A Short, but Representative, ‘Perspective Piece’ on Industry Uptake of ‘Near 50 Hz’ PD Testing Internationally

Trevor Lord Director, AVO New Zealand and LORD Consulting.

When assessing what might at first appear to be a “new technology” in the power industry, it is reasonable of any client to seek a degree of evidence of its established provenance offshore and in the application to which it is intended to be applied in the ‘local’ context.

When assessing what might at first appear to be a “new technology” in the power industry, it is reasonable of any client to seek a degree of evidence of its established provenance offshore and in the application to which it is intended to be applied in the ‘local’ context.
When that ‘new technology’ is in fact well established offshore but new to the local market, one must consider the question as to what would constitute a suitable level of information to inform, address, and allay in reasonable fashion any uncertainties or questions as to the suitability of the technology for the intended application and also the quality of its said provenance. Clearly, no technology will ever hold 100% of the market or technical opinion but it would be a fair observation that evidence of widespread uptake over a longer term, coupled with a selection of technical papers that all concur on the technical quality and advantages of the technology over alternative or conventionally deployed solutions, should be deemed to be a tipping point to allow that technology’s confident
and optimistic deployment locally. The purpose of this letter to convey to you and your colleagues the background, deployment level, international uptake, and technical evidence enough to allow your company to embrace with confidence the ‘near 50Hz’ partial discharge cable diagnostic testing technology applied to both new and in-service condition assessment of your 11-33 kV cable population.
