SSC JE Electrical 2019 with solution SET-1 The annual load factor of a generation station is equal to (No. of units actually supplied per year) ⁄ (Max. possible demand) (No. of units actually supplied per year) ⁄ (Max. possible demand × 8760) (No. of units actually supplied per year) ⁄ (Max. possible demand) (No. of units actually supplied per month) ⁄ (Max. possible demand × 8760) (No. of units actually supplied per year) ⁄ (Max. possible demand) (No. of units actually supplied per year) ⁄ (Max. possible demand × 8760) (No. of units actually supplied per year) ⁄ (Max. possible demand) (No. of units actually supplied per month) ⁄ (Max. possible demand × 8760) ANSWER DOWNLOAD EXAMIANS APP
SSC JE Electrical 2019 with solution SET-1 Hunting occurs in a/an motor Synchronous DC shunt DC series Induction Synchronous DC shunt DC series Induction ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Sudden changes of load on synchronous motors may sometimes set up oscillations that are superimposed upon the normal rotation, resulting in periodic variations of a very low frequency in speed. This effect is known as hunting or phase-swinging.
