Power Quality Monitoring using Transient Analysis in LV Power Distribution Network

Maharashtra State Electricity Distribution Co. Ltd. (Mahavitaran) is one of the largest power distribution companies in India. It has over 6.3 lakhs Distribution Transformers (DTs) with transformation capacity of over 72,500 MVA. Its vision is to be the best power distribution utility in India delivering quality and reliable power at a competitive price.

The key priorities of MSEDCL is to reduce power distribution losses, improve reliability and quality of power supply, and ensure power for all.

In line with this, MSEDCL decided to conduct a pilot project to monitor power quality and reliability of Distribution Transformers under two different substation locations in Mumbai. The pilot project was designed as part a Smart Grid implementation, using an intelligent device with in-built communication module, which relayed real-time parameters to a central monitoring station for processing and analysis. For voltage quality measurements, EN 50160 and IS 17036 – 2018 were used as reference standards
