Insulation health diagnosis using IR Tester

With an increase in demand for electrical energy day by day, electrical installations, structures and systems are also increasing. It is very important to maintain these systems and equipment safely and efficiently. These requirements of the electrical system are fulfilled by the insulating material. The property of insulating material to oppose the flow of current …

Monitoring the Internal health of Transformer using Dissolve Gas Analyser

In our earlier blog on the transformer, we shared our views on how to detect possible core & winding damage using the Transformer Turns Ratio Meter. The oil which acts as the insulating medium is one of the reasons for internal transformer failure. The oil decomposes mainly due to Thermal, electrical & chemical stress due …

Evaluation of possible Winding & Core damage through Transformer Turns Ratio Measurement (TTRM)

In a previous blog post, we shared our views on the importance of transformer testing and discussed: a) the principles of winding resistance measurement, b) OLTC condition analysis and c) our thoughts on the ideal kit for transformer testing. In this blog post, we will share our knowledge on assessment of possible winding & core …

New Market Story: An Energy Management System For Telecom Corporate Park

Over the last twenty years, the telecommunications sector in India has undergone a major revolution. Today, India is the worldโ€™s second-largest telecommunications market with a subscriber base of 1.16 billion (Source: India Brand Equity Foundation). Over the next five years, rise in mobile phone penetration and decline in data costs is expected to add 500 …

Transformer Winding Resistance Measurement, OLTC Condition Analysis and Ideal Kit Specifications

Power transformers are one of the most expensive and critical assets of the power sector. In this blog, we will discuss [1] principles of winding resistance measurement, a common transformer test prescribed in various standards such as IEEE C57.12.90-2006 Clause 5, IEC 60076-1 Clause 10.2, IS 2026-1 Clause 10.2; [2] OLTC condition analysis; and [3] …

Success Story: Testing and Maintenance of Electrical Equipment at a Steel Manufacturing Plant

Studies show that in 2019, India was the worldโ€™s second largest producer of crude steel with a capacity of 111.2 MT. Indiaโ€™s finished steel consumption is also projected to rise from 99 MT (2018-19) to 230 MT by 2030-31. Furthermore, with the governmentโ€™s view towards self-reliance, steel companies are ramping up steel production capacity. Therefore, …

Success Story: Enhancing the Life Span of 500 MVA ICT through Controlled Switching Devices

In the last two blogs, we have shared our knowledge on the technique of controlled switching to enhance the life expectancy of assets in the electrical network and improve system stability. By discussing how life span of reactors, capacitor bank assets and power transformers can be enhanced through controlled switching, we have underscored the criticality …

Partial Discharge Testing: Need, Testing Methodologies and Addressing Defects

Studies show that over 85% of disruptive failures in high voltage (HV) and medium voltage (MV) equipment are Partial Discharge related. Partial Discharge (PD) activity provides evidence  of deterioration in assets, which can propagate and increase, until the insulation is no longer able to withstand the electrical stress therefore leading to flash-over and finally equipment failure. Therefore, early detection …
