What is

cable testing?

Application and benefits.

• Necessary for laying new cables and commissioning

• Testing with a multiple of the nominal voltage

• Damage to the cable during laying and installation can

be detected

• Test result: “Pass” or “fail”

• VLF truesinus® testing ensures reliable information

What is

cable diagnostics?

Benefits.

• Non-destructive determination of the actual state of the

cable network

• Detecting defects in the insulation before they cause

disturbances

• Lower maintenance costs

• Reliable, non-destructive quality control after new

installations or repairs

• Increased power supply reliability

What is

tan delta loss factor measurement?

Application and benefits.

• Integral measuring method for reliable differentiation of
