Quality & testing

Every unit is routine-tested before it leaves the floor.

At Aditya Energy, quality is at the core of everything we do. We believe that dependable transformer performance begins with sound engineering, precision manufacturing, stringent quality control, and a commitment to continuous improvement.

Quality assurance & quality commitment

Engineered for Excellence. Driven by Quality.

As an ISO 9001:2015 certified organisation, we follow a structured Quality Management System (QMS) to maintain consistency, process discipline, and customer satisfaction across our manufacturing operations.

From design and engineering to raw material procurement, manufacturing, inspection, and final testing, every stage is monitored through defined quality procedures and inspection protocols to ensure that our transformers meet applicable national and international standards, along with customer-specific requirements.

Quality principles

Our Quality Philosophy

Our quality philosophy is built around five key principles.

Engineering Excellence

Ensuring technically sound designs with careful consideration of electrical, thermal, mechanical, and operational requirements.

Quality Raw Materials

Procuring materials and components from qualified suppliers and conducting appropriate incoming inspections to ensure conformity with specified requirements.

Controlled Manufacturing

Maintaining defined manufacturing procedures, process controls, and inspection checkpoints to ensure precision, consistency, and workmanship.

Rigorous Testing & Inspection

Conducting applicable routine tests and quality inspections to verify product performance, safety, and compliance before dispatch.

Continuous Improvement

Strengthening our quality management processes through internal audits, corrective actions, employee involvement, and customer feedback.

ISO 9001:2015 certified

Quality Management System

Our Quality Management System is certified to ISO 9001:2015, demonstrating our commitment to systematic quality management, operational consistency, risk-based thinking, and continual improvement.

We focus on maintaining effective quality controls throughout the manufacturing lifecycle, ensuring that every product is manufactured and inspected in accordance with approved specifications and applicable standards.

Before dispatch

Testing & Inspection

Every transformer undergoes applicable inspection and testing procedures to verify its electrical characteristics, performance parameters, and workmanship before final dispatch.

Our testing and inspection activities include:

Winding Resistance Measurement
Voltage Ratio and Vector Group Verification
No-Load Loss and No-Load Current Measurement
Load Loss and Impedance Voltage Measurement
Applied Voltage Withstand Test
Induced Voltage Withstand Test
Insulation Resistance Measurement
Transformer Oil Testing, wherever applicable
Dimensional and Visual Inspection
Functional Checks of Accessories and Protection Devices

All applicable tests are performed in accordance with relevant IS/IEC standards and approved customer specifications.

What we stand by

Our Quality Commitment

At Aditya Energy, quality is not merely a final inspection process; it is an integral part of our engineering and manufacturing culture.

We are committed to:

Delivering consistent product quality and reliable performance.
Maintaining compliance with applicable standards and specifications.
Strengthening manufacturing processes and quality controls.
Ensuring customer satisfaction through dependable products and services.
Continuously improving our people, processes, and capabilities.

At Aditya Energy, every transformer reflects our commitment to engineering excellence, manufacturing precision, and long-term operational reliability.

Our promise

Quality is our promise. Reliability is our standard.

Aditya Energy

Quality assurance

How we hold the standard.

Reliability of design, a zero-failure aim, and strict adherence to laid-down quality-system standards, applied at every stage rather than checked at the end.

Design review

Magnetic circuit, windings, insulation, losses, impedance and short-circuit forces calculated to IS 2026 and IEC 60076 before any material is cut.

Incoming material check

CRGO laminations, conductor and insulating material inspected on arrival. A transformer is only as good as what goes into it.

In-process inspection

Coil clamping, core-coil assembly, tanking and brazing checked stage by stage on our own floor, not signed off at the end.

Oil filtration

Filtered through our 4.5 KL mobile plant to the required breakdown voltage before and after tanking.

Routine and type testing

Every unit routine-tested to IS 2026 in our own 66 kV bay. Type tests performed on request.

Documented and traceable

Each unit ships with its routine test certificate, GA drawing and rating plate details: the paperwork an inspector asks for.

In-house testing

The test bay, and what it proves.

Testing in-house is the difference between a delivery date we control and one we hope for. These are the facilities on our Vadodara floor.

Equipment / test	Range	Standard	What it proves
High-voltage test bay	up to 66 kV	IS 2026	Routine and type testing of oil-immersed transformers on our own floor.
Ratio, polarity and vector group test	All ratings	IS 2026	Confirms the unit is wound and connected exactly to the approved design.
Winding resistance measurement	All ratings	IS 2026	Detects a poor joint or a wrong turn count before the unit is tanked.
No-load and load loss measurement	up to 25000 KVA	IS 2026	The losses a buyer is contractually paying for, measured rather than quoted.
Insulation resistance and HV withstand	up to 66 kV	IS 2026	Proves the insulation system holds at the specified voltage class.
Mobile oil filtration plant	4.5 KL	IS 1866	Runs on our floor or at your site during installation and commissioning.
Overhead crane	30 tons	–	Handles core-coil assemblies and tanked units without external lifting hire.
Winding machines	to 12 tons	–	Spiral, cross-over, helical and continuous disc windings wound in-house.

A routine test certificate accompanies every unit dispatched. Type test reports and witnessed testing are available on request. Tell us at the enquiry stage so we can schedule the bay.
