OVERVIEW

The RDCR5000 power quality measurement equipment is a sophisticated testing device crafted for on-site evaluation of three-phase systems. It’s a versatile and intelligent instrument that simplifies human-machine interaction, ensuring ease of use. The analyzer features a large LCD screen with high resolution, offering clear visuals, and supports both Chinese and English interfaces. Its robust, shock-proof shell is designed to withstand the rigors of fieldwork.

The RDCR5000 is capable of simultaneous measurement across four current channels (including ABC phases and neutral current) and four voltage channels (ABC phase voltages and neutral-to-ground voltage). It accurately captures peak current and voltage values, as well as maximum and minimum values over a given period. The power quality measurement equipment assesses three-phase imbalance factors, short-term voltage flicker, transformer K factors, and a range of power parameters including active, reactive, and apparent power, power factor, displacement power factor, and total harmonic distortion.

In addition to these measurements, the RDCR5000 displays real-time waveforms and harmonic ratio bar charts for both current and voltage. It can dynamically detect instantaneous changes in voltage and current, monitor starting currents, and keep a watchful eye on power parameters, generating an alarm list and trend charts for long-term recording and analysis of test data.

CHARACTERISTIC

1. The analyzer features a dual-processor architecture with both DSP and ARM chips. The DSP is dedicated to data collection and algorithm processing, while the ARM handles communication protocols and man-machine interface processing.

2. Analog signal acquisition is facilitated by two AD7655 chips from ADI, offering a 16-bit resolution and supporting 4-channel synchronous sampling. The maximum sampling rate of 1 MSPS ensures channel accuracy and data integrity, allowing for precise detection of transient changes in the grid, such as abrupt rises and falls in waveforms and instantaneous interruptions.

3. The DSP operates at a frequency exceeding 200 MHz, enabling real-time monitoring of the power grid and dynamic adjustment of the sampling frequency to achieve synchronization with the power frequency.

4. A 5.6-inch LCD color screen with a resolution of 640 dots x 480 dots is used for display. It can represent parameters such as phase, waveform, vector diagram, and harmonic ratio with different colors, enhancing the efficiency and intuitiveness of understanding the power grid’s state.

5. The built-in flash memory can store up to 60 groups of screenshots, 150 groups of transient voltage/current waveform figures, and 12,800 groups of alarm lists simultaneously. The starting current detection model is capable of continuously capturing the starting current waveform for 100 seconds.

6. An integrated 2G memory card is used to store trend curve records, which can simultaneously record data for 20 parameters (selectable as needed) every five seconds. The trend curve records can be stored for up to 300 days.
