Power companies provide us with a mains voltage of 220 volts ±10% and frequency 50±1 Hz, sinusoidal, in accordance with GOST 13109-97... If you believe that, you are very naive. What is the network they serve, actually, only they know themselves. And energy user ought to know.
And the user can be equipment that is great is ruining the network by the so-called cosine Phi, and he that does not know. For it sometimes fined in exorbitant sums.
What do you do after all control devices and network analysis are quite expensive, but they are not required so often? Yes, and to work with them is not easy, we need some preparation. One possible way is to appeal to those who such devices are already acquired and mastered. For example, to us.
We have the devices and professionals who know how to use them. You talk about your electrical system all you wanted to know but were afraid to ask. The voltage consumed active and reactive power, cos Phi, the degree of harmonicity-and much, much more.
Believe me, to know is sometimes beneficial, and ignorance of the responsibility, as you know, is not exempt.
Device C. A 8335 (Qualistar+) (hereinafter – Pribor.And 8335) is a three-phase graphical analyzer of parameters of the power network with AC+DC 1000 ВRMS, measuring category III or 600 ВRMS measurement category IV in accordance with the standard (IEC 61010-1). He performs a triple role. 1. A quick assessment of operating network parameters (electrical values of the mains power obryv circuit) 2. Provides instant display of the main parameters of 3 phase network. Control changes different network settings in a long time the Error of the instrument CA 8335 is more precisee 1% (the error of the current sensors is not included). In addition, the device demonstrates great flexibility when selecting various sensors for the measurement of hundreds of milliamperes (MN93A) to several kiloamperes (AmpFLEX™). The device is compact and has high impact resistance. Ergonomic and easy user interface make it easy and convenient to use. The device is designed to CA8335 energy and operational departments of industrial and administrative buildings and instantly gives a picture of the major characteristics of the mains, which are supplemented by calculated values and numerous processing functions the Device performs a number of basic dimensions, such as: 4. The values of the variable voltages up to 1000 V between terminals 5. Values of AC current up to 6500 Ampswith (no wire included) 6. Measurement values of voltage and current (ground wire included) 7. Measurement of the minimum and maximum values of voltage and current half cycle 8. The peak values of voltage and current (neutral wire not included) 9. Measurement of the mains frequency in 50 Hz and 60 Hz. 10. The ratio of the amplitude of current and voltage (crest factor) (zero wire not included) 11. Calculation of K-factor current (KF) (using the transformer in the presence of a harmonic current component) 12. Harmonic factor (DF) for current and voltage (neutral wire not included) 13. Total harmonic distortion for voltage and current (neutral wire not included). 14. Active, reactive (capacitive and inductive) and apparent power of individual phase and all phases (neutral wire not included). 15. The calculation of cos j the power factor (DPF) and power factor (PF) (neutral wire not included). 16. The calculation of the short-term jitters (flicker) voltage (PST) (neutral wire not included). 17. Active, reactive, and transmitted energy; the total energy (ground wire not included). 18. Harmonics up to 50th order and the voltage (neutral wire not included): RMS value, percentage relationshipe, values for the minimum and maximum harmonic component. 19. Measurement, calculation and display of harmonics up to the 50th order with their phase information values, percentage, values for the minimum and maximum. 20. Motor starting current
This graphic LCD display with screen resolution at 320x240 pixels with backlight shows measured device parameter values associated with the curves, if necessary, you can select curves that instantly evaluates the signal and selects the type of measurement. When starting the measurement, the meter C. A 8335 screen automatically displays the "Waveform" (the waveform) Modes of the device. The display of transients: waveform, inrush currents, the Curves display related to the 24 harmonic for each phase is measured in percent total harmonic distortion (THD) for U,I,W, VA, as well as measured eff. the value and phase shift of the harmonics, as well as an analysis of the problems created by harmonics according to their range (heated, zero wires, conductors, motors...) Show waveforms of voltage and current, display of the minimum and maximum values, summary tables, determination of phase sequence alarm Mode: list 41тревог, was according to the thresholds programmed during configuration, check the network fuses with a resolution of half life (VRMS, URMS, URMS), determination of the over-consumption of energy, control in accordance with the contract quality of supply. Mode Trend: registracija overload selected in the Configuration Menu Displays measurements related to power and energy connecting the device to the network according to the following schemes
