Technical Principle
The core working principle of our induction withstand voltage testing equipment is based on electromagnetic induction. The complete implementation logic is as follows:
1. Input: AC power supply (power frequency or variable frequency) is input into the system.
2. Processing: The step-up transformer converts the input voltage into high-voltage induction voltage, which is applied to the transformer winding under test.
3. Output & Result: Real-time monitoring of insulation status is carried out through high-precision sensors; if insulation breakdown occurs, the system automatically alarms and records data.
