CT/PT Analysis

CT (Current Transformer) and PT (Voltage Transformer) analysis is very important in Bangladesh, as they play a vital role in ensuring the proper functioning of the power transmission and distribution system. CT and PT analysis is used to verify the accuracy, safety, and stability of the power system. These tests are generally used to evaluate the voltage and current ratings, accuracy, and efficiency of transformers. Various power service providers in Bangladesh such as PDB and private power companies carry out such analysis regularly, so that the safety and stability of the electrical system is maintained and any kind of fault can be identified quickly. This is helpful in ensuring the safe and efficient operation of the power transmission system.
