Our Transformer Test System is an advanced, industry-leading solution designed to ensure the reliability, performance, and safety of your power transformers. It offers a comprehensive suite of tests to assess the health of your transformers, helping you prevent failures, optimize performance, and extend the lifespan of your equipment.

Application

Our test system, featuring full automation, is the optimal solution for conducting comprehensive routine tests on 10-35KV distribution transformers, in accordance with the IEC60076 standard. It is specifically designed for routine and temperature rise testing of 10-35KV distribution transformers, ensuring their efficient and safe operation.

Main Features

  • Our system allows for manual recording of test data, which is then securely stored in the database. The No-load test data can be automatically corrected based on waveform and rated voltage, while Load test data can be adjusted according to temperature (75℃, 100℃, 120℃, 145℃) and rated current.
  • During the No-load test, the system monitors the Low Voltage (LV) side, and in the Load test, it keeps track of the High Voltage (HV) side current. All test functions and processes can be easily managed via the front panel buttons.
  • The system ensures all test results are corrected in compliance with GB1094, IEC60076, or ANSI C57 standards. The test procedure can be executed using PC software, and all data can be stored and printed for record-keeping and analysis.
  • For safety, the system is equipped with zero protection, over-current protection, and over-voltage protection functions. It also features an automatic CT/PT range switch. The test bench fully controls the entire loop circuit and monitors the measurements, ensuring accurate results and safe operation. The system is also equipped with a safety alarm system for added security.
