power reduction but not outage??

stooge

During the storm last night the electricity seemed to be reduced but did not go off completely. Anyone any ideas on how this could/would be done or if I should be looking into a local issue within the bounds of the property?

Some symptoms/facts:

• Most houses in the area seemed to be off but are sort of on a branch and the end of a line. The houses either side of us had a supply but not sure yet if they had reduced power.
• lights in certain parts of the house were running dim whereas some others were fully lit
• Kitchen appliances were running slow e.g. toaster/kettle taking ages to heat up
• Electric shower turned on but again was very slow to heat up
• broadband/tv all functional
• tried isolating fuses by turning most off then on 1 by 1 but symptoms above remained

House at the end of the line has solar panels and give back to grid. unsure if they have battery storage but from what I gather that should be isolated during outages.

Any theories??

Probably 1 phase down on the higher voltage side of transformer supplying the affected house/ houses.

Nothing to do with the solar panels, once the grid goes down the inverter stops any possible power feeding back into it unless a cowboy fitted it with no regulations adhered to but even then to supply power to half a street would take a massive solar array, not something a normal house would have.

Voltage Reduction. Can be very harmful to motorised appliances such as fridges. Would be wiser unplugging high value electricals during such an event.
