Impulse voltage test systems are available for factory testing in three product lines (L, M, and G). Voltages ranging from 10 kV to 5700 kV (LI)/4500 kV (SI) can be generated depending on the product line.
There are test systems for voltages up to 1900 kV (LI) for on-site testing available.
The standard test system consists of an impulse voltage generator and three components (voltage divider, chopping sphere gap, and overvoltage correction). HIGHVOLT offers the Connection Point, a space-saving solution combining all three components in one device.
The standard version of the test systems has a digital transient recorder, type HiRES.
It delivers precise voltage measurements and offers a variety of features for controlling the impulse voltage system as well as capturing and evaluating measurement values. The HiRES itself offers no control; it comes with the software of the IPC.
Application
To generate impulse voltages for testing:
Transformers
Cables
Gas-insulated switchgears (GIS)
Arresters and other high-voltage devices
For material testing in research or training programs
For both factory and on-site testing
Benefits
Features a compact design to save space in the test bay
Generates impulses with a low level of overshoot due to the low self-inductance of the impulse voltage test system
Option of using the system to generate impulse currents
Configuration of the generator for the G product line saves time due to walk-in accessibility and storage of the resistances inside the generator
More possibilities to save space and time when used in combination with the
