Abstract:

In the present paper, the streamer inception voltage simulation method is described and implemented.

Physical model-based streamer simulation demanding tremendous simulation time and it is also difficulty to be used for real engineering situation.  In this paper we use the streamer criteria approach which provide a fast, accurate and easy to use method to evaluate the streamer inception voltage.

The simulation is based on electrostatic simulation for 2D/3D construction.

Based on the electrostatic simulation results, the electric field line tracing is performed from defined staring point.

The field line tracing has two methods: in insulation gas space and along the solid insulator surface.

Based on the electric field value along this field line and the streamer inception criteria, the streamer inception voltage can be calculated, which is influenced by effective ionization coefficient properties of insulation gas, the streamer constant, the electric field distribution, the pressure of the insulation gas.

Three validation simulations, Plate/Plate, Rod/Plate and Sphere/Sphere configurations are made and compare the results from the literatures, and all have good agreement with the results from literatures.

Two real tests were validated with simulation and tests, both case the simulated and test results are agreed with each other.

It provides an easy accurate and fast way to calculate the streamer inception voltage which can support the dimensioning of high voltage devices in general.
