How to handle the testing report of the sample? What are the scope and standards of testing? Today, the editor of Baijian Testing will take you to understand the specific tests required for the relevant testing business. At the same time, Baijian can also design testing plans based on corresponding testing standards or according to your needs

Testing process

1. Sending samples

2. Checking requirements

3. Targeted quotation

4. Both parties confirm, sign a contract, and start the experiment

5. Completing the experiment: The testing cycle (can be expedited) may change according to the sample and its testing items/methods, and engineers can be consulted

6. Issuing the testing report and providing post service.

Testing items:

Partial parameters, all parameters, insulation special test, insulation type test, transportation quality measurement, sound level measurement for each cooling method, measurement of fan and oil pump motor power, measurement of short-circuit impedance and load loss, mechanical test or evaluation of oil tank transportation adaptability, pressure sealing test of inflatable transformer oil tank, insulation liquid test, measurement of winding hot spot temperature rise, measurement of winding to ground and DC insulation resistance between windings.

, Pressure sealing test for liquid immersed transformers, ratio and polarity test for internal current transformers, external coating inspection, frequency response measurement, insulation inspection for iron cores and clamps of liquid immersed transformers, on-site vacuum sealing test for liquid immersed transformers, insulation routine test, winding resistance measurement, no-load loss and no-load current measurement, dissolved gas measurement in insulation liquid, short-circuit withstand capacity test, temperature rise test, voltage ratio measurement and connection group label verification, Measurement of transient voltage transmission characteristics, vacuum deformation test of liquid immersed transformer, on load tap changer test, pressure deformation test of liquid immersed transformer, measurement of no-load loss and no-load current at 90% and 110% rated voltage, measured value of insulation resistance, marking, lifting, packaging, transportation and storage

Testing standards:

1. Technical parameters and requirements for single-phase oil immersed distribution transformers JB/T 10317-2014

2 JB/T 10317-2014 Technical parameters and requirements for single-phase oil immersed distribution transformers JB/T 10317-2014

100% inspection process:

1. Telephone communication and confirmation of requirements 2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is required
