QUESTIONS WITH VERIFIED SOLUTIONS
●● Reclosures
Answer: Operate 3-4 times, 3rd and 4th time is slower to allow
sectionalizer to open and/or allow fuse to burn.
●● Do Sectionalizers operate under load?
Answer: NO, they only operate when the reclosure is open.
●● Resistance is opposition to current flow in a conductor. What
determines resistance?
Answer: Length, Material, Temperature, Size of the Wire.
●● Define Impedance.
Answer: Total Opposition to Current Flow in an AC circuit. Consists of
Capacitive Reactance, Inductive Reactance, and Resistance. Symbol is
Z, and it is measured in Ohms.
●● What is Corona?
Answer: Corona is when a conductor is at a potential above the
dielectric of air surrounding it.
,●● ELI
Answer: Voltage (E), Leads Current (I), in an Inductive Circuit.
●● ICE
Answer: Current (I), Leads Voltage (E), in a Capacitive Circuit.
