Practical 400 Hz use Cases for Aviation Teams

Published by Dranetz Technologies, Inc. Below are three situations aviation teams often face, and how the HDPQ Xplorer 400 helps resolve them. Jetway keeps resetting when an aircraft connects What’s happening: During bridge movement or aircraft power-up, the 400 Hz supply dips. Sometimes it is a brief sag, other times a fast transient that trips protection.Continue reading “Practical 400 Hz use Cases for Aviation Teams”

400Hz Monitoring – Aviation Applications

Published by Dranetz Technologies, Inc., Application Note INTRODUCTION Most of the world distributes power at 50Hz or 60Hz. However, there are certain specialized applications that distribute power at other frequencies. Applications such as aviation, naval, and others distribute power at 400Hz to improve system efficiencies. 400Hz applications can be a challenge for the end user since mostContinue reading “400Hz Monitoring – Aviation Applications”

The Critical Role of Power Quality Evaluation in Solar Installations

Published by Dranetz Technologies, Inc., Application Note EXECUTIVE SUMMARY As solar photovoltaic (PV) systems become more prevalent in commercial and industrial environments, the emphasis on financial return and concise performance expectations has rightly intensified. However, one often-overlooked aspect of solar deployment is the comprehensive evaluation of power quality (PQ)—both before and after installation. By identifying existing gridContinue reading “The Critical Role of Power Quality Evaluation in Solar Installations”

Planning and Performing a Power Quality Survey

INTRODUCTION The power quality survey is the first, and perhaps most important, step in identifying and solving power problems. Power problems can harm equipment performance and reduce reliability, lower productivity and profitability, and even pose personnel safetyContinue reading “Planning and Performing a Power Quality Survey”

Understanding Telephone Interference Factor

Published by David Horning, March 2013. Power Monitors, Inc., White Paper: Understanding Telephone Interference Factor Abstract. Harmonic distortion that is produced from power conversion systems can cause interference on analog telephone lines. The degree of telephone interference can be expressed in terms of the Telephone Interference Factor (TIF). This white paper will discuss how interference isContinue reading “Understanding Telephone Interference Factor”

Steps to Find the Source of Harmonics

Published by David Horning, November 2014. Power Monitors, Inc., White Paper: Steps to Find the Source of Harmonics Abstract. Harmonics are “Non-Linear” current or voltage in an electrical system. Any waveform that deviates from a perfect sine wave has harmonics. Any nonlinear load draws harmonic currents and therefore produces harmonic voltage distortion, by producing non-sinusoidalContinue reading “Steps to Find the Source of Harmonics”
