Winding resistance measurements are taken to assess the condition of the windings and identify any faults. We rigorously test ancillary protection systems including Buchholz relays, Pressure Relief Devices (PRD), Winding Temperature Indicators (WTI), and Oil Temperature Indicators (OTI).

Sweep Frequency Response Analysis (SFRA) is carried out to detect any mechanical displacement or deformation within the transformer. Oil quality is meticulously analyzed through breakdown voltage tests and Dissolved Gas Analysis (DGA) conducted by certified laboratories. On-load tap-changers (OLTC) undergo functional checks to ensure their reliability, and bushing tan delta tests are conducted to assess the condition of the bushing insulation.
Each of these tests plays a crucial role in certifying the operational readiness and safety of transformers.

Shunt Reactor Testing:
Our services encompass a wide range of specialized tests for Shunt Reactors, essential components in power systems for voltage control and stability. We conduct Tan Delta tests on bushings to evaluate the insulation condition, crucial for preventing insulation failures. Winding resistance measurements are performed to assess the health of the reactor windings, ensuring they are free from defects and deterioration. Sweep Frequency Response Analysis (SFRA) is carried out to detect any mechanical displacements or deformations within the reactor, which are vital for maintaining its operational integrity. Oil Breakdown Voltage (BDV) tests are conducted to check the dielectric strength of the insulating oil, a key factor in the overall insulation system of the reactor. Functional checks of the (MK Panel) are undertaken to verify the operational readiness and reliability of this control system. Additionally, we test Current Transformers (CTs) associated with the shunt reactor to ensure their accuracy and proper functioning. This comprehensive testing regime guarantees the optimal performance and reliability of shunt reactors in the power network.

Capacitor Bank Testing:
Our capacitor bank testing services encompass a comprehensive suite of evaluations to ensure optimal performance and safety. We begin with a thorough Visual Inspection to identify any apparent issues such as signs of overheating, bulging, or damage. The Tan Delta test is performed to assess the condition of the insulation and detect any deterioration. Insulation Resistance (IR) Testing is another critical component, helping to identify leaks or weaknesses in insulation.
Thermal Imaging is employed to detect hot spots or uneven temperature distribution across the bank, which can indicate potential problems like overloading or connection issues. A detailed Physical Inspection is conducted to check for any signs of corrosion, physical damage, or oil leaks in oil-filled capacitors. Finally, Mechanical Checks are performed to ensure that all connections are secure and the structural integrity of the mounting arrangements is maintained. Each of these tests plays a vital role in ensuring that the capacitor bank functions efficiently, safely, and reliably within the power system.
