When conducting a transformer induction withstand voltage test using a variable frequency series resonance system, it’s crucial to ensure that all non-tested windings are securely short-circuited and properly grounded. This setup prevents any potential suspension of voltage in the test specimen, ensuring the safety and accuracy of the test. Ideally, the test sample should maintain a stable grounding condition throughout the procedure.
During the test, the connection between the inverter resonant system and the transformer casing being tested must follow the specific grounding guidelines provided by our company. This ensures optimal performance and minimizes the risk of electrical interference or damage. Always prioritize proper grounding practices to safeguard both equipment and personnel.
The principle behind the transformer induction withstand voltage test involves evaluating both the main insulation and the longitudinal insulation simultaneously. This test typically applies a voltage that is approximately double the transformer’s rated voltage. To prevent core saturation, the test frequency should exceed twice the rated frequency, usually ranging from 100 to 400 Hz. Industry experience suggests that the ideal test frequency often falls between 150 and 200 Hz, balancing effectiveness with practicality.
In addition to these technical considerations, it’s important to take precautions such as verifying all connections before starting the test, ensuring no foreign objects interfere with the setup, and confirming that all safety measures are in place. These steps help ensure a successful and reliable test outcome.
If you’re unsure about any aspect of the process, don’t hesitate to consult with an expert or refer to detailed user manuals. Safety should always remain your top priority when working with high-voltage equipment.

Pocket Type Nickel Cadmium Battery
The nickel–cadmium battery (NiCd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation NiCd is derived from the chemical symbols of nickel (Ni) and cadmium (Cd).
Pocket Type Nickel Cadmium Battery capacity range is from 10ah to 1200ah, have three series: low discharge rate, medium discharge rate and high discharge rate.
