Agente para distribuir-Analizador de respuesta de frecuencia de barrido FREX

Los transformadores de potencia son uno de los componentes más importantes en la infraestructura de transmisión y distribución actual. Los cortes de energía y las reparaciones no planificadas causados por fallos en transformadores pueden convertirse en gastos significativos. Por lo tanto, it is particularly important to avoid transformer faults and conduct reliable and efficient testing and diagnosis.
The FRAX series sweep frequency response analyzer (SFRA) can detect mechanical and electrical changes in iron cores and windings. The FRA method has been used by major power companies and contractors for over 10 years. The measurement process is very simple. By obtaining a unique “fingerprint” of the transformer and comparing it with the reference “fingerprint”, the conclusion of whether the mechanical components of the transformer have changed can be directly obtained.
The deviation of the fingerprint indicates that the mechanical or electrical structure inside the transformer has changed.
The issues that FRAX can detect include: winding deformation and displacement
Interturn short circuit and winding open circuit
