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.

HV Cable Assets constitute in many EDB’s and private networks one of the largest asset groups by replacement value. In some of the larger EDB’s this may represent as much as $1.5 to $2 billion. Alarmingly, and at odds with almost all other asset classes managed by such networks, almost nothing is known about the asset condition of each individual cable. Effective HV cable asset management is seriously fraught by this situation. With the parallel scenario of above-ground infrastructure management challenges now painfully troubling the Industry, the risks posed by not knowing the condition of HV cable assets is now a very pressing problem, given the age profile of such assets and the uncertain dynamic of asset aging modelling.
Owning your own electrical contracting business is worlds away from being an employee: the hands on work may look the same, but behind the scenes… well, there's a good reason it's behind the scenes.
Almost everyone is an employee before they are a boss. People who become business owners often do so because they love their profession and want more control; the action of running a business is an unfortunate consequence.
If the world were honest, business owners would tell you that running a company is like being a firefighter: racing around putting out fires. There is no solution to that problem because it's not a problem, it's the job description.
How can you make your workday easier? Tighten up your business practices by staying organised and minimising distractions so you can put those fires out properly.
Take note of these tips, they will make your day as a contractor so much easier. You'll save money, stress less and find more time to enjoy your hobbies and family.
We all know the single most effective way to prevent power failures and shortened equipment lifespan is by keeping moisture to a minimum, along with heat and oxygen. It's fair to say that most equipment failure and subsequent losses (time, resources, etc) could be mitigated, through routine insulation testing.
When it comes to improving testing standards, the process is often long and expensive. Because of this, many industry players focus on improving test and measure equipment, which means we have very advanced tools that can often be let down by outdated regulations.
It also means when we do see updates to international standards, it's a very good thing and often welcome. One example is the adoption of DFR (Dielectric Frequency Testing) over traditional PF (Power Factor) and DF (Dissipation Factor), over 25 years after it was first introduced.
