OKAY. Voltage drop at the main circuit breaker, this excludes the bad connection ...
You call "discontinuous suction" when in very cold weather, the boiler recharges outside of the full programmed in the evening at 20 pm, I suppose ... Enedis had announced difficulties on the network in very cold weather, but rather in the evening. With my means of load shedding a slight voluntary lowering of the voltage (which consumes less). It is also possible that at this peak in consumption around noon, the network is in difficulty. A battery of heat pumps in the area that are running at full speed, a small workshop of je ne sais quoi on the same line, etc ...
