Distribution transformer with load schedule, calculator and electrical measuring instruments

Vollständiger Leitfaden zur Transformatorbemessung und -berechnung

Die Dimensionierung eines Transformators ist mehr als nur das Teilen der Gesamtlast durch einen Prozentsatz. Eine zuverlässige Auswahl rechnet die Reallast in kVA um, berücksichtigt Bedarf und Gleichzeitigkeit, prüft Motoren und Oberschwingungen, berücksichtigt die Umgebung und die Zukunft…

High-voltage transmission lines entering a substation with power transformer

Vollständiger Leitfaden zur allgemeinen Elektrotechnik

High voltage allows electric power to move long distances with lower current and lower conductor losses, but it also increases insulation, clearance, protection and safety requirements. This guide explains what voltage…

DIN-rail miniature circuit breakers installed in an industrial distribution panel

Leitungsschutzschalter: Ein Leitfaden

Ein Leitungsschutzschalter, formeller ein Kleinleistungsschutzschalter (MCB), schützt Niederspannungs-Endstromkreise vor Überlast und Kurzschluss. Er kann nach Behebung des Fehlers zurückgesetzt werden, muss jedoch ausgelegt sein für…

Utility substation transformer feeding indoor electrical distribution switchgear

Complete Guide to Power Distribution System Design

An electrical distribution system transfers power from a utility connection or generator through substations, transformers, switchgear, panels and cables to the final loads. Good design delivers acceptable voltage,…

Three-phase step-up transformer connecting low-voltage switchgear to higher-voltage substation equipment

Step Up Transformer: Guide

A step-up transformer raises alternating voltage from the primary side to the secondary side. For approximately the same apparent power, the higher-voltage side carries lower current. Step-up units connect generators…

Power transformer and switchboard with electrical measuring instruments and calculator

Complete Guide to Electrical Calculations & Conversions

Converting kVA to amps is one of the most common calculations in transformer, generator, cable and switchgear selection. The arithmetic is simple, but the result is only correct when the phase arrangement and voltage…

Power factor correction capacitor bank installed beside an industrial switchboard

Power Factor Correction Capacitor: Guide

A power factor correction capacitor supplies reactive power close to an inductive load, reducing the reactive current drawn from the utility. Correctly applied, a capacitor bank can lower current, release transformer…

Electrical substation with power transformer busbars circuit breakers and disconnectors

What Is A Substation?

What is a substation? An electrical substation is a controlled point in a power system where electricity is transformed, switched, protected, measured, and routed. It connects generation and transmission networks to…
