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”
