“…The other half of the outlet enables the air outside to enter the chamber, i.e., there is a counter-flow of gas at the outlet. This agrees with previous experimental results, 2 which suggested that the plasma outside the chamber is wedge shaped. This implies that escaping plasma from the chamber passes through only half the outlet.…”

Based on the thermo-physical properties of plasma air, the temperature and flow fields of an insulator–arrester with a multi-chamber system are investigated using three-dimensional computational fluid dynamics. The plasma flow is assumed to be steady incompressible laminar flow and in local thermodynamic equilibrium. The results obtained show that the arc inside the chamber bends downwards, indicating that the Lorentz force induced is directed away from the exit and pushes plasma air down. The outlet also provides passage for plasma flow both in and out of the chamber.

“…Recently, an insulator-arrester with a multi-chamber system (MCS) was proposed that combines the properties and functions of the insulator and arrester. [1][2][3][4] With the installation of an MCS, shield wiring is no longer needed bringing down the cost of towers.…”

“…Experiments performed on real devices have consistently demonstrated two modes of current quenching [1][2][3]: in the case of current zero quenching (ZQ), current will flow through the device until it passes through zero due to the vanishing grid voltage. This results in arcing times of the order to 10 ms.…”

We develop a consistent model for a line lightning protection device (LLPD) and demonstrate that it can explain the two modes of current quenching-impulse quenching and current zero quenching-observed in such devices. A dimensional analysis shows that impulse quenching can always be obtained if the power loss from the electric arcs is large enough as compared to U I f 0 , where U 0 is the grid voltage and I f is the maximum follow current after a lightning strike. We further show that the two modes of quenching can be reproduced in a full 3D arc simulation coupled to the appropriate circuit model, which allows us to analyze the power loss from the arc in greater detail. Because of the high temperature, the main mechanism of power loss is radiation which has to be correctly modeled in order to obtain physically meaningful results. The results will allow us to use numerical simulations to optimize the quenching ability to LLPDs in the future.

Abstract. Two distinct modes of follow current suppression were observed in multi-chamber systems (MCS) under lightning overvoltage: Zero Quenching (ZQ) and Impulse Quenching (IQ). Sufficiently lower erosion of electrodes and evaporation of discharge chamber walls makes the IQ more preferable as a mechanism of arc quenching. Since experimental search for best MCS design is both difficult and expensive numerical modeling is considered as a prospective method for geometry optimization. Several steps were made towards development of efficient arc model. This article highlights most important results of arc quenching simulation and current status of arc model development.
