Sound commercial and operational responses now to hand from a timely innovation
With increasing regulatory scrutiny, New Zealand distribution lines businesses are now facing a time of budgetry austerity and increasing pressure to improve asset management knowledge and practice.
A newly-released but long-standing technology called Distribution Fault Anticipation (‘DFA’) is being offered to the Industry under a unique companion implementation and consulting package.
Unlike any other technology in concept or contribution, the DFA implementation model offers innovations that address a great many of the commercial challenges facing the distribution lines industry. The technology provide an effective means to identify developing faults and manage asset degradation throughout the asset lifecycle, thus providing lines companies and Asset Managers a clear step change to a new phase in the evolution of Asset Management practice globally.
New to New Zealand, the adoption of DFA presents an opportunity to progress from the reactive corrective maintenance practices that have been traditionally employed to enable preventative maintenance on MV lines to avoid unplanned outages. Providing the unique ability to anticipate many faults before they have an impact on customers and feeder reliability, DFA/HiZ offers the following advantages and benefits:
- Improved safety for staff and the public.
- Improved efficiency (reduced cost) of field line repairs (reduced OPEX).
- Faster response to line faults by field crew (increased network availability).
- Network risk reduction – especially bushfire and electrocution risk.
- Increased asset life and improved asset management decision-making (more targeted and effective Capex investment).
- Improved quality of supply.
- Improved customer satisfaction.
- Improved senior management regulatory reporting ability.
- Demonstrable evidence of appropriate, measured and targeted investment based on pin-point determination of asset fitness within the asset lifecycle curve.
Implementation of DFA/HiZ provides a range of other accessible logged data and information plus many of the features of a digital fault recorder providing additional functionality and capability to analyse customer complaints and distribution feeder performance
