Main measurement

UMG 511 has 4 measuring channels for current and tension. The first three channels (measurement of a base line) are held for use in a three-phase system.

Auxiliary measurement

Auxiliary measurement can be used for measurement of a single-phase or symmetric three-phase system. Alternatively, the input on current can be selected to the three-phase system of measurement of a base line for measurement of current in a neutral. Tension input, for example, can be used for registration of tension between N and PE. Auxiliary measurement represents all parameters of measurement as well as in measurement of a base line (current, tension, power, harmonics, transition processes, events and a dose of a flicker...).

Interfaces

• RS485 protocols: Profibus DP or Modbus/RTU, Modbus-Gateway and BACnet
• Fast Ethernet 10/100Base-TX protocols: HTTP, NTP, Modbus TCP, Modbus through TCP, DHCP and BACnet

The measured values and the written data can be schitana through Ethernet (TCP/IP). The configuration of the device and data analysis is made using the software of GridVis which is included in the delivery. By means of network protocols (Modbus/RTU, Modbus/TCP, Profibus) there can be schitana the real measured values and be exercised control of digital inputs and exits. The maintenance of digital inputs and exits can be used for different tasks.

Application

The analyzer of quality of power is equipped with 4 measuring inputs on current and tension, measures and digitizes effective values of currents and tension in network of 50-70 Hz. The built-in microprocessor calculates electric parameters from values of selection. The corresponding tension can be determined as linear or phase stress for measurement in a three-phase system.

Tension given on UMG 511 is used as reference voltage for measurement of harmonic composition, transition processes, records of events and calculation of a dose of a flicker. For record of current events it is necessary to set rated value of current.

The 4th measuring input of current and tension represents the separate system of measurement. Usually this input is used to measure current in neutral or PE the conductor or used to measure the difference of tension between N and PE.

The added values by means of additional functions.

The UMG 511 analyzer of quality of power is used for the purpose of continuous quality control of power, for example according to EN 50160. Also serves for the purpose of quality control of power of power supply from a power source.

Data collection and record

UMG 511 has an internal memory on 256 MB for continuous registration of all measured data. Memory of the measured values is freely configured concerning the choice of the measured values which should be written also intervals of record. A record interval - the average time of the corresponding measured value. Besides, the maximum and minimum effective values (time of averaging of 200 ms) can be saved within these intervals if you want to save data as the diagram of y (t). It is also possible to save these measurements in the form of histograms (distribution curve).

Registration of transition processes and events is defined by triggers. Transition processes are registered with the period of more than 50 microsec. Events, such as, jumps of current, voltage drop or overvoltage can be safely saved for a half-cycle. Events are registered with more than 16000 (is programmed) by half-cycles.
