1General information
ENIP-2 measures the full set of three-phase electrical grid parameters. It includes RMS of
waveform combinations as well as the 1st harmonic parameters, e.g., effective voltage and
current (each phase and line to line), active, reactive and apparent power (each phase and
total), active and reactive energy import and export, power quality parameters. Digital
input-output and programmable logic functionality enables it to play major role in auto-
mation systems. ENIP-2 is able to exchange data via RS-485 (Modbus and IEC 60870-5-
101 protocols) communication port or Ethernet (Modbus, IEC 60870-5-104 and IEC-
61850 as an add-on option).
ENIP-2 is designed for use in SCADA and supervisory control centers of substations, power
stations, ships, industrial mills, oil and gas production. It can transmit data directly to
higher level of controlling system or through remote terminal unit (RTU), e.g., ENСS-3m,
ENСM-3.
High performance, high-quality signal processing and the possibility of synchronous
measurements of electrical grid parameters make ENIP-2 unique. High-quality measure-
ments are achieved by using our own advanced signal processing algorithms. Moreover,
ENIP-2 optionally supports IEC 61850 (MMS-server, GOOSE subscriber/publisher) and can
serve as a basic control unit for digital substation.
ENIP-2 configuration is supposed to be defined by «ES Configurator»software (here). It
allows to set required parameters for available interfaces and protocols and defining I/O
configuration. For more information, see chapter 6.
ENIP-2 is multifunctional, repairable, restorable device. It is designed for continuous op-
eration in industrial installations.

3.1 General information
Analog current and voltage inputs are converted into analog voltage signals of lower
scale. These signals go to ADC. ADC performs analog-to digital conversion of instantane-
ous values of measured signals (40 measures per each period of industrial frequency
(50/60 Hz)). Measuring data is further passed on to microcontroller (MCU). ENIP-2 struc-
ture scheme is illustrated in fig. 3.1.
MCU performs:
•Electrical grid parameters calculation (using 50 ms “sliding window”measurement
calculation method) –instant measurements;
•Averaging of both measured and calculated parameters through “sliding window”
method (possible averaging time is 200, 500, 1000, 1500, 2000 ms) –averaged meas-
urements;
•Processing digital I/O;
•Data exchange with extension systems through the following protocols: Modbus
RTU, Modbus TCP, IEC 60870-5-104, IEC 60870-5-101, SNTP, SNMP, IEC 61850-8.1 (IEC
61850-8.1 is optional and is sold separately as an add-on).
Galvanic isolation of RS-485 interface is accomplished through interface converters IC1,
IC2, IC3. Built-in functionality of an MCU makes Ethernet port available for use as well.
Real-time clock support is also brought about by MCU.
ENIP-2 might be used for different connections (3- or 4-wire electrical grid, with or with-
out transformers). All wiring diagrams see in Appendix A1.
You can choose the current range needed using «ES Configurator».
Current range
(% of nominal)
Description
1…200%
It’s recommended range. For maximal accuracy ENIP-2 measure in two ranges -
1…70% and 70…200%. Switching between ranges is accompanied by a delay about
200 ms.
2…200%
Fast range. Measurement is provided without switching.
8…800%
Fault current range. Accuracy for low current is does not match the stated accuracy.

tions. Maximum energy value is 99999999.9 Wh (varh). In case of overflow, it starts count-
ing from zero.
