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”

Comparison of Compact Fluorescent to Incandescent Bulbs
Published by Dranetz Technologies, Inc., Case Study With the proliferation of Compact Florescent (CF) lighting, we thought it would be interesting to do a side by side comparison to an incandescent bulb using our new Energy Platform EP1. Not only is it a great demonstration of the capabilities of the EP1 but it’s also an opportunity toContinue reading “Comparison of Compact Fluorescent to Incandescent Bulbs”
Glass Factory Failure of Electronic Controls
Published by Dranetz Technologies, Inc., Case Study The customer was experiencing repeated failures electronic controls and instruments in a new glass factory. The factory had been imported from a 60hz country to a 50hz country. In this case, the new factory capacity was reduced by 50% or more do the frequent shut downs and stoppages. The costContinue reading “Glass Factory Failure of Electronic Controls”
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”

Variable Frequency Drive (VFD) Testing Applications
Published by Dranetz Technologies, Inc. VFD motor controls have become very popular for both retrofits and in new applications. They offer increased energy efficiency, potential for less motor wear, lower startup currents and more. Potential disadvantageous include producing harmonics and damaged motors if they are not controlled properly. VFD’s use a Pulse Width Modulated (PWM) voltageContinue reading “Variable Frequency Drive (VFD) Testing Applications”
Dranetz HDPQ Family Generator & Mission Critical Testing
Published by Dranetz Technologies, Inc. INTRODUCTION Data centers, hospitals, mission critical and other facilities rely on standby power. This is often generators that are ready to carry the load if there is an interruption in the primary power source. Such facilities often have UPS systems for a seamless transition to standby power, and to carry theContinue reading “Dranetz HDPQ Family Generator & Mission Critical Testing”
