engineering recuitment MP Vyapam Sub Engineer Mock Test 2024 Power Systems Transmission and Distribution Overhead Insulators
Safety factor of insulator is:
1
\(\rm \frac{Flash\ over\ voltage}{puncture\ strength}\)
2
\(\rm \frac{Flash\ over\ voltage}{puncture\ strength}\times100\)
3
Puncture strength × Flash over voltage
4
\(\rm \frac{puncture\ strength}{Flash\ over\ voltage}\)
