Harmonic Calculations
In a normal distribution network, the fundamental frequency is that of the voltage driving source, nominally 60Hz. Steady state deviations from the ideal 60 Hz sine wave shape are “periodic,”…
Seeker Modbus Map
The Seeker power quality recorder includes a variety of mechanisms to retrieve measurements. One of is Modbus, a protocol often used for communication with industrial electronic devices. The protocol is…
Interharmonic Analysis with Python
Traditional harmonic analysis in electrical systems has revolved around looking at the spectral content on, well, the magnitudes of harmonic frequency components. The IEEE 519 specification provides guidelines for measuring…
ProVision Recording Templates
This white paper covers the creation and use of predefined recording templates in ProVision. PMI recording devices can be initialized with a number of configurable settings. Configurable settings include recording…
CBEMA-ITIC Analysis with Stripcharts
The ITIC curve (formerly CBEMA) is a performance-oriented standard for electronic equipment manufacturers. The standard gives a method for classifying and plotting voltage events on a specially constructed graph that…
Understanding RMS Measurements
Power Monitors, Inc. provides a wide array of power quality test instrumentation. These devices are used to measure line voltage, current and power from or to a number of different…
Electrical Undervoltage and Power Quality
In this whitepaper, the term undervoltage is explained, some typical causes of undervoltages are given, and the effects of undervoltage on customer loads is described. IEEE 1159-2009, IEEE Recommended Practice…
Hardware for Power Quality and Distribution Monitoring
PMI offers an array of monitoring devices for just about any utility distribution monitoring need. Data needs, location, and communications requirements are all factors involved in selecting the right monitor…
Understanding PMI Data Record Types – Part 2
The job of any power monitor is to record all interesting data, and leave unrecorded the vast majority of boring, unremarkable data. The tricky part for a monitor is deciding…
