Today, compressor overheating is one of the HVACR industry’s most serious field problems. Compressor overheating is usually caused from high compression ratios. High compression ratios can be caused ...

Welcome to the first in a series of articles focusing on electrical calculation basics. This month, we'll discuss the most fundamental of calculations — those for current (I) and kilowatts (kW). We'll ...

There are many reasons why one would want to measure voltage and current in a project, some applications requiring one to measure mains and even three-phase voltage to analyze the characteristics of a ...

Having both 3-phase and single-phase loads can be challenging when trying to balance the voltages at a facility. It’s possible that during a facilities operation, one phase can be lightly loaded ...

The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is defined using the space vector modulation (SVM) ...

The National Electrical Manufacturers Association has published ANSI C12.20-2010 American National Standard for Electricity Meters—0.2 and 0.5 Accuracy Classes. Oct. 18, 2010 The National Electrical ...

Lincoln Electric and Edge Energy are bringing DC fast charging with speeds of up to 100 kW to sites WITHOUT 3-phase power.

Traditional 12V to 48V motor drive systems typically use an MCU paired with three separate gate drivers. However, rising demand for higher efficiency and more precise control is accelerating the shift ...
