Our different interventions:
Maintenance : visit or contract
These are interventions to minimize the risks and costs that can come from any equipment failures.
Our different types of interventions provide solutions that range from simple control visit to complete solutions including interventions, replacement parts and periodic visits ... adapted to each client. The maintenance contract gives you the certainty of being repaired first.
Process of an intervention :
- Visual verification of the device status.
- Verification of mechanical elements, tightening of the connections, ...
- Control of electrical parameters.
- Performance test.
- Cleaning and dust removal of the equipment.
- Providing a complete service report with recommendation.
Our technicians provide industrial troubleshooting on all products and all brands associated with electrical backup and power saving such as inverters, battery chargers, power sets, low voltage capacitors ...
- Phone support 24/7 proposed in option to our customers to have an additional phone number to contact a technician AUNILEC outside regular working hours: 24 hours a day, at any time of the day, on Sundays and on bank holidays,
- Quick intervention is guarranteed
- Emergency spare part available in stock
- Ready to rent equipment in case of failure on site.
Our technicians ensure the commissioning of the equipment on site along with personnal training to transmit the knowledge necessary for optimal operation. We can also step in to ensure disconnecting or moving devices.
Progress of an intervention :
- Checking of the device connections
- Commissioning and Verification
- Tests and adjustments
- Training with recommendations for the use of the inverter
- Providing a commissioning report
- Providing a complete service report with recommendations
The reliability of the repairs is our priority, we systematically apply the following process :
- Diagnosis and search for the origin of the fault
- Replacement of defective components (batteries, fans, electronic cards, ...) after acceptance of our repair estimate
- Cleaning the unit
- Restarting and tests
The inverters with a power of less than 6 kVA are systematically sent to workshop repairs in order to reduce the costs of intervention.
- Infrared thermography
- testing of electrical networks
- Power results
OUR GOAL: ENSURE CONTINUITY OPERATION OF YOUR INSTALLATIONS
The intervention consists of an analysis and a complete diagnostic of electrical networks: harmonic measurements and cosine Phi.
General information on harmonics:
Non-linear loads absorb a current with distortion due to the presence of components in multiple frequency of the fundamental frequency. The non-linear loads can be compared to an overcurrent which is removed from the system at the fundamental frequency and fed back into the network at higher frequencies. The waveform of the intensity, even with distortion, also results from one period to another. This means that all frequencies in the waveform are harmonics of the fundamental, and multiple of whole numbers.
The harmonics present in industries are generated by devices known as power grids polluters:
- inverters, rectifiers, variable speed drives
- motors, transformers
- Fluorescent lamps, arc welding machines
- Chargers, switching power supplies ...
The presence of intensity and harmonic voltage can reduce the effectiveness of equipment operation and generates the problems described below:
- Deterioration of power factor correction capacitors
- Damage to equipment
- Overheating of the transformers
- neutral conductor overload
Interest of harmonic measurement:
Your electricity consumption has perhaps a significant portion of reactive energy billed by EDF.
We have the possibility of:
- substantially decrease this expense by installing compensating devices (capacitor banks)
- Significantly reduce the presence of non-sinusoidal currents in power grids by adding three-phase filters to reduce harmonics.
The capacitors guarantee a rational use of energy, by reducing the effects of current costs and at the same time the losses by Joule effect of different power transmission components (cables, fuses, switches, transformers).
That's why we offer you a complete study of your installation and perform measurements on site to check by technical, reliable and accurate means, cosine and harmonic rates before installing an adequate compensation material which will allow you to save money. This check is conducted without perturbation of the existing material operation.
Infrared Thermography is mainly an imaging and measurement technique for a rapid and repetitive diagnosis. It detects failures and track the possible changes to underlying phenomena bringing a deterioration of the organ.
Object of an intervention
Infrared thermography is a preventive maintenance inspection to detect and anticipate the abnormal overheating. It allows for a correction on the installation and it ensures better operation:
- Identify, in electricity infrastructure support, overheating that can have various origins: bad connections, overloads, phase unbalance, faulty contacts ...
- Anticipate and avoid: expensive equipment degradation, production stops, operating losses, fires ...
- Provide decision elements for performing corrective interventions, and to anticipate on possible work to be done, since they have been identified.
- Facilitate the maintenance of electrical installations (time saving and safety)
Downstream overheating of the circuit breaker, at phase 3
Intervention time limit
Priority 2 (Urgent Action)
Thermography Infrared targets electrical cabinets, transformer stations, power rails, ... The objective is to highlight terminal tightening defects, contact wear, calibration sub-conductors, phase unbalance, clamping the insulation, deteriorated insulation.
Interest of thermography
It improves preventive maintenance actions from the establishment of a technical history, operation and maintenance costs. It must make the decision elements for a repair that may be planned. The aim is to detect as early as possible the organ failure before an actual degradation leads to lengthy and costly remedies. Moreover, the procedure is performed by a qualified and authorized technician to move safely on site and powered environment. Our rates include the action plan and the submission of a report accompanied by digital and thermal images with diagnoses and degrees of urgency for rehabilitation equipment.
