A certain load varies as follows for 269 days per annum: 436 kVA at a power factor of 0.819 lagging for eight hours per day. 208KVA at a power factor of 0.836 lagging for eight hours per day. 131 kVA at unity power factor for eight hours per day. For the remaining time of the year, the load varies as follows: • 90 kVA at a power factor of 0.822 lagging for eight hours per day. • 25 kVA at a power factor of 0.866 lagging for eight hours per day. • No load for eight hours per day. Determine the average value of the load per annum Determine the annual load factor (KL) Determine the Rms value of the load per annum in kVA Determine the form factor (K)
