[Technical Articles] Amorphous-Core Transformers: The Materials Science Behind Ultra-Low No-Load Loss
11-13-2026

An amorphous-alloy core cuts transformer no-load loss to roughly one-third of grain-oriented silicon steel — but only because a 25-micron ribbon is frozen so fast it never crystallizes. This guide explains the material physics, the five engineering trade-offs (noise, short-circuit, clamping stress, core size, cost), and where the lower loss actually pays back. Read More
[Technical Articles] Dry-Type Transformer Condition Monitoring in Offshore Wind: Catching Salt-Fog Degradation Before It Fails
11-05-2026

A dry-type transformer in an offshore wind nacelle does not fail without warning — if anyone is watching. This guide covers the condition-monitoring toolkit (online partial discharge, thermal, humidity, insulation-resistance trending), the salt-deposit inspection cadence, failure-prediction logic, and a maintenance plan that prices in the cost of a vessel trip.

[Industry Information] Dry-Type Transformer Ventilation and Heat-Dissipation Engineering: How to Size the Room, the Openings, and the Fans
10-30-2026

A dry-type transformer's real capacity is decided by the room around it, not just the nameplate. This guide gives the ventilation-area and forced-airflow calculations, the recirculation trap, clearance rules, and altitude/ambient derating — with a worked example and a procurement checklist.

[Technical Articles] The Distribution Transformer in the Bidirectional Grid: New Demands EV Charging and Distributed PV Place on a Unit Built for One Direction
10-21-2026

A distribution transformer designed for one-way power flow now faces two opposing loads at once: evening EV charging peaks and midday rooftop-solar export. This article lays out the new engineering demands — wider voltage regulation, bidirectional tolerance, harmonic duty, and a data interface — and what to specify. Read More
