Condition: like new (used), GBS Test Pulse Rev. 3 Pulse Generator for Long-Term Insulation Tests The test pulse design is designed for long-term insulation tests on test objects with capacitances up to 6 nF. Converter for High-Voltage Test Transformer · Internal sine wave generator: 50-200 Hz. · Pulse width modulation of the sine wave from 16-24 kHz via full bridge. · Converter voltage adjustable from 0-600 V, Imax=2.6 A, maximum power 1.3 kW · Pulse current limit 110 A (cut-off threshold) Pulse Transformer Control Nwjdpju Egz Rjfx Ag Nsc · Control via full bridge · Full-bridge power supply adjustable from 0-1000 V, 1.3 A max. · Pulse current limit 100 A (cut-off threshold) Pulse width 20-120 μs, nominal 94 μs, adjustable · 2 selectable series inductors (150 μH, 300 μH) to adjust the pulse width and rise time to the load capacitance and voltage. · Pulse repetition frequency (0.1 – 2.5 kHz), adjustable. · Polarity: Adjustable positive, negative, or alternating depending on the polarity of the sine signal. · Cosine-shaped pulse at the transformer output Pulse transformer cascade · Output transformers in a 5-way cascade circuit. · Total transformation ratio selectable as 1:7.7, 1:10, or 1:15 via taps. Maximum output voltage 15 kV with possible load capacitances of: * 6 nF with a pulse width of 73 μs at a repetition frequency of 2.5 kHz * 10 nF with a pulse width of 103 μs at a repetition frequency of 1.25 kHz · 1:1000 parallel voltage divider. · Overvoltage limitation at approx. 20-23 kV through parallel spark gaps. · Thermistor for overtemperature detection in the first transformer stage. · Ground-side current measurement socket 100 mV/A. Breakdown detection, test · If the maximum bridge currents for the transformer controls or if the maximum currents of the bridge power supplies are exceeded, the high voltage is switched off. · The device has a resettable operating hours counter to determine the test time.
