the technology to identify incipient atmospheric leaks. Thermography can be used to save money, improve reliability and identify health and safety hazards.

Thermography using thermal imaging equipment operated by our qualified thermographic surveyors are regularly contracted to safely monitor the condition of all types of switchgear, motor’s, and distribution equipment. Assist with company PM schedules detecting problems such as: overheating in motor windings, loose electrical connections and ferrules, bus-bolt terminations, gearbox bearings and couplings.

Partial discharge (PD) occurs when arcing, tracking and corona activity is present in electrical HV assets. PD is caused by defects in the insulation, overheating and movement of motor stator bars, excessive operating electrical and thermal stresses. Our inspections measure the peak magnitude, providing long-term analysis of PD activity to enable trending and diagnoses on issues related to cyclic loading, humidity, and temperature.

Weathertight or watertight, the need for hatch, door and seal integrity is self-evident – to prevent ingress from wind, sand, and precipitation. Condensation, corrosion, and excessive wave action all have the potential to impact on turbine seal integrity. Our ultrasonic emission technology is a tried, tested and approved leak test methodology. A recognised technology applicable for hatch, window and door seal integrity on all types of marine vessels.

Infrared (IR) windows provide a safe means to visually inspect and detect failing electrical equipment while still under load. Providing a line of site into the asset for inspections aiding operational reliability without the need for drawn out processes and paperwork (i.e. permit to work), bulky PPE or shutting the system down because of risk of electrocution or arc flash. Additional EMSD’s we supply and install include the Delta T Alert® temperature probe, once configured this small device will continuously monitor the internal asset temperature against the external ambient temperature, any deviation against set parameters will trigger an email alert, directing the engineers to the exact location of the asset requiring attention. We also provide equipment Data Tags, these near field communication (NFC) devices are ideal for retaining current asset maintenance information, or using the more versatile cloud based E-Sentry tag system – a real-time asset maintenance information portal that also holds historical data on the same asset and can be accessed remotely anywhere in the world.
