VLF Testing

VLF cable testing (Very Low Frequency) is a technique for testing of medium and high voltage (MV and HV) cables. VLF systems are advantageous in that they can be manufactured to be small and lightweight; making them useful, especially for field testing where transport and space can be an issue. Tan Delta, which is increasingly common in today’s test procedures. Also known as Power Factor and Dissipation Factor testing, these state of the art instruments give the user a wide range of results for qualitative cable assessments such as degradation and lifetime estimations on MV and HV systems.
