SPS-ELECTR ST 4000B
The ST 4000B is a benchtop model for surge testing windings, such as stators, coils, and transformers. It is used to detect short circuits and insulation faults in windings before they can cause problems in the finished product.
It operates with surge voltages from 100 V to 6,000 V and has an internal surge capacitance of 18 nF. Other capacitances can also be selected to adapt the test to the specific task. In addition, it supports partial discharge measurement according to IEC 61934, which is relevant for more precisely assessing testing, switching, and connection techniques.
In practice, it is an instrument for test environments where repeated and consistent measurements are desired. Test sequences can be built and run automatically via the internal Windows PC and DAT software, and results can be saved and integrated into networks. The device has USB, HDMI, and Ethernet/LAN, allowing it to seamlessly integrate into a modern test setup.
In addition to surge testing, the ST 4000B can also be used for high-voltage DC testing and insulation measurement in the range of 100 V to 6,000 V. The DC high-voltage test has a current limit of 10 mA, and the insulation measurement is specified at 10 GΩ per kV. This provides a single platform for multiple types of electrical testing.
Typical applications
- Testing of stators, coils, and transformers
- Checking for short circuits and insulation faults in windings
