during high voltage surges.
ANSWER b) surge arresters a) surge destroyers b) surge arresters c) surge
eliminators d) current protectors
2-1. Mark the appropriate ANSWERs. Which three components are present in
the majority of distribution transformers?
a) Primary winding b) Bolts for mounting
c) Fuses d) Secondary winding
, f) Core: A, C, and f answers
2-2. Is it true? In a distribution transformer, the voltage induced in the
secondary winding is typically lower than the voltage delivered to the main
winding. ANSWER: True
2–3. To finish the following sentence, circle the appropriate ANSWER. Typical
distribution transformers look like this:
a) Through connections at the transformer core, the primary voltage is delivered
to the secondary winding.
b) A secondary voltage that is supplied to the customer is created when the
primary distribution voltage is applied to the secondary winding.
c) When a primary voltage is applied to the primary winding, a secondary
winding voltage is induced.
d) Customers receive the principal distribution voltage via the secondary bus.
e) (a) as well as (d) - ANSWER c) When a primary voltage is applied to the
primary winding, a secondary winding voltage is induced.
2. True or Untrue. Distribution transformers can be installed on utility poles
above ground or buried underground. ANSWER: True
3-1. To finish the following sentence, circle the appropriate ANSWER. A
regulator of voltage:
a) keeps the distribution voltage within a predetermined range.
b) changes what it receives in terms of voltage.
c) has the ability to receive, store, and release a charge.
d) provided feeders with power at distribution voltage. ANSWER a) keeps the
distribution voltage within a predetermined range.
3-2. Is it true? When a voltage regulator's primary and secondary windings are
connected in series, the primary winding acts as a component of the secondary
winding. ANSWER: True
3–3. To finish the following sentence, circle the appropriate ANSWER. In a
standard voltage regulator, the primary winding receives voltage via the "load"
connection.
b) The "line" connection is used to supply the regulator with uncontrolled
voltage.
