Periodic partial discharge monitoring solution for thermoelectric generators and engines


Periodic partial discharge monitoring solution for thermoelectric generators and engines

PD monitoring and analysis solution for thermoelectric generators and engines that monitor, collect and analyze PD data periodically or at irregular intervals during equipment operation: the product can store data PD pulse over time, creating a basic trend line of PD and when this stable trend is broken, it will give an alert for maintenance and repair.


Table of Content

One of the biggest risks when operating a thermal power plant is uncontrolled partial discharge. At that time, potential problems for the plant can be fire, insulation degradation, grid overload, even equipment shutdown. Therefore, early detection and prevention of damage by PD monitoring solutions are considered as important priorities.

Significance of installing partial discharge monitoring systems for thermoelectric generators and engines

Partial Discharge (PD) monitoring plays a very important role in monitoring the insulation quality of generator and motor stator windings in thermal power plants, in order to record discharge data. by the time. When there is a significant increase in the PD pulse, breaking the trendline that has existed for a long time in operation, these data are used as the basis for maintenance, maintenance and repair according to the condition of the equipment. to reduce costs and maximize the revenue and output of the factory.

Benefits of installing a PD monitoring and analysis solution for thermoelectric generators and engines:

  • Helps to monitor, collect and analyze PD data periodically or at irregular times during equipment operation.
  • Stores PD pulse data over time, creates a basic PD trendline, and when this stable trend is broken, gives an alert for maintenance and repair.
  • Help the factory build a maintenance and repair plan based on the condition of the equipment, reduce costs, optimize working process, maximize output and revenue.

Sensor EMCs – 80 pF


Data Collector TGA-B

+ Software

PD View and IAM software are installed on the computer connected to the measuring device, analyze and report the PD status in the stator winding with high accuracy.

+ Service

The service collects and analyzes PD data periodically with a frequency depending on the actual condition of the thermoelectric generator and the engine being monitored.

Installation process of periodic PD monitoring system TGA-B

Step 1: Survey and determine the locations where EMC sensors and junction boxes need to be installed.

Step 2: Make a construction plan to install the equipment at the surveyed locations.

Step 3: Connect and calibrate the signal, ensuring it is correct according to the company’s noise filtering technology.

Step 4: Get data from the junction box to the TGA-B collection device, connect it to a computer with the company’s specialized software installed to provide PD analysis.

Why should you choose to install Iris Power’s TGA-B periodic PD monitoring system provided by S5T?

Why choose Iris Power’s PD monitoring solution?

During PD monitoring, there are a lot of noise signals coming from many sources, which can be from inside the transmitter, or also from outside the system, so PD analysis becomes very difficult. Therefore, noise separation filtering technology when monitoring and analyzing data about PDs of brands becomes a separate quality and value standard.

For thermoelectric generators and motors, based on the bus duct length, it is possible to choose to use one or a combination of many condenser sensors together, combined with high-tech data acquisition equipment. dedicated to can eliminate most types of interference and retain only the PD signal for machine condition analysis. The characteristic of the PD pulse is that the surge time current pulse is particularly fast and lies mainly in the frequency range of 50 – 250 MHz, while the large and high amplitude disturbances are located in the frequency range below 20 MHz.

Iris Power specializes in researching and applying leading and famous PD Online and Offline monitoring solutions around the world. Applied to a PD monitoring solution, Iris Power designs and manufactures sensors (Epoxy-Mica Capacitors – EMCs) and measuring instruments (TGA-B) that can successfully remove interference from PD pulses efficiently. And especially, users can perform PD test, analyze results quickly after only 2 days of training.
