PQMII-T20-C-A Three phase Power Quality Monitor

Description

PQMII-T20-C-A is an advanced three-phase power quality monitoring instrument designed to seamlessly integrate with the industrial control system ecosystem. Its function is achieved through continuous measurement and analysis of a comprehensive set of electrical parameters. By utilizing advanced sensors and signal processing algorithms, it is able to capture data such as voltage, current, frequency, power factor, and harmonic distortion (up to high order, such as 50th order) in three phases.

PQMII-T20-C-A

The monitor obtains raw electrical data through current transformers (CT) and voltage transformers (VT). After data collection, it is processed internally and available for further analysis. In industrial environments, it can easily integrate with programmable logic controllers (PLCs), monitoring and data acquisition (SCADA) systems, or other power management platforms. Communicate seamlessly with the central control station through popular industrial protocols such as Modbus TCP/RTU.

This module has multiple configurable outputs, including relay outputs, which can be set to trigger alarms or initiate corrective actions when power parameters deviate from preset thresholds. For example, if the voltage drops below a certain level or harmonic distortion exceeds acceptable limits, the relay can be programmed to send an alarm to the maintenance team and even activate the backup power system. It also has analog outputs, such as 4-20 mA signals, which can be used to interface with other analog based control devices or for further data recording.

PQMII-T20-C-A

Main features and advantages:
Its high-precision measurement (voltage and current accuracy of ± 0.5%) can achieve accurate energy auditing. By accurately tracking electricity consumption, the industry can identify inefficient areas and implement targeted energy-saving measures. For example, a large manufacturing plant may find that certain production lines consume excessive reactive power. With the insights provided by PQMII-T20-C-A, they can install power factor correction devices that may reduce energy costs by up to 15%.

The real-time alert system is a significant change in reducing unplanned downtime. In data centers, a sudden voltage spike may damage servers and interrupt services.PQMII-T20-C-Acan detect such anomalies within milliseconds and immediately trigger alerts through email, SMS, or SCADA notifications. This enables IT teams to take swift action, such as switching to backup power sources or adjusting power distribution systems, thereby reducing the risk of costly power outages.

This monitor can store historical data for a long time, which is very valuable for predictive maintenance. By analyzing the trend of power quality over a period of time, the maintenance team can predict equipment failures. For example, if the harmonic distortion level of an electric motor gradually increases, it may be a sign of impending mechanical or electrical problemsPQMII-T20-C-Acan achieve proactive replacement or repair, saving time and money in the long run.

Application areas:
Manufacturing industry: In automotive manufacturing factories, PQMII-T20-C-Acan be deployed to monitor the power supply of automated assembly lines, robot welding stations, and paint spraying robots. Accurate power quality monitoring ensures that high-precision operations are not interrupted by power fluctuations. For example, it can detect and correct voltage imbalances that may cause uneven welding of car bodies, improve product quality, and reduce scrap rates.
Energy industry: In power generation facilities, whether it is traditional power plants or renewable energy sites (such as wind farms or solar power plants), PQMII-T20-C-A helps maintain grid stability. It monitors the power output of the generator to ensure that the voltage, frequency, and harmonic levels are within an acceptable range for grid interconnection. In wind farms, it can detect power fluctuations caused by gusts and trigger control actions to regulate power output, ensuring smooth integration with the grid.
Healthcare facilities: Hospitals heavily rely on uninterrupted power supply to support life support systems, diagnostic equipment, and IT infrastructure. PQMII-T20-C-A can be used to monitor the power quality of critical areas such as intensive care units (ICUs) and operating rooms. By detecting any electrical abnormalities, it can prevent interference with sensitive medical equipment and ensure patient safety.
