Choosing the right electrical cable size is one of the most important steps in any electrical job. If the cable is too small, it can overheat, trip protection devices, fail short-circuit checks, or cause voltage drop problems. If the cable is too large, the installation becomes more expensive than necessary. A Cable Sizing Calculator removes the guesswork. It… Read More »

Voltage drop is a common issue in electrical installations, and if you’ve ever dealt with dim lights, weak motors, or mysterious performance problems, voltage drop is often one of the first things to check. The good news is that it’s predictable—and with the right tool, you can calculate it in seconds. This voltage drop calculator gives you clear,… Read More »
The digitalization of substations is transforming the way power systems are protected and controlled. Virtual Protection Relays (VPRs) are a major step in this evolution. Instead of using dedicated hardware devices, protection functions now run as software on virtual machines or high-performance computing platforms. This shift is made possible by standards such as IEC 61850-9-2 LE and devices… Read More »
