Partial Discharge / Tan Delta

VLF / Tan Delta / Partial Discharge

Facility owners and managers frequently focus maintenance attention and budget on their electrical equipment while overlooking the cables that interconnect this equipment. Periodic assessment of these major and expensive cable assets should be included as part of any maintenance program.
DC High Potential Testing was for many years the choice in cable testing. However, with improved technologies there are alternatives to this form of testing. Contact Sigma Six for information on current standards that you should be aware of prior to testing your cables. 
Sigma Six has trained personnel and owns instrumentation based on current technology to perform Very Low Frequency (VLF) withstand testing, loss angle/dissipation factor (Tan Delta) and partial discharge (PD) diagnostic testing.
