We read with much interest “T&D Testing Topics” about the role and importance of lab and field testing to the electrical power industry. When Chuck published this recently as part of reviewing 2015 activities he described many different test activities by various organizations with very diverse purposes. From there now we want to look ahead to the testing areas in which we expect significant change and rapid development in 2016.
Utilities need remaining life assessment methods and better targeted maintenance programs based on testing experience. Considering integration of renewables, local testing of an integrated system has to be addressed. Another challenge is how to transform Big Data provided by new Smart Grid applications to good use and better Asset Management.
Manufacturer’s intentions with testing
First, let’s clarify that the “testing” examined in this context is budgeted testing on equipment for Transmission and Distribution (T&D) grids, rather than the routine tests that are part of a regular manufacturing process. There are many reasons to undertake and invest into these programs: safety, reliability, liability, performance, compliance to standards and regulations, life expectancy of assets, functionality and more.
Traditionally manufacturers of switchgear, transformers, cables etc. need certification. Type-test certificates show compliance with IEEE ANSI or other internationally recognized standards. This is desirable for market introductions and subsequently may be required for larger international tendered projects. Certificates can cover risk and liability, although that’s considered more outside than inside the US.
Vendors can have many intentions with testing. First there is the verification of new designs and functioning of prototypes at the end stage of product development. When there is a significant change in standards, type tests must be renewed, as was the case recently when requirements for Internal Arc resistance became stricter. Safety testing is fundamental and, together with its traditional UL listing, has become essential for commerce: the demand chain ceases to function without it.
Modern development of newer technologies faces banks or other investors who want independent evaluation and proof of reliable and expected performance for instance of solar PV modules or BESS. It is remarkable that sometimes a manufacturer pushes more severe requirements for a test program than the standard demands, but it happens. We saw that for instance a few years ago with such a seemingly end-of-development product as glass chain insulators: in this instance a manufacturer created a competitive edge by distinguishing itself from the competition.
