Siemen’s – Harmonic Solution Guide

Power quality solutions for line side harmonic distortion with Siemens’ VFDs What are Harmonics? Harmonics can be best described as the shape or characteristics of a voltage or current waveform relative to its fundamental frequency. But what does that mean? Well, the ideal power source for all power systems are smooth sinusoidal waves. These perfect… Read more »

Siemens – IEEE-519 Harmonic Mitigation Guidelines

How Siemens’ Customers Can Meet IEEE-519 Guidelines IEEE-519 is a system guideline for setting limits on voltage and current distortion. This document outlines the changes in IEEE-519 relative to harmonic mitigation. ABOUT IEEE-519 2014 REVISION The last version of the IEEE-519 standard is from 1992. Overall, the 2014 version has been simplified when compared to… Read more »

Siemens – Motor Protection Guide

Load-side solutions for power quality in systems using Siemens’ Variable Frequency Drives How Variable Frequency Drives (VFDs) Work VFDs serve as a way of controlling the speed of AC motors by varying the frequency of the power source using pulse width modulation (PWM). This is done by switching the transistors, IGBTs, or thyristors, on and off… Read more »

Siemens – Common Mode Overview and Reduction Guide

Customer’s using Siemen’s VFDs Can Understand How to Reduce Common Mode To start off, common mode is bad. Common mode voltage is created by Variable Frequency Drives (VFDs) that serve as a way of controlling the speed of AC motors by varying the frequency of the power source using pulse width modulation (PWM). This is done by switching the… Read more »

Siemens – Motor Bearing Protection Guide

Customers Using Siemen’s VFDs can benefit from the dV Sentry™ filter A common method across industries is to use a shaft grounding brush or ring to protect motor bearings from common mode over voltage. A shaft grounding brush is not a filter, so it does not help reduce or protect equipment from the actual problem. The current is detected… Read more »

Using a Passive Sinewave Filter to Eliminate Common Mode and Differential Mode

An integrated output filter that eliminates motor problems due to the PWM waveforms in both common mode and differential mode operation is proposed. The filter includes a three phase inductor constructed with tricore laminations with six mutually coupled windings. The windings possess differential mode inductance and proportionally very large common mode inductance characteristics. The single integrated inductor with the capacitors creates a…
