Low voltage on Phase _Fixed

Featured Replies

I have a unique problem.

Ok so I only have single phase , most around me have 3 phase..

After load shedding last night I came back on with 110V so one phase is down.  From what I can gather it is affecting 2 transformers on our road, so iti s probably the main overhead 11KV lines.

My Inverter is running fine with eskom power ( 110) on, most appliances function fine. Rancilio Coffeee machine is fine, but grinder not, garage door motors not. some led lights flicker like crazy other are fine. 

Switch off Eskom grinder, garage door works, lights brighter so seems like voltage goes up. So when eskom is above a certain voltage, the  Inverter feeds eskom through.

 

Update before posting

I suddenly thought there must be a setting.. as below , select the UPS range and its fixed...

Most appliances can run from low volts but fridges motor can get damaged from low volts so yes try stay on battery or switch of fridges .

On Monday the opposite  happened part of town had high volts of 380 volts the few that got  inverters the  appliances were saved as the inverter switched to battery mode the houses that did not have inverter there tvs , microwaves , gate motor and more burnt out so the house with inverter were okay

That's not how phases work, at least outside North America and Japan.

Something must be really badly wrong with the distribution system.

Coulomb , been here for 34 year and it is a regular occurrence. I measured the voltage on the DB below Transformer Red was 110V. Different transformer one the road had no power but could not get more info 

Eskom only ever repair when it breaks, never improve the system.. Now we getting many more houses and flats.. only gonna get worse.
