Brilliant, thank you

This is a calculation I have to do regarding a college project.The 40ka is the maximum pscc that can be given by the DSO's utility transformer, please note this is based on an Irish system, however everything should be the same, out installation methods are the same as the BS regs. All XLPE's...

Well due to the size of the load, im using a utility transformer, assuming a maximum of 40KA. Maybe I should have included the cable runs R1/1 = 10meters of 185mm sq XLPE R1/2 = 40meters of 120mm sq XLPE R1/3 = 50meters of 4mm sq PVC R2/2 = 50meters of 2.5 sq PVC R2 = 40meters of 70mm sq...

Pscc has a maximum of 40ka at the transformer,which according to Amtech gives a Ze of 0.0058 ohms. Sorry I wasnt too sure about which section to post in. Im trying to compare a manual calc with Amtech for a project.

Hi lads, im wondering if someone could clarify a question I have regarding doing a manual fault loop impedance calc for the circuit shown below (t-n-c-s). As you can see the fault is taking two different paths back to the utility transformer, im trying to determine which path I should base my...
