Data Line CDN

Data Line CDNs

Conducted Immunity Testing
Power line CDNs are typically characterized by the Equipment Under Test (EUT) parameters of voltage and current. The power line frequency is fixed so all other parameters are known. Testing on data and signal lines introduces another factor that must be considered, the data transmission type and speed.

Power Line CDNs

Conducted Immunity Testing
Is my CDN compliant to the latest IEC 61000-4-5 requirement? The latest amendment of IEC 61000-4-5 (2017) raises issues related to the use of surge CDNs for high current and DC applications. In fact there are two separate issues that need to be considered.

VLF Diagnostic Cable Testing

Cable Testing and Diagnostics, Partial Discharge Testing

Very low frequency (VLF) diagnostic testing is the application of an AC sinusoidal waveform, generally applied at 0.1 Hz or lower, to assess the quality of electrical insulation in high capacitive loads, such as cables.

Cable Fault Location Measuring Methods

Cable Fault Location

Faults in cables can arise due to any defect, inconsistency, weakness, or non-homogeneity that affects the performance of the cable. Typically, faults are classified as:

The Basics of Partial Discharge Testing

Partial Discharge Testing, Cable Testing and Diagnostics

Partial discharges (PD) are evidence of a degrading insulation system, which could lead to very costly repairs and can predictively lead to an electrical breakdown of high voltage apparatus.
