II.Brief description
GW-IT15 series pulse coil tester is specially designed for the testing needs of wire-wound components, the use of a high-voltage charging of a small capacitor (low test energy) and the coil to be tested to form a parallel resonance of the RLC, by the attenuation of the oscillating waveforms,through as high as 100Msps (can be customized to 200Msps) and the precision of the sampling processing and analytical techniques, can be tested to the coil from the body of the insulation is bad (turn-to-turn short-circuiting, short circuit between layers, insulation performance degradation, etc.), so that component manufacturers and users can more effectively for product quality control. Short circuit between turns, short circuit between layers,insulation performance degradation, etc.), so that component manufacturers and users can be more effective for product quality control.
GW-IT15 series instrument measurement speed, test waveform repeatability, can be widely used in motors, frequency transformers, relays,
switching power supply transformers, demagnetization coils, etc. by the enameled wire wound components; GW-IT15 series can be applied to automated test system to greatly improve the test efficiency.

IV.Advanced Pulse Test Principle
The so-called"pulse testing of wire-wound components" is a non-destructive, high-speed, low-energy voltage pulses applied to the test
piece to analyze and compare the waveforms of the good and defective test waveforms for the purpose of judging the GW-IT15 series of large screen,ultra-high sampling rate, high-performance processing technology, so thatthe customer intuitively distinguish the difference between defective and good products. The GW-IT15 series has a large screen, high sampling rate and high performance processing technology.
V.Powerful corona test function
Can be customized up to 200Msps high-speed sampling rate, accurate extraction of corona information, and is equipped with corona display function, corona display at a glance, the performance of the product to do to prevent problems before they occur, greatly improving product quality.
VI.Unique destructive testing capabilities
Destructive test is a test mode that starts from the starting voltage, takes the step voltage as the voltage step, ends with the termination voltage and combines with the comparator for comparison, which is used to judge the limit voltage withstand value of the tested parts, which can help customers to know the voltage withstand value of their own products and serve as the reference for setting the test voltage.
VII.Expanded dual-channel, quad-channel testing capabilities
GW-IT15S-2 dual-channel, GW-IT15S-4 four-channel can meet the customer on the Y-type winding (three-phase four-wire), three-phase
three-wire winding test needs, motor winding test once, to avoid multiple switching test troubles, testing fast, efficient and cost-effective, widely praised by customers.
It can also be equipped with an external multi-channel scanner box, such as a typical 8-channel scanner box.
