VZ220 OL

Online VZ220

The Conductivity Meter For Transformer Oils VZ220 OL is designed for measuring of the relative permittivity, the volume conductivity and the dissipation factor during the oil purification process. It is normally installed in combination with the VZ212A (water and gas content measuring) on a VOP (Variable Oil Purification) unit. The instrument VZ220-OL is developed identially like the standard VZ220 according to the new IEC 61620 standard by using the alternate square wave method. This method permits an accurate determination of above quantities at process temperatures of the VOP unit. All signals and measuring values are stored on a digital printer for reporting the performance of the oil purification process.
