Compatibility Part 5: Who shares the responsibility for compatibility and reliability testing? (MAGAZINE)

Part 5 of PHILIP KEEBLER’s series on compatibility explains that LED lighting manufacturers share responsibility for implementing robust products that can withstand disturbances and work in a compatible manner with the nuances of the power grid.

Responsibility for compatibility and reliability testing shares a three-legged stool. Utilities, end users, and manufacturers share the responsibility. Fig. 1 shows the relationship between the location of the disturbance, the number of disturbances and people affected and their respective area of responsibility.

Utilities were the first to realize that they are responsible for the disturbances that occur on their power systems – transmission and distribution. Many events affect the operation of the power system – vehicle accidents, contractors digging holes, and thunderstorms to name a few. Even though the utility did nothing to cause these events, their customers still end up experiencing some type of voltage problem that might only have caused their lights to blink or might have caused an over-voltage condition that burned up many electronic ballasts or other electronic loads.
