Energomonitor 61850

Reference instrument of new generation meant for testing of non-conventional (electronic and digital) current and voltage instrument transformers and Merging Units.

DESCRIPTION:

Reference instrument of new generation meant for testing of non-conventional (electronic and digital) current and voltage instrument transformers and Merging Units.

Purpose

  • Measurement of ratio and angular errors of current and voltage scaling converters (electronic and digital instrument transformers) with analogue outputs or digital (Sampled Value) outputs according to IEC 61850-9-2LE

  • Determining accuracy characteristics of Merging Units (IEC 61869-13)

  • Measurement of current- and voltage-related quantities with further conversion into IEC 61850-9-2LE compliant data streams

  • Energomonitor-61850 itself constitutes a reference Merging Unit

Key components

  • 4 multi-range input current converters (0.01…100A)
  • 4 multi-range input voltage converters (0.01...800V)
  • 8-channel ADC
  • Control unit based on a built-in single-board computer and Wi-Fi access point
  • Synchronization unit (PPS/PTP/10 MHz/20 MHz)
  • Power Supply Unit
  • External PC or tablet (Microsoft Windows or Android)
