Indian Customer Visits Wrindu for Testing Equipment Demo
Wrindu recently welcomed a customer from India for a company visit, product review, and technical exchange. The visit focused on the customer's experience with Wrindu testing instruments, an introduction to the company's high-voltage testing equipment and transformer testing solutions, and a hands-on demonstration of the RDPDZ-104T Partial Discharge Tester.
Throughout the visit, Wrindu's sales and technical teams worked together to answer questions, explain product applications, and provide practical guidance. Through face-to-face discussions, showroom demonstrations, and a live video connection with the factory team, the customer gained a better understanding of Wrindu's products and technical support capabilities.
Morning Meeting: Customer Feedback on Wrindu Testing Equipment

The morning began with a meeting in the conference room, where the customer shared feedback on two Wrindu instruments previously used in practical testing: the RD6000A Tan Delta Tester and the RDHG-E CT and PT Analyzer.

The discussion covered the customer's experience with the equipment, its practical applications, and technical questions encountered during use. Wrindu's sales and technical teams listened carefully and provided explanations based on the customer's requirements.
The RD6000A is designed to measure insulation dielectric loss and capacitance, helping technicians assess the insulation condition of electrical equipment. The RDHG-E supports CT and PT testing, helping users evaluate instrument transformer characteristics for power system measurement and protection applications.

For more information, visit the Transformer Tan Delta Tester product page to learn about insulation dielectric loss testing, or explore the Variable Frequency Transformer Comprehensive Characteristic Tester for CT and PT testing applications.
This direct exchange helped Wrindu better understand the customer's testing experience while providing an opportunity to address questions and discuss practical requirements.
Exploring Wrindu's High-Voltage Withstand Voltage Testing Equipment





After the morning meeting, the customer visited the Wrindu showroom to explore more products and learn about the company's electrical testing solutions.
One important area of the product introduction was high-voltage withstand voltage testing equipment. These instruments are used to evaluate electrical insulation under specified test conditions and support testing and maintenance work involving power equipment, cables, and other electrical installations.
Different applications require different testing methods. Depending on the test object and applicable procedures, engineers may select AC withstand voltage testers, DC high-voltage testers, or very low frequency (VLF) withstand voltage testing equipment.
Wrindu offers a range of High Voltage Insulation Testing Equipment for different electrical testing requirements. This product category provides customers with options for insulation testing across a variety of field and laboratory applications.
During the showroom tour, Wrindu's sales and technical teams explained product functions, discussed typical applications, and answered the customer's questions. The team also helped the customer understand how different types of testing equipment can support inspection, commissioning, and maintenance tasks.
Transformer Testing Equipment for Inspection and Maintenance
Transformer testing was another important part of the showroom visit. Regular electrical testing helps maintenance teams evaluate transformer insulation, verify electrical characteristics, and identify potential problems before they affect equipment operation.
Wrindu provides a range of Transformer Test Equipment for different testing requirements. Depending on the selected instrument, these solutions can support insulation testing, dielectric loss measurement, winding resistance measurement, turns ratio testing, and other electrical diagnostic tasks.
For example, a transformer tan delta tester measures dielectric loss and capacitance to help assess insulation condition. CT and PT analyzers evaluate instrument transformer characteristics, including ratio, polarity, and excitation performance. Selecting the appropriate instrument depends on the equipment under test, the required parameters, and the applicable test procedure.
By introducing these product categories and explaining their applications, the Wrindu team helped the customer explore additional solutions beyond the instruments already in use.
Afternoon Demonstration: RDPDZ-104T Partial Discharge Tester


In the afternoon, the customer wanted to learn more about the connection methods of the RDPDZ-104T Partial Discharge Tester and how to use its different sensors.
To provide practical guidance, Wrindu arranged a hands-on demonstration using the actual instrument. The team also established a live video connection with employees at the Wrindu factory, allowing the customer to follow the testing process and communicate directly with the technical team.
During the demonstration, the team explained the equipment setup, discussed sensor connections and applications, and reviewed the resulting test reports and measurement data. This practical approach helped the customer better understand the testing workflow and clarify questions that can be difficult to resolve through written instructions alone.
Partial discharge detection methods and sensor selection depend on the equipment being tested and the intended application. Different sensors may be used for detecting discharge activity in equipment such as switchgear, transformers, and other high-voltage installations. Correct connections and suitable sensor selection are important for obtaining useful measurement data.
To learn more about this type of testing solution, visit Wrindu's Comprehensive Partial Discharge Inspection Instrument product page.
The live demonstration also showed how Wrindu combines practical product training with communication between its on-site team and factory personnel. By observing the equipment setup and reviewing the test results, the customer gained a clearer understanding of the instrument's operation.
Customer Recognition of Wrindu's Service and After-Sales Support
Throughout the visit, Wrindu's sales and technical teams worked closely together to address the customer's questions. The team provided product explanations, discussed testing applications, and arranged the practical demonstration according to the customer's technical needs.
The customer expressed satisfaction with Wrindu's service and after-sales support, noting that the support provided throughout the cooperation had been very good. The customer also expressed a willingness to continue working with Wrindu.
For electrical testing equipment, customer support does not end with delivery. Users may need assistance with instrument operation, connection methods, sensor selection, test procedures, and measurement results. Responsive technical communication helps customers understand their equipment and use it more effectively.
Wrindu aims to support customers through product introductions, technical consultation, practical demonstrations, and after-sales assistance. The company's sales and technical teams work together to respond to customer questions and help identify suitable testing solutions for different applications.
Wrindu Looks Forward to Continued Cooperation
The visit provided an opportunity for both parties to review previous product experience, explore additional high-voltage and transformer testing solutions, and discuss technical questions through practical demonstrations.
Wrindu appreciates the customer's feedback and continued trust. The company looks forward to strengthening its cooperation with customers in India and other international markets by providing electrical testing equipment, technical guidance, and ongoing after-sales support.
Whether you need high-voltage withstand voltage testing equipment, transformer testing instruments, or partial discharge detection solutions, Wrindu can help you explore options for your application.
