The Erection & Commissioning Service is conceptually used in the installation process of several industrial plants. We are backed by a team of adroit personnel who render these services in the most efficient way within the postulated time frame. Also, these services are greatly appreciated by our patrons for their nimbleness. We offer ETC services for Transformer/Reactor/CT/PT/CVT having various ratings. We have rich domain expertise and dedicated manpower for the erection of small to higher rating Transformers. We follow all the safety standards with the consent of the customer to avoid any minor or major incidents. After the completion of ETC work, a certificate will be provided ensuring the installations are done perfectly.

Testing is extremely essential for preventive as well as breakdown maintenance. Excellent Diagnostic and Research Agency has a dedicated testing team furnished with advanced instruments, which conducts tests with accuracy, reliability, and repeatability. The teams are well trained and equipped to thoroughly and reliably test all kinds of installations in a switchyard and transmission lines.

The Entire Process

Pre-erection activities are completed before starting erection

Erection of built-in parts of the plant

Erection of the main operating components

Erection is similar to installation however erection is to install something piece by piece that rises up.
Commissioning is bringing the installed thing into running as per the required professional standards.
Testing means to confirm the installed device is running with complete functionality and it is delivering the required output.

Pre-erection activities

Preparation of a plan for the implementation of erection work and sequence of various activities
Site storage planning consists of open, locked, semi-closed storage and road construction, connection for plant distribution to assembly field.
Erection of temporary structures, living quarters needed to work smoothly and quickly on the site.
Building power, water, compressed air system for erection operations. DG sets of sufficient capacity to be retained when a power failure occurs.
Arrangement of lighting of erection site and nearby area.
Ensure the timely supply of equipment and materials needed for the continuation of erection work in conjunction with charts and schedules.
Providing installation plans for hoisting, carrying systems, instruments, and equipment as well as coordinating the transfer of material to the site. The content will be removed and transferred to a pre-identified position in the unloading port.
Arrangement of protective measures to protect workers and machinery during the storage, transport, and deployment of various plant components.

Erection of main operating components

In the first point, a well-coordinated overall plan is planned for the development of civil works and activities related to the building of hydro-mechanical and hydro-generating systems.
A PERT / CPM shall be established to track current operations and sensitive activities in order to prevent any interruption in the plan.
The number of building works to be finished by months in keeping with the project’s total planned construction timetable.
Big activity-wise PERTs are established displaying sequence and length of activities matching delivery schedule and civil building activities to track erection works in charge. This should provide a timeline and length as per the total timetable of all essential and concurrent tasks to complete the erection work.

Transformer Oil Filtration Services

Transformers are critical to electrical systems, and oil quality plays a significant role in their performance and longevity. Nearly 75% of transformer failures are due to contaminated and deteriorated oil, which can be caused by the development of aging products inside high-voltage equipment. These contaminants can drastically affect transformer efficiency, insulation strength, and overall health. Regular oil filtration is therefore essential to maintain optimal transformer performance.

Common Contaminants Affecting Transformer Oil

Transformer oil is prone to absorbing harmful contaminants, including:

Formation of Acids due to chemical decomposition.
Oxidation of oil.
Gas Formation due to electrical and thermal stresses.
Moisture which degrades insulating properties.
Solid Contaminants such as dust, fibers, metallic particles, varnish, and sludge.
Physical Contamination from leakage in the transformer enclosure.

Consequences of Ignoring Oil Filtration

Failure to regularly filter transformer oil can lead to serious operational issues, including:

Arcing in transformer components.
Overheating, reducing electrical efficiency and transformer life.
Corona Discharges, causing insulation breakdown.
Decreased Insulating Strength of the transformer oil, compromising performance.

Our Transformer Oil Filtration Process

At Core Power, we use our specially designed Ultra-High Vacuum Oil Filtration Machine to effectively filter transformer oil. The filtration is conducted using proper procedures in compliance with IS-6034-1989 and IS-1866-2000 standards, ensuring optimal performance and safety. Our skilled team ensures each step is carefully followed for precise results.

What You Get After Oil Filtration

Here’s a comparison of key oil parameters before and after filtration:

No.	Parameters	Before Oil Filtration	After Oil Filtration
1	Breakdown Voltage (BDV)	Below 30KV	Above 80KV
2	Moisture Content	50 ppm	3 ppm
3	Gas Content by Volume	10%	0.1%
4	Suspended Particles	Infinite	Less than 1 Micron

Benefits of Regular Oil Filtration

Improved Efficiency: Cleaner oil means better transformer performance and minimized energy loss.
Extended Lifespan: Regular filtration prevents premature aging of the transformer and reduces the risk of failures.
Cost Savings: Helps to avoid costly maintenance and breakdowns, lowering overall expenses.
Enhanced Reliability: Ensures your transformer operates consistently under various conditions.
Environmental Protection: Proper filtration helps reduce the environmental impact by preventing contamination of oil.
