From the detailed design to the final realization
Basic requirement of the customers of manufacturers is to be ensured by proved and precisely documented methods that the products under procurement are satisfying the requirements of the planning parameters and industrial standards. That is why the test laboratory is one of the most important parts of a factory. From this reason the basic interest of the manufacturers is to be able to produce the necessary measurements with high reliability and effectiveness in safe and automated measuring environment to increase the productivity and to promote the quality management. Diagnostics Ltd already has high competence in construction of complete test laboratories including the conceptual and detailed design, the whole controlling, data evaluating and management system to achieve the aims above.

- Insulation resistance tests
- Routine Test Area
- Applied HV withstand tests
- Induced HV withstand tests
- Load loss and short circuit impedance measurements
- No-load loss measurements
- Zero order impedance tests
- Heat Run Test Area
- No-load loss, load loss and winding resistance measurement
- PD and Noise Test Area
- Specially designed cabin with noise suppression wall cover for noise level measurements and with electrical shielding in order to remain under the 2pC PD noise level for measuring cast resin transformers
- The noise and PD cabin can be separated in different rooms according the user’s needs
