App Description
Transformer DGA Calculator Duval's triangle
The "Transformer DGA Calculator" is an Android application designed to calculate and interpret dissolved gas analysis (DGA) values for power transformers. It utilizes Duval's Triangle method to analyze the concentrations of different gases dissolved in the transformer oil and provides insights into the transformer's condition and potential faults.
The main features of the application include:
1. Gas Concentration Input: The user can enter the concentration values of four gases commonly monitored in transformer DGA: Hydrogen (H2), Methane (CH4), Ethylene (C2H4), and Acetylene (C2H2). These concentrations are typically measured in percentage (%).
2. DGA Calculation: Based on the input gas concentrations, the application calculates the DGA value, which is the sum of all gas concentrations. The DGA value is an important indicator of the transformer's condition and potential faults.
3. Interpretation of Results: The application provides an interpretation of the calculated DGA value. It categorizes the DGA value into different levels, such as Normal, Warning, Alarm, or Critical, indicating the severity of the detected fault. This interpretation helps users understand the transformer's health and make informed decisions.
4. Fault Type Determination: The application utilizes Duval's Triangle, which compares the ratios of hydrogen/methane (H2/CH4) and ethylene/acetylene (C2H4/C2H2), to determine the type of fault present in the transformer. The fault types can include Thermal Fault, Partial Discharge Fault, Local Overheating, Arcing Fault, or Unknown.
5. Reset and Share Functionality: The application allows the user to reset all the input fields for gas concentrations and start a new calculation. Additionally, it provides an option to share the application with others via different communication channels.
Overall, the "Transformer DGA Calculator" provides a convenient tool for power transformer operators, maintenance personnel, and professionals in the electrical industry to assess the condition of transformers based on DGA values and make informed decisions regarding maintenance and fault prevention.
