Handheld Power Quality Analyzer (three phase) Analizador De Red Electrica High Precision Power Meter

KDZD5000 Basic Function Introduction:

Test function: Real time waveform display (4 voltage/4 current channels); True effective values of voltage and current; Voltage DC component; Peak current and voltage; The maximum/minimum values of current and voltage over a period of time; Phasor diagram display; Measurement of harmonics in each phase, up to 50 harmonics; The bar chart displays the harmonic ratio of each phase current and voltage; Calculation of Total Harmonic Distortion (THD); The active/reactive/apparent power values and total values of each phase; The active/reactive/apparent electrical energy values and total values of each phase; Transformer K-factor calculation; COS φ Calculation of displacement power factor (DPF) and power factor (PF); Flash calculation; Calculation of three-phase imbalance (voltage and current)

Capture and monitoring functions: It can capture and detect instantaneous changes in the voltage and current parameters of the power grid, including voltage and current fluctuations, voltage and current surges, drops, short-term interruptions, transient overvoltage, surg
e current, and instantaneous distortion of current and voltage. The instrument can store up to 150 sets of transient waveforms simultaneously.

Start current monitoring: It can monitor the surge current of the circuit and the starting current of electrical equipment during startup, which helps to design the installed capacity correctly. It can display the rise/fall curve of the effective value during the startup process, the envelope curve of the startup current, and the waveforms of four currents and four voltages. After triggering, it can record for about 100 seconds, storing all instantaneous current and voltage values and waveform curves for each cycle within 100 seconds.

Record storage function: All testing parameters for basic testing functions (Urms, Uthd, Ucm, Uub, Hz, Vrms, Vthd, Vcm, Vub, PST, Arms, Athd, Acf, Aunb, KF, W, VAR, VA, PF, COS) can be tested φ, TAN φ), Record 123 parameters of voltage 50th harmonic and current 50th harmonic, and generate trend curves. Long term data recording can be performed as needed. (Selecting 20 parameters at the same time and recording them every 5 seconds can record for approximately 300 days.)

Alarm function: The selected parameters can be set with limit values as needed to monitor whether they exceed the limit. When they exceed the limit, an alarm log will be generated, such as voltage overvoltage, current overcurrent, imbalance exceeding the limit, a certain harmonic ratio exceeding the limit, frequency exceeding the limit, active power exceeding the limit, total harmonic distortion exceeding the limit, etc. Up to 40 sets of alarm monitoring parameters can be set, and each set can set different monitoring parameters (including 123 different parameters for 50 harmonics) and limit values, The shortest time for exceeding the limit can be set. Up to 12800 sets of alarm log records can be stored.

Screenshot function: On the testing page, you can take a screenshot and store the current screen image, while automatically saving the recorded time and the testing mode. Such as saving current and voltage waves, harmonic bar charts, phasor diagrams, etc. Up to 60 sets of screenshots can be saved simultaneously.

Communication function: By communicating with the computer via USB, the monitoring software can display real-time waveforms of power quality analysis tests, and can read transient waveforms, trend chart records, alarm lists, test screenshots, etc. detected and captured.
Setting functions: Users can set the time and date, set the contrast and brightness of the display screen, and set the corresponding colors of each phase line in the instrument; Can set the wiring method and power grid type of the instrument; Different current clamps and voltage test ratios can be selected; You can choose between Chinese or English menus.
