Tecnalia

We carry out full electrical type tests on low voltage electrical panels, distribution panels and capacitor banks to correct the power factor in accordance with the IEC 61439 Standard on Low Voltage Switchgear and the IEC 61921 Standard on Power Capacitors.

We offer the following services:

TESTS

Resistance of the materials and parts
- Corrosion resistance
- Properties of the insulating materials
- Verification of the thermal stability of enclosures
- Verification of the resistance of insulating materials to abnormal heat and fire due to internal electric effects
- Lifting
- Mechanical impact
- Marking
- Degree of protection (IPXX)
- Insulation distances and creepage distances
- Protection against electric shock and integrity of protective circuits
- Effectiveness of protective circuits
- Earth continuity between the exposed conductive parts of the set and the protective circuit
- Short-circuit withstand strength of the protective circuit

Dielectric properties
