Effect of electrical arcing on the system voltage

What will be the effect of Electrical arcing (between phases or between phase and neutral) in a 415V three phase system in the downstream voltage... Will it just act as a load ( let's say the arcing was highly resistive and did not trip the system and continued ) or will it cause any increase in system voltage ..? If it causes a rise in system voltage how

• Grid Protection is performed by sensing current vs time parameters with ARC clamps making OVP resistive loads. Then correction depends on these parameters for fault protection then recovery fault detect. Usually 3ph shutdown then reclose with 2 or more retries in 1 minute or less. Oct 16 '19 at 23:17
• @TonyStewartSunnyskyguyEE75 can you elaborate it ? Oct 16 '19 at 23:19
• @TonyStewartSunnyskyguyEE75 I would like to know if an arcing can result in voltage spike in any way Oct 16 '19 at 23:20
• Arc resistance depends on electrode diameter which affects current amplitude but then density when focused in air resulting in higher amp density (spark thickness) and also lower negative incremental resistance or -ESR like a bigger Triac, thus a spark can trigger a breakdown but gap determines the "HOLDING current" to sustain the arc and inductance at next zero crossing which results in voltage drop if the holding current can sustain the arc. You see this action by a spark plug and striking an arc with a wire and then spreading the arc until it breaks as the ESR rises and current reduces Oct 16 '19 at 23:24
• But short the grid with an big transformer low 50%V rated on grid can draw an arc with a wire and burn the wire and maybe trip your breaker. That would require a quick arc that causes hum ,then release transformer to create an arc before breaker trip and sustain an arc (but unsafe until you can compute the results) Oct 16 '19 at 23:29
