Partial discharge tester ST 4000B

for high-voltageinsulationresistance

• Desktop device 19" / 6 HU • Surge voltage test: 100 - 6.000 V • Surge capacity: 18 nF, optional: 40 nF, 100 nF, 200 nF • Partial discharge measurement according to IEC 61934 • Evaluation method: Error area, differential error area, tolerance band method • High voltage test DC: 100 - 6,000 V / 10 mA  • Insulation measurement DC: 100 - 6,000 V / 10 GΩ / kV  • Resistance measurement (optional): 20 mΩ to 200 kΩ, max. 1A • Internal matrix: 4 phases + PE, 4-wire Winding goods such as stators, coils or transformers can be tested precisely and conveniently with the new ST 4000B surge tester. Short circuits and insulation faults within a winding can be detected before the fault affects the DUT. Failures of electric motors and the associated recalls can thus be avoided. Guaranteed freedom from partial discharge of the test, switching and connection technology over the entire voltage range of the test device. The test device is operated with an internal Windows PC and the easy-to-use DAT 3805 data acquisition software. This means there are no limits to test plan creation and result storage. Network integration is not a problem, as the embedded Windows 10 IoT Enterprise 2019 LTSC used can be regularly supplied with security updates. The test sequences can be designed as required and then carried out automatically. Additional test and measuring devices from SPS electronic can be easily integrated via the external power supply option. The test device can be expanded to include high-precision resistance measurement without requiring any additional space.
