Transformers Oil Testing (NABL Accredited) Services

Our Transformer Oil Testing Services are conducted with utmost precision and adherence to industry standards, ensuring the safety and longevity of your transformers. Accredited by NABL, we offer comprehensive testing to evaluate the physical, chemical, and electrical properties of transformer oil, as well as insights into the internal condition of the transformer. Our testing services help detect potential issues early and prevent transformer failures.

Physical Parameters

Appearance
- Inspection of oil clarity and color to detect contamination or degradation.
Interfacial Tension
- Measures the tension between oil and water, providing insight into oil quality.
Flash Point
- Tests the temperature at which the oil vaporizes and can ignite.
Pour Point
- Determines the lowest temperature at which oil remains fluid, indicating low-temperature performance.
Density
- Measurement of oil density to assess purity and consistency.
Kinematic Viscosity
- Measures the oil’s resistance to flow at different temperatures, indicating its ability to lubricate and insulate.

Chemical Parameters

Water Content
- Detects moisture levels in the oil, which can cause insulation breakdown.
Total Acid Number / Neutralization Value
- Measures the acid content in the oil, helping assess the degree of degradation.
Sediments and Sludge

Identifies impurities, such as solid particles or sludge, that can harm transformer components.

Electrical Parameters

Breakdown Voltage / Dielectric Strength
- Evaluates the oil’s ability to withstand electrical stress without breaking down.
Specific Resistance / Resistivity
- Measures the resistance to electrical flow, indicating insulation integrity.
Dielectric Dissipation Factor / Tan Delta

Assesses the oil’s ability to insulate by measuring energy loss in the system.

Transformer Internal Condition

Dissolved Gas Analysis (DGA)
- Identifies the presence of dissolved gases in the oil, which can indicate fault conditions such as arcing or overheating.

Transformer Insulating Paper Condition

Furanic Compound Analysis (Furans)
- Detects furans, which are byproducts of paper insulation degradation, helping assess transformer health.

Other Special Tests

Customized testing as per customer requirements for unique transformer conditions and specifications.

Testing Packages as per Industry Standards

Our oil testing services are aligned with the following standards:

IS (Indian Standards)
IEC (International Electrotechnical Commission)
ASTM (American Society for Testing and Materials)

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.
