In electrical substations of higher voltage levels, capacitor voltage transformers, also called CVTs, or CCVTs, can be found.

VOTANO 100 now uses a new method that can determine the capacitances C1 and C2 on all CVT designs, combining two variable-frequency measurements at low voltage. It injects a constant current into the secondary winding and measures current and voltage accordingly. The first measurement determines the frequency dependent short-circuit impedance including C2.

The second measurement determines the frequency dependent short-circuit impedance including C1 and C2.

From both measurements, C1, C2, the capacitive ratio Kc, and the total capacitance Cr can be calculated. This method for measuring the CVT capacitance is integrated as a new test in VOTANO 100. VOTANO 100 can measure both the capacitance and the accuracy of the CVT, which is ideal for diagnostic purposes.

Los transformadores de tensión se utilizan constantemente por toda la red eléctrica y su vida útil puede llegar a los 40 años. En ese tiempo, los efectos del envejecimiento, el funcionamiento regular, fallas de red o las influencias externas pueden afectar a la integridad del transformador. Las empresas realizan varias pruebas durante la puesta en marcha y el mantenimiento para detectar irregularidades provocadas por el transporte, la instalación o el funcionamiento diario.

Voltage transformers are used around the clock throughout the energy grid, and their life span can reach up to 40 years. During that time, the effects of aging, regular operation, network faults, or external influences may affect the integrity of a voltage transformer. Utilities perform various tests during commissioning and maintenance to find any irregularities that have been caused by transportation, installation or daily operation.

Potential transformers, or voltage transformers, must accurately reflect system conditions for revenue metering, protection, load control or similar applications. Calibrating a voltage transformer means determining its accuracy and respective error according to the applicable standard. Accuracy classes are defined by international standardization bodies such as the IEEE and the IEC. OMICRON’s VOTANO 100 uses a modelling approach for verifying the accuracy of inductive and capacitive voltage transformers.
