Transformer

Buchholz relays protect transformers by detecting gas from faults, using floats to trigger alarms or disconnect power, ensuring safety and reliability.

An ideal transformer is a transformer with 100% efficiency, meaning no energy is lost as heat, magnetizing losses, or any other types of losses.

To calculate transformer efficiency, you need to use the formula: efficiency = (output power / input power) x 100%. The transformer's efficiency is impacted by both core losses (hysteresis and eddy current losses) and copper losses. The conditions for maximum efficiency occur when the copper losses equal the core losses.

Explore the fundamentals of generators, transformers, and motors—how they work, their core principles, and the key differences that make each unique.

Discover the key reasons behind transformer humming, from magnetostriction to loose components and harmonic frequencies, and understand the underlying causes.
