Online monitoring device for power quality

Product Introduction

GHPQ531Online monitoring device for power qualityIt is a newly developed power quality monitoring device by our company, which can simultaneously meet the monitoring of multiple voltage and current segments. It can achieve real-time monitoring and recording of parameters such as power grid harmonics, power grid voltage deviation, power grid frequency deviation, voltage fluctuations and flicker, three-phase voltage imbalance, three-phase current imbalance, temporary overvoltage and transient overvoltage, and harmonics between public power grids.

Features

Component measurement and voltage imbalance analysis
The GHPQ531 series power quality online monitoring device can measure the imbalance of voltage and current, as well as the amplitude and phase of zero sequence, positive sequence, and negative sequence, and display the phase diagram of voltage and current. The series of power system frequency fluctuation monitoring and recording devices for online monitoring of power quality have a frequency measurement accuracy of 0.001Hz, with a frequency range continuously from 42.5Hz to 57.5Hz. They monitor the frequency of the power system online, and can promptly alarm and record if the frequency exceeds the limit.

harmonic analysis
Monitor the 63rd harmonic component of the tested signal, including 1-50 harmonics, harmonic distortion rate, total harmonic distortion rate, harmonic phase angle, and interharmonics, to meet the testing requirements of GB/T14549 and IEC61000-4-7 for harmonics in public power grids.

Measurement of excessive power quality
The GHPQ531 series of online monitoring devices for power quality can continuously monitor whether the power quality meets relevant standards. Through software, different exceeding conditions can be set, and the corresponding exceeding quantity can be recorded by starting the statistics of exceeding power parameters. The time resolution is up to 1ms.

Flicker analysis
The flicker effect caused by rapid voltage changes in public power supply points due to impact power loads (such as steelmaking arc furnaces, arc welding machines, etc.) can easily lead to eye fatigue, discomfort, and even emotional distress. The GHPQ531 series power quality online monitoring device has voltage flicker monitoring function and complies with the GB/T12326-2008 standard.

Voltage fluctuations and fault recording
The series of online monitoring devices for power quality can capture the waveforms of all voltage and current channels and analyze interference sources. Harmonic components exceeding the standard, distortion rate exceeding the standard, voltage effective value exceeding the standard, short circuit faults, etc. can all initiate voltage waveform and fault recording to capture subtle changes in voltage waveform.

IEC61850 communication protocol
Implementing remote control and parameter management of terminals through IEC61850; The reporting mechanism uploads terminal data in real-time according to scheduled and summoning methods

Interoperability: Ensure that products from various manufacturers that comply with the IEC61850 standard can easily achieve interoperability

Long term stability: Abstract Communication Services (ACSI) are used to define specific communication protocol stacks through Specific Communication Service Mapping (SCSM), adapting to changes and developments in communication technology.
