Published by Dranetz Technologies, Inc., Technical Documents he HDPQ Family of products have a number of trigger mechanisms for capturing different types of power quality phenomena. Most users are familiar with settings for sags and swells, but those typical limits usually don’t capture the “blinky lights” problems. While the Pst (perceptibility short term) parameter will indicate whether the voltageContinue reading “Investigating Blinky Lights”

Overloaded Service
Published by Dranetz Technologies, Inc., Case Study A busy trading floor was experiencing difficulties with their six air handling units, which were fed from a single 480V, 400-amp service. The units were malfunctioning, stalling and at times were unable to start, causing the temperature in the control room to rise to unacceptable levels. A Dranetz Power PlatformContinue reading “Overloaded Service”
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”
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”
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”
PQ Analysis: Power Quality Reports
Published by testguy, November 23, 2019. Website: testguy.net Power Quality Reports A power quality meter can plot the voltage and current waveforms as functions of time, this is called an oscillogram. Data can be extracted from the power quality recorder and analyzed to determine the overall condition of the power system using various timeplots and tables. TheContinue reading “PQ Analysis: Power Quality Reports”
