How Is Electricity Generated? From Energy Source to Power Grid
Electricity is generated by converting another form of energy into electrical energy. In most power plants, heat, falling water, wind or an engine first creates mechanical rotation. That…
MPPT Algorithms in PV Systems: How They Work and Compare
A maximum power point tracking (MPPT) algorithm controls the electrical operating point of a photovoltaic array so the connected converter can extract as much available DC power as…
Motor Protection Circuit Breaker Design Basics
A motor protection circuit breaker (MPCB) is a low-voltage switching and protective device designed around motor-circuit behavior. It typically provides adjustable overload protection, rapid short-circuit protection, and manual…
Current Chopping in Vacuum Circuit Breakers: Why It Causes Switching Overvoltage
Current chopping is the premature extinction of alternating current before its natural current zero. In a vacuum circuit breaker, a small inductive current may become unable to sustain…
Solid vs. Stranded Wire in Terminal Blocks: Selection and Termination
Use solid wire in a terminal block when the terminal explicitly accepts the conductor size and the installed wire will remain essentially static. Choose stranded or flexible wire…
Top 10 Power Transformer Manufacturers in 2026: A Data-Based Global Ranking
Hitachi Energy ranks first in OHELE’s 2026 assessment of global power transformer manufacturers, followed closely by Siemens Energy and GE Vernova. TBEA leads the next group, while HD…
UL Terminal Blocks for U.S. Equipment: A Compliance Selection Checklist
A UL Recognized terminal block is a component evaluated for use inside a larger end product under stated conditions. It does not, by itself, make an industrial control…
Cable Sizing for Circuit-Breaker-Protected Feeders: Six Verification Gates
For an LV feeder protected by a circuit breaker, choose a cable whose corrected current-carrying capacity covers the load and the breaker’s effective overload setting. Then verify voltage…
MV Disconnectors and Earthing Switches: An IEC 62271-102 Selection Guide
Select a medium-voltage disconnector to establish the specified isolating condition after another device has interrupted the load. Select an earthing switch to connect an isolated circuit to earth…
Compact Switchgear Busbar Sizing: A Thermal Verification Workflow
To size a busbar for compact low-voltage switchgear, choose a preliminary copper area from the continuous current, calculate hot conductor and connection losses, place those losses in the…
