Multi-frequency Power Supply Unit

1Summary

Voltage TransformerPTInduction withstand tests are a crucial procedure in the power system, ensuring that product quality meets national standards.PTThe inter-turn, inter-layer, inter-section, and phase-to-phase longitudinal insulation induction withstand voltage tests for the windingPTA critical item in insulation testing, the longitudinal insulation test requires applying test voltages through a variable frequency power supply unit to conduct withstand voltage tests.PTConducting inductive withstand tests can help staff identify issues promptly, preventing severe consequences.

Our multi-frequency withstand test equipment, produced with microcomputer control and designed using advanced variable frequency and high-speed sampling technology, offers higher efficiency than traditional three-frequency generators. It boasts stable output voltage, high measurement accuracy, and excellent repeatability. Additionally, it features automatic voltage increase, automatic timing after reaching the set value, and automatic voltage decrease upon completion of timing. Operation is straightforward.Extreme.It's simple. The instrument features a backlit large-screen LCD display.All.Chinese operating interface with real-time clock and mini printer. The instrument features an integrated structure, lightweight, and easy to carry.

Key Features:

Prevent Voltage Surge - Accompanied by a high-impedance capacitor voltage divider, it can directly monitor the high voltage on the primary side and automatically complete the induced withstand voltage test.
