Ground a Generator? Simply Explained for Non-Electricians
Webb21 apr. 2024 · In distributed generation projects, I often get asked about the purpose of including Neutral Ground Reactors (NGRs). An NGR is a series inductance (a coil) that is installed between the "Wye ... Webb18 jan. 2015 · The 0.9 Ohms resistor connected across the 240V secondary of the neutral grounding transformer would appear as (700 x 0.9 = about 630 Ohms). And, the added advantage is that this resistor needs to be insulated only for 240V. A reduced Ohmic value resistor, with a reduced insulation rating is cheaper. And, the neutral grounding … porthcawl live camera
