The quality at TCT


Product quality and customer satisfaction are our first priority

From design to delivery of our products, everything is implemented to ensure the control of our processes. 


An innovative and robust design based on :

  • A wealth of experience in the magnetic solution design
  • Structured project management from design to production
  • Rigorously selected and qualified business partners
  • An active technological benchmark


A strict quality control at each step of the manufacturing : 

  • Check of incoming supplies
  • Check of the magnetic properties after heat treatment
  • Unitary final check of the main characteristics


 A laboratory with suitable equipment :

  • Automatic test bench for partial discharges (programmable voltage curves up to 20kv)
  • Dielectric test bench (up to 20kV)
  • Measuring equipment for insulation resistance (up to 1kV)
  • Test bench for measuring permeability and losses on magnetic circuits (frequencies between 20 Hz and 200 kHz)
  • Automatic test bench for electrical characterization (transformation ratio, winding resistance, leakage inductance, parasitic capacitance, impedance, ...)
  • Automatic test bench for current transformer (conformity to standards, phase and amplitude error)
  • Pulse transformer test bench (rising time and U*t measurement)
