Diagnostic testing of 200 MVA Transformer in a 400 kV Switchyard


The crucial concern of power/process plant managements, the world over, is the cost of reliable operation of plants. Setting up of new plants is prohibitively expensive due to stringent environmental and safety concerns, uncertainties of financial return and extended lead times for new plants. The factors cited above have driven the managements to undertake technical assessment of their plant and equipment to prolong their operation. Operation of plants and equipment till the end of their useful, rather than design life, is the ‘Mantra’ being adopted.

Condition Monitoring and Residual Life Assessment are the modern scientific tools which provide accurate condition of Power / Process plant equipment and components.

On-line condition monitoring of lightning arrester
Transformer Assembly Inspection


The major equipment that need to be monitored on continuous basis in a power / process plant are Generator, Turbine and its auxiliaries, Boiler and its auxiliaries, Transformers, Switchgear, Pumps, Fans, Cables, Motors, Lightning Arresters etc.


ERDA’s expertise in this important activity centers around its qualified and experienced technical and scientific manpower and laboratory facilities such as Materials Testing, High Voltage and Low Voltage Electrical Equipment Testing, Energy Management, Power Electronics etc. The major techniques employed include In-situ Metallography (Replica Test), In-situ Hardness, Fibroscopy, Boroscopy, NDT (including UT, MPT & DPT), Steam Side Oxide Scale Measurements, Videoscopy; In-situ Chemical Analysis, Thermography, Eddy Current Testing, Vibration –, Noise - & Sound - Intensity Analyses/ Measurements, SPM Analysis Thermography, Partial Discharge Measurement on Transformers and CTs by Acoustic Emission Method, C & Tan Delta Measurement using C & Tan Delta Bridge, Partial Discharge Measurement on Rotating Machines by PD Detector, Frequency Response Analysis for Transformers, etc.

ERDA has been recognized by the Central Boilers Board as “Well Known Remnant Life Assessment Organization” under Indian Boiler Act, 1950. The recognition authorizes ERDA to undertake independent NDT & RLA of Industrial boilers, all over the country.


ERDA is providing Condition Monitoring and Residual Life Assessment services to State Electricity Boards, Private Sector Utilities, NTPC, Process Industries as well as various OEMs.


Failure analysis is an interdisciplinary activity involving specialists drawn from the electrical. mechanical and materials science disciplines. ERDA has developed extensive expertise in conducting failure analysis of equipment / components of power and petrochemical plants, the metal processing industry as well as heavy and light equipment manufacturing industry, in general.

In-situ Metallography of Main Steam Pipe


The evaluation tools deployed for failure analysis are, Fractography, Metallography, Chemical Analysis, Corrosion / Erosion Product Analysis, Mechanical Testing, In-situ Metallography, Non-Destructive Testing, FEM, Stress Analysis, etc.


A typical listing of components / equipment on which failure analysis has been conducted by ERDA includes the following:

· Boiler tubes
Turbine blades
Shafts of rotating and reciprocating machinery
Conductors & transmission hardware
Cable / cable joints

Electrical and Thermal Energy Conservation assumes great importance in the context of depleting fossil fuel energy resources, growing Industrial, Agricultural and Domestic demands, losses in Transmission and Distribution Systems and huge financial investments and time factor in building generating facilities. It is estimated that upto 30% of Energy Consumed in productive sectors such as Industry, Agriculture, Power, Transportation etc., can be saved by adopting better equipment maintenance, operational practices and adoption of new energy efficient technologies with very little investments.


With the above background, ERDA set up the Energy Management Section and started providing Energy Audit Services in the Electrical and Thermal areas. Our services have been availed by a large number of Industries in sectors such as power generation (Thermal, Hydro and Nuclear Plants), Iron & Steel, Fertilizers, Chemicals, Petrochemicals, Food Processing Industries etc. Besides these, Municipal Corporations and large Hospitals are also availing our services. ERDA has completed over two hundred thirty Energy Audit assignments to date and the savings in Energy Costs experienced by our clients are of considerable value. ERDA’s strength lies in its multidisciplinary nature, as we have specialists and facilities to meet the clients needs.


ERDA has won ‘Best Improvement in Performance’ and ‘Best Energy Auditor’ Awards of Petroleum Conservation Research Association (PCRA) continuously in a row for three years. ERDA has also won awards from Maharashtra Energy Development Agency (MEDA) for two consecutive years.

Need for EMI/EMC Test :

Ever increasing use of power electronics equipments and communication equipments in every walk of life is increasing the electromagnetic pollution day by day. This pollution may degrade the performance of electronic and electrical equipments. Therefore it is necessary that all electronic equipments or systems must be constructed so as to ensure that any electromagnetic disturbance it generates allows radio and telecommunication equipment and other apparatus to operate as intended, further equipment must be constructed with an inherent level of immunity to externally generated electromagnetic disturbances.
Testing & evaluation has thus become necessary to ensure that the products work satisfactorily in the present day electromagnetic environment. It is essential that each equipment or system design meets the compatibility levels specified in the National / International Standards.
