How New-Energy Box-Type Substations Answer the Same Five Engineering Questions

09-17 2026

Solar and storage sites need more than a standard compact substation. Explore how American-style and European-style box-type substations solve five shared engineering problems — bidirectional duty, inverter harmonics, heat rejection, phased expansion, and unmanned-site safety — in two very different ways.

Reading the Distribution Transformer Nameplate: What Rated Capacity, Voltage Ratio, and Vector Group Really Mean

07-16 2026

A distribution transformer nameplate carries seven critical parameters that determine whether the unit fits your grid or fails on day one. This field guide decodes rated capacity, voltage ratio, vector group, impedance, cooling class, and insulation level — and explains what happens when each is specified incorrectly.
