Mr. Neier (a graduate Ing. & MBA) is an expert in MV cable diagnostics with numerous years of international experience. He has worked as a Technical Advisor for power utilities across the globe to establish diagnostic philosophies that go beyond simple application of diagnostic devices. His extensive background as Trainer and Consultant has also allowed him to publish papers and presentations in this field at events such as CMD, IEEE PES, Cable Tech, EDC SEA, GTD Asia as well as CIRED T&D conferences.
Cable diagnostics based on very low frequency tan delta and partial discharge measurements requires defining clear application procedures covering new installations, maintenance testing after repairs as well as regular inspection. Residual lifetime estimation, which is based on the latest software, then allows investment planning by asset managers. This presentation explains how quality of newly laid cables, including newly installed accessories such as joints and terminations, can be verified using a ramp up diagnostic sequence followed by a monitored withstand test covering measurement of TD loss factor and PD.
