A high voltage test transformer is important equipment in electrical testing, and special attention should be paid to safety and operation specifications when using it. The following are the main precautions for using high voltage test transformers.
1. Security protection
Wear protective equipment such as insulation gloves and shoes to ensure personal safety.
Obvious warning signs should be set up in the test area, and non-relevant personnel are prohibited from entering.
Ensure that the device is properly grounded to prevent leakage or static electricity accumulation.
2. Check the device
Check the appearance of the transformer before use to ensure that there is no damage, crack, or oil leakage.
Check whether the cable is firmly connected to avoid poor contact or short circuits.
Ensure that the transformer oil level is normal and the oil quality meets the requirements.
3. Operation specifications
Strictly follow the equipment instructions to avoid overload operation.
Gradually increase the pressure to avoid sudden application of high pressure to prevent damage to equipment or samples.
During the test, closely monitor the voltage, current, and other parameters, and power off immediately if any abnormality is found.
4. Environmental requirements
Ensure that the test environment is dry and ventilated, and avoid use in humid or high-temperature conditions.
Keep away from inflammable and explosive materials to prevent fire.
5. Maintenance and maintenance
Check the insulation performance of the transformer regularly and replace aging parts in time.
After the test, clean the equipment and store it properly to avoid moisture or contamination.
Supplementary information
The high voltage test transformer is usually used for the withstand voltage test and partial discharge test. Its output voltage is high, and improper operation may cause equipment damage or personal injury. Therefore, operators need to be professionally trained and strictly abide by relevant procedures.
