Video Description

One of the most amazing things about three phase electricity is that in a perfectly balanced system a neutral wire isn't needed. In this video, Joe Robinson shows how the neutral current sums to zero when an equal load is connected to each phase. This helps to explain why the neutral conductor in a three phase cable is the same size as the other phases and why some industrial sockets don't have a neutral connection. This electricians Q&A follows from our review of the Variabox, from CEENORM, which is a flexible power distribution system for industrial electrical installations. 👉 https://youtu.be/9PFG-LUFKHI ================================ 00:00 Industrial Electrical Installations 00:42 Does current flow in the neutral conductor - yes & no? 00:50 Neutral current in a ingle phase circuit 02:00 Neutral currents in a Three Phase circuit 04:09 Lower than expected current? 05:08 No neutral current? 05:48 Why does this happen? 06:30 Electrical installations with no neutral ================================ ================================ 🔦 More electrical Q&A videos from eFIXX 👉 https://www.efixx.co.uk/electricians-questions ================================ 🆕 FREE CPD Learn about new applications, regulations and best practices with our FREE CPD modules. - New modules are released monthly, covering everything from surge protection to lighting. 👉http://hub.efixx.co.uk/CPD​ ================================ 📍SUBSCRIBE TO THE CHANNEL eFIXX helps electricians, electrical contractors, building services engineers, and electrical apprentices.
