Dr. M. Hor´ a kov´ e 559, 460 06 Liberec 7, Czech Republic E-mail: kmb@kmb.cz, Web: www.kmb.cz Operating Manual for POWER ANALYSER & METER SMY 133 Complete version 2.0 The complete and most actual version of this manual is available online at http://www.KMB.cz/...
General Description The SMY 133 is specially designed for monitoring of energy and power quality in advanced power systems and smart grids. The instrument is designed for installation to the panel. Its graphical display presents advanced information locally without the necessity to use PC. It is suitable for a wide spectrum of automation tasks in modern buildings and industrial plants as well as for power generation and transmission systems.

Installation of the instrument The SMY 133 instrument is built in a plastic box to be installed in a distribution board panel. It’s position must be fixed with the provided locks. Natural air circulation should be provided inside the distribution board cabinet, and in the instrument’s neighborhood, especially underneath the instrument.

In case of successful connection it reads the configuration from the instrument and displays new window with summary information (figure 15).
– For standard instruments with X/5A and X/1A is specified as a ratio between primary and secondary current. Default value is 100 A/5A resp. 1 A. – For SMY 133 options X/100mA and X/20mA a nominal primary and nominal secondary current of the supplied transformer is used. Default value is 100 A/100 mA resp. 20 mA.

Communication Speed — speed (baud rate) of the communication line. Default value is 9600 bps. Communication Protocol — to be chosen between KMB protocol and ModBus RTU. Parity — odd, even or none. Defines behavior of the parity bit control settings.
2.5.5 Inputs & Outputs (fig. 20) SMY 133 could be optionally assembled with 2 relay or SSR outputs and one logical input (RR, RI, II). output controll logic can be programmed into the instrument any output can be configured to provide meter pulse output. In such cases the control quantity can be either active or reactive energy in each quadrant.

Record Name – naming the measurements helps users to identify them correctly during evaluation. For example the transformer or circuit breaker ID could be a good descriptor.
2.5.8 Electricity meter (fig. 23) SMY 133 can be used as a standalone energy meter and register for submetering applications to record four- quadrant active and reactive energies (watt- and var-hour meter). Record Interval: period of creation of the automated meter readings in memory.

The Method of Measurement and Evaluation of Individual Vari- ables Measurement includes three continuously performed processes: frequency evaluation, sampling voltage and cur- rent signals and evaluation of these sampled data. Frequency of the fundamental harmonic voltage component is continuously measured and evaluated every 10 seconds.
