ENIP-2 compact

Available ENIP-2 modification in metal housing without voltage measurement inputs - only one phase current is measured. All other inputs/outputs are available. In some cases such set of parameters is required and this modification can be a cost-effective solution.

Compact ENIP-2 in metal body is specially designed for 6 kV – 20 kV switchgear where the key requirements to equipment are the size and the ease of installation.

A single Compact ENIP-2 device can serve as a bay control unit.

Minimal modification is one-phase, current-only, but it still has all three additional voltage inputs.

Compact ENIP-2 measures the complete set of electric grid parameters and is equipped with three additional analog inputs for voltage detection.

Basic modification connects to three-phase current and voltage measuring circuits. It has 12 digital inputs, 3 relay outputs, two serial RS-485 ports, and two redundant 24V DC power supply inputs.
Base configuration

Measurements

  • voltages RMS (phase, phase-to-phase and average);
  • currents RMS (phase  and average);
  • power (active, reactive and apparent: per phase and total);
  • frequency;
  • power factor (per phase and apparent);
  • active and reactive energy in direct and reverse directions.

Power quality

  • voltage sequences;
  • voltage unbalance and distortion;
  • curent sequences;
  • current unbalance and distortion;
  • THD;

Control

  •  Switchgear equipment control using integrated electromagnetic relay outputs and/or using external ENMV-1 telecontrol modules, which are connected to ENIP-2.
  • 12 binary inputs, which allow to monitor switchgear equipment and protection elements status signals;
  • 3 additional voltage inputs for the detection of the presence of voltage on voltage divider insulators in 6–20 kV networks/

Data display

Using external ENMI display modules it is possible to visualize values of main measured and calculated parameters.
