KN-613 Online Power Quality Monitoring Device

The KN-613 Power Quality Online Monitoring Device features a 4U/19-inch standard cabinet design and a 6.4-inch true-color large LCD display.

Screen display, capable of simultaneously monitoring power quality data for multiple voltage and current segments, expandable to eight voltage segments, eight current segments, each segment

Voltage and current are sampled using a separate 16-bit A/D converter and independently calculated. Any fault in a segment of voltage or current will not affect

His sampling and analysis of voltage and current has an impact. Fully meets the requirements of 7 national standards, equipped with RS485/RS232 and Ethernet communication.

Function. Below, we will specifically introduce online monitoring of power quality.

The online power quality monitoring device functions as follows:

Basic Measurement Sizes

Power grid frequency; RMS voltage and current; Total active, reactive power and power factor.

Basic Monitoring Indicators

① Three-phase fundamental voltage, current RMS values, fundamental power, power factor, phase, etc.

Voltage Deviation.

③ Frequency Deviation.

④ Three-phase voltage unbalance, three-phase current unbalance, negative sequence voltage, and current.

⑤ Harmonics (2-63 times). Including total harmonic distortion rate of voltage and current, harmonic content rate of each order, amplitude, and phase.

Each harmonic's active and reactivePower ratings, etc.

★ Advanced Monitoring Indicators

Interharmonics.

② Voltage surges, drops, and short interruptions.

★  Display Function

The device panel features a large-screen LCD display, graphically displaying real-time data of the main electrical power quality monitoring indicators.

★  Setup Function

The device's hardware clock can be set, monitoring parameters can be configured, modified, and viewed, and it features password protection.

Communication Features

The device offers various communication interfaces for real-time transmission of monitoring data, and can be connected via industrial Ethernet interface to remote locations.
