substation transformer
Pole top transformer
voltage regulator
Step up transformer
In a typical distribution system, electricity at ____________________ voltage is supplied to a customer.
primary
nominal
peak
secondary
Primary distribution voltage is:
applied to a distribution system by a substation transformer
the voltage of the electricity supplied to the customer
applied to distribution lines in a service area
True or False A transformer improves the overall efficiency of a distribution system by increasing the amount of usable power that can be supplied to a customer.
True
False
During high voltage surges, _______________________ provides a way of redirecting excess current to the ground.
surge destroyers
surge arresters
surge eliminators
current protectors
Voltage applied to the primary winding of a distribution transformer is usually higher in value than the voltage induced in the secondary winding.
True
False
In a typical distribution transformer:
primary voltage is applied to the secondary winding through connections at the transformer core
primary distribution voltage applied to the secondary winding induces a secondary voltage which is supplied to the customer.
primary voltage applied to the primary winding induces a voltage in the secondary winding
primary distribution voltage is supplied to customers through the secondary bus.
Distribution transformers can be buried underground or mounted overhead on utility poles
True
False
A 15 KV rated lightning arrester is typically larger in size than a lightning arrester rated at 10 KV.
True
False
A way to determine if a power line is operating at 7.2 kv or 14.4 kv is to look at the size of insulators and lightning arresters.
True
