High-voltage transformer repair

In general, high-voltage transformer repair is carried out in two phases. There is a phase of preventive repair and a phase of corrective repair. In both cases, the intention is, of course, to restore your system to a good condition and ensure its proper functioning.

We proceed as follows:

  1. Diagnostic of the high-voltage transformer
  2. Analysis and detailing of existing defects
  3. Formalization of the analysis
  4. Expertise of our technicians to resolve malfunctions

Defects on a high-voltage transformer

What are the different types of defects that can be found in a high-voltage transformer?

– Hotspot on a load tap changer
– Electromagnetic type defect: internal or external short circuit, displacement of windings
– Dielectric type defect: overvoltages in the network, lightning strikes, winding insulation breakdown, excessively acidic oil
– Oil leak: at the bottom of the tank, at the base of terminals, or along the tank

High-Voltage Transformer Maintenance and Repair Service

In order to carry out regular maintenance of your high-voltage transformer, we offer maintenance and repair services for them. Here’s how we proceed:

– Analysis of oil and dissolved gases
– Identification of thermal and/or electrical defects in the transformer
– Inspection of the electrical insulation role
– Analysis of furanic derivatives content and PCB content
– Verification of transformer compliance with standards
– Inspection of equipment, tightening of connections, grounding, and locking mechanisms
– Cleaning and general dust removal
– Infrared thermography
– Replacement of gaskets and bushings, plug-in terminals
– Verification of transformer protections
– Insulation inspection

    Refurbishment

    We test the resilience of the transformers. Mechanical tests assess the behavior of equipment under real usage conditions by applying mechanical stresses to it. The transformers are fully disassembled and cleaned. Aging components (gaskets, screws, primary and secondary terminals, protection relays, and accessories) are replaced. Each device repaired in our workshops is accompanied by a test report that conforms to the specifications of new devices.

    The 10 Phases of Factory Refurbishment for a TGBT France Transformer:

    1. ARRIVAL OF THE TRANSFORMER AT THE FACTORY
    2. DIELECTRIC ANALYSIS OF THE TRANSFORMER
    3. TESTING OF WINDINGS AND ELECTRICAL COMPONENTS
    4. DRAINING AND DE-TANKING OF THE TRANSFORMER
    5. REWINDING IF DEFECTIVE WINDINGS
    6. DRYING AND CLEANING OF THE TANK AND ACTIVE PART
    7. PAINTING OF THE TANK AND INTERIOR/EXTERIOR
    8. VACUUM FILLING
    9. ELECTRICAL TESTING ON TESTING BENCH
    10. CUSTOMER DELIVERY
