Diagnosis of Inter-Turn Shorts of Loaded Transformer Under Various Load Currents and Power Factors; Impulse Voltage-Based Frequency Response Approach

Autor: Natarajan Shanmugam, Srinivasan Gopal, Balasubramanian Madanmohan, S. P. Balaji, Rajesh Rajamani

Publikováno v: IEEE Access, Vol 9, Pp 40811-40822 (2021)

Inter-turn short circuits within the transformer winding are diagnosable through the impulse voltage based frequency response analysis (IFRA). If the diagnosis is made Online, interruption to the power network can be avoided. However, the transformer

Influence of the Load on the Impulse Frequency Response Approach Based Diagnosis of Transformer’s Inter-Turn Short-Circuit

Autor: Natarajan Shanmugam, Balasubramanian Madanmohan, Rajesh Rajamani

Publikováno v: IEEE Access, Vol 8, Pp 39454-39463 (2020)

Frequency Response Analysis (FRA) is an Off-line condition monitoring technique for the transformers and is successful, in diagnosing mechanical faults and inter-turn short-circuits. Only limited literature is available for On-line FRA works, and the

Extended Application for the Impulse-Based Frequency Response Analysis: Preliminary Diagnosis of Partial Discharges in Transformer

Autor: Kamalaselvan Arunachalam, Balasubramanian Madanmohan, Rajesh Rajamani

Publikováno v: IEEE Access, Vol 8, Pp 226897-226906 (2020)

Frequency response analysis (FRA) with low impulse voltage signals (IFRA) is useful in diagnosing faults like the mechanical displacements and inter-turn shorts in transformers. However, they fail to diagnose the presence of any source of partial dis

Extended Use for the Frequency Response Analysis: Switching Impulse Voltage Based Preliminary Diagnosis of Potential Sources of Partial Discharges in Transformer

Autor: Kamalaselvan Arunachalam, Balasubramanian Madanmohan, Rajesh Rajamani, Natarajan Prabaharan, Hassan Haes Alhelou, Pierluigi Siano

Publikováno v: Applied Sciences, Vol 10, Iss 22, p 8283 (2020)

The Frequency Response Analysis approach (FRA) is useful in the fault diagnosis of transformers. However, its usefulness in diagnosing any potential sources of Partial Discharge (PD) in transformers has not been thoroughly investigated so far. In thi
