Magnetic aging is a natural performance attenuation phenomenon of electrical steel after long-term operation. It will gradually reduce the comprehensive performance of transformer equipment.

Magnetic aging firstly causes continuous rise of transformer no-load loss. Internal magnetic domain stability of aging steel decreases. Hysteresis loss increases year by year. Long-term accumulated energy consumption rises obviously.

It reduces core magnetic induction and anti-saturation ability. Aging changes microscopic grain structure. The maximum magnetic flux bearing capacity declines. Transformers are more prone to magnetic saturation under peak load.

It aggravates transformer operating temperature rise. Increased loss converts into more heat. Long-term slight overheating accelerates insulation aging. It shortens the overall service life of equipment.

It increases transformer operating noise and vibration. Aging steel has unbalanced magnetic domain movement. Magnetostriction vibration intensifies. Equipment noise becomes louder with service time.

It leads to unstable power supply performance. Aging-induced loss fluctuation causes unbalanced magnetic flux. Transformer output voltage waveform distorts slightly. It affects power supply stability.

High-quality anti-aging electrical steel can slow down this process. HiB laser scribed steel has purer internal structure. Its magnetic aging speed is far lower than ordinary CGO steel.

Regular equipment maintenance delays aging deterioration. Timely heat dissipation and dust removal stabilize core working environment. It reduces magnetic performance attenuation rate.

In conclusion, electrical steel magnetic aging causes multi-dimensional transformer performance degradation. Selecting high-grade steel and daily maintenance effectively control aging risks.
