I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

Battery cell voltage is the most fundamental measurement made on the cell. While on the surface measuring voltage seems easy, ...

Researchers from Pakistan's Ghulam Ishaq Khan Institute of Engineering Sciences and Technology have created an online algorithm to measure open-circuit voltage in PV systems that is claimed to be able ...

Common traits of digital multimeters (DMMs). Classifying DMMs by their amount of digits. What role do digitizers play in making voltage measurements? Measuring voltage may be the most basic ...

Table 100.19 from ANSI/NETA MTS-2011 provides recommended test voltages for proof testing and field testing medium-voltage power circuit breakers and switchgear. These three tests should be in your ...

Every year, we read about electricians, engineers, and supervisors who were seriously burned or killed while working in or near a circuit breaker (CB) compartment. I’ve personally investigated ...

Scientists at Germany's Fraunhofer Institute for Solar Energy Systems ISE have demonstrated a triple-junction solar cell with a perovskite-perovskite-silicon subcell configuration. They said the cell ...

If a poll was taken to determine what aspect of the hot rod hobby enthusiasts dislike the most, there’s a high likelihood that “diagnosing electrical issues/gremlins” would be the popular answer. An ...

JA Solar’s Bycium+ cell has achieved a significant breakthrough, reaching a new high in cell efficiency and setting a new record with an open-circuit voltage of 748.6mV – the highest in the commercial ...

One characteristic of adding PV solar to homes is a massive increase in high-voltage and high-current DC installations. With this comes a need for suitable breakers, but without the requisite ...
