UMG 96-PA MID+

Suitable for measuring in all levels of TN & TT networks for recording current, voltage, frequency, active, apparent & reactive power (per phase & total) in the frequency range 45 - 65 Hz, cos phi, active, apparent & Total reactive energy as well as import and export of active and reactive energy (4-quadrant measurement) in separate storage values and 2 tariffs, continuous real effective value measurement (True RMS).

Measurement with commercially available voltage transformers (optional procurement) in medium/high voltage without an artificial neutral point.

For energy data acquisition, power quality measurement and MID-compliant and tamper-proof billing metering. Approved according to EU Directive 2014 32 EU, part MI-003 including initial factory calibration, declaration of conformity & EC type examination certificate (module B + F).

Software separation according to MID guidelines with the possibility of functional extensions through software updates.

Accuracy class B according to EN 50470-1.

Current transformers (optional voltage transformers) approved for billing must be used for MID-compliant measurement.

Sealable terminal covers to create tamper-proof wiring in accordance with MID guidelines.

2 comparator groups for logical evaluation (And / Or, etc.) of 3 direct measured values or resulting measured values with configurable lead time and switch-on time as limit switch (limit value monitoring, etc.) with a cycle of >= 200 ms.

Digital trailing indicator function (positive/negative) of active and apparent power and currents with external synchronization and freely adjustable period (1..166 min.)

Measurement of the positive, negative and zero system as well as the rotating field direction. Total harmonic distortion (THD-I & THD-U), total demand distortion (TDD), individual harmonics (odd) for current & voltage up to the 40th harmonic.

Sampling rate of 8.33 kHz (50 Hz) with 166 measuring points per period (voltage and current measurement) and output of the measured values via the interfaces (cycle >=200 ms).

Tamper-proof separate memory area for MID meter readings of the energy values (15 min. values) for recording measured values over a period of 2 years. Certified meter reading according to PTB-A 50.7.

Representation of purchased and delivered active energy measured values (15 min. interval) in kwh on the display of the entire period with representation of the plausibility (status) of the relevant parameters in connection with time synchronization.

Time synchronization in accordance with PTB-A 50.7 by means of a connection to the PTB time server via NTP (additional Ethernet module required), time synchronization via Modbus-RTU or use of a time pulse on the integrated digital input to ensure that the energy generated and consumed are equal every quarter of an hour.

Configuration change after initial commissioning of the current and voltage transformer ratios as well as the password and the recording of the changes with the associated meter reading in a logbook in accordance with MID guidelines.

Additional 4 MB internal measurement data memory (Flash) freely configurable by the user, clock with buffering.

Expansion option through pluggable function modules.
