Since I`m yet to receive a reponse to my post, I will be pleased if someone can g?ve me a link to a previous post on the cable armouring. Thanks

Our specs say the cable armour shall be of a non-magnetic material. A supplier has proposed using galvanized steel. My company has asked the supplier to replace the galvanized steel with Alum?n?um. S?nce the supplier ?s sourcing the 1x630sqmm 33kV cables from an experienced manufacturer,I...

Waross, the pumps run at 0.433kV. There are a total of 4 transformers with a total capacity of 2860kVA (2x630 + 2x800).

Thanks Slavag, jghrist. The kVAR values increase when the pump are running. I want to find out the source of the kVARs. If you have huge motors in the "standby" mode, does it draw any VARs?

Thanks for the quick response. However, I want to make the following clarifications: 1)I am monitoring the 11kV incomer panel of a 6MVA 33/11kV transformer. 2) The pumping station has offices and lighting system. Even when there is no pumping going on, there is still some load being served. (The...

I installed a power analyzer to monitor the kVARs being drawn at a Water Pumping (Booster Station) site. When the pumps are not running, I get power factor (PF) as low as 0.111 (lagging). The PF rises to about 0.9 when the station is pumping water. I am wondering why I get 0.111PF when the pumps...
