Table of Content

Currently, there are many products and solutions for online monitoring of transformer status. But to find a product that meets the market demand for efficiency and simplicity is not an easy thing. Therefore, S5T and Camlin Energy have combined and provided a TOTUS transformer monitoring solution in Vietnam. Through the installation and deployment, the success level of the product application has been shown in projects.

Transformer monitoring solution of TOTUS – Camlin Energy

Camlin’s transformer monitoring system includes the following monitoring technologies:
Monitoring of gas content in oil (DGA) using PhotoAcoustic effect (PAS)
Using photoacoustic analysis technology to detect gases in oil, this method can detect 9 types of gas dissolved in oil including oxygen.
Monitoring of gas content in oil (DGA) using NDIR . technology
Using an infrared (non-dispersive) absorption sensor, the gas type and concentration can be detected by the infrared absorption spectrum of the gas and the corresponding absorption amount. This technology is commonly used to analyze 5 different gases.
Online partial discharge (PD) monitoring using Camlin triangulation and Tap adapter (Bushing Adapter) sensor
Tap adapters are designed to ensure safe and reliable installation with surge protection and effective noise reduction. Tap adapter continuously monitors to ensure all PD signals are detected. The data is then converted into a graphical form (PD Triangle) making it easy to recognize and distinguish the noise signal.
Monitoring of arcing through comparison of DGA and PD
Bushing monitoring includes monitoring for short circuit, dirt, dielectric loss (tan delta), arcing (Arcing):
Bushing monitoring uses a smart algorithm to eliminate false alarms, help detect errors that are forming early, and automatically separate the PD signal in the bushing. The solution for measuring the relationship between tan delta and bushing capacitance has high stability, is also easy to put into operation, does not need to be adjusted, does not need to be equipped with additional software.
Fault Current Monitoring (TFC)
Fault current monitoring records all fault currents through the transformer windings and evaluates key parameters to predict transformer winding strain. In addition, it can also evaluate the correlation between fault current with DGA, PD, Bushing measurement data.
Camlin Energy’s transformer online monitoring solution includes the combination and calculation of bushing (Bushing), partial discharge (PD) and dissolved gas (DGA) monitoring. ) to make an overall conclusion about the condition of the transformer.
