EMIN at VIIF 2018

Discover the seminar series on electromechanical maintenance and solar infrastructure hosted by EMIN and Fluke in Da Nang and Southern Vietnam. An opportunity to experience equipment firsthand and standardize high-voltage safety practices!

When a factory equipped with a rooftop solar array experiences a sudden drop in power output, it often sparks a dispute between the facility's electrical team and the solar installation contractor, with each side prone to blaming the other. The quickest way to resolve such a conflict is to accurately interpret the signs on-site—avoiding guesswork and refraining from hastily blaming the solar panels.

A solar panel reports a drop in output, yet the entire array continues to operate normally where does the fault lie? The answer often becomes apparent the moment a field engineer measures two fundamental parameters: open-circuit voltage (Voc) and short-circuit current (Isc). These two figures make it possible to isolate faults whether in the panel itself, the wiring, or the charge controller without needing to disconnect the entire string from the system. This article details the standard engineering measurement procedure and explains how to interpret the results, eliminating guesswork when troubleshooting panel issues.

In many automated workshops, control systems occasionally experience issues where output signals freeze or become unstable, or fail to accurately detect minuscule components passing through narrow gaps on the conveyor belt, causing the machining process to halt abruptly without an apparent root cause.

A transformer test bench brings measurement, control, and data analysis together to support structured evaluation of transformer performance in manufacturing, maintenance, and development work.
