Panel-Mount Power Network Analyzers

A panel-mount power network analyzer is a multifunction measuring instrument that is flush-mounted in the panel door and shows the current, voltage, power, energy and, depending on the model, harmonic values it measures on its display. It is used in main distribution, power factor correction and generator panels so that values can be read without opening the door and data can be transferred to a monitoring system over communication. The category includes the 96 × 96 mm Entes MPR and EMR series and the Tense TPM series; for Tense models, the display type is given as 7-segment LED, graphic LCD or color TFT, and harmonic measurement is given up to the 31st, 41st or 63rd harmonic. Compare the supply voltage (for example 24-60 V AC/DC or 100-270 V AC/DC) by the auxiliary voltage in the panel, and the harmonic measurement depth, accuracy class, RS-485 communication and the number of relay, digital input and pulse outputs by the needs of the measurement point. For some Entes models, the 0.5 accuracy class is also stated in the product name. A power network analyzer measures and displays; it is not a substitute for the reactive power control relay that switches capacitor steps.

  • Take reactive power demand and harmonic distortion levels from site measurements or project calculations.
  • Compare kVAr step sizes, rated voltage and step count against the compensation panel layout.
  • Select capacitor duty contactors, harmonic filter reactors and discharge resistors together with the capacitor bank.
