High Frequency Surge Testers

7713 impulse winding tester has 2-channel 10KV that is capable of measuring inductance down to 0.5uH and magnifying high-frequency harmonics to avert shorts through the layers of coiling. Occurrence of mild corona between coils will generate harmonics with high-frequency (>10MHz) and small amplitude, which can not be noticed by a ordinary impulse coiling tester that can only detect gentle amplitude without spotting the flaws. We have deployed HARM (high-frequency harmonics analysis) method to enlarge top-frequency harmonic then to exhibit them on screen then recognize each gentle discharge through layers and assure the standard of every component coil.

Impulse Surge Tester : 2 Channel of 5V.

Surge/Impulse winding tester has a 7703 model which has 2 channel of 5V. It measures inductance over to 0.5uH and magnifies elevated-frequency harmonics to hinder shorts via the layers of windings. Development of lenient corona between twists would produce harmonics with slight amplitude and top-frequency up to 10MHZ that is not detected by conventional testers, which can not detect faults. Our company has installed high-frequency harmonics analysis, ie., HARM process, which boost the influential-frequency harmonics, show them of to the screen, discern every gentle release between the layers and guarantee the quality of each coil component.

Applications:

  • Inverters, Power Inductors, Winding, Transformers, Motors, Wave Filters, Capacitors and Circuit breaker

Measurement Items:

  • HARM, HFLT, Total Area, Area size comparison, Waveform comparison, Flutter & Corona
