LADWP ELECTRIC STATION
OPERATOR (CIRCUIT
BREAKERS, DISCONNECTS,
TRANSFORMERS)
disconnects - ANSWERS-__________ are hook-stick operated and
gang-operated.
bank - ANSWERS-__________ switching is performed in
substations: to provide adequate capacity for customer load, to
provide an alternate source for customer load when equipment
maintenance is required, and to search for 4.8kV grounds.
distribution - ANSWERS-__________ stations banks are configured
with either one or two 4.8kV (low side) circuit breakers (CBs).
closed - ANSWERS-Disconnects, through which current normally
flows, must remain __________ at all times.
open - ANSWERS-Disconnects through which current does not
normally flow usually remain _________.
magnetizing - ANSWERS-A certain amount of current flows when a
bank is first energized. This current is known as __________ current.
, magnetizing - ANSWERS-When energizing large banks, __________
current can be considerable and may negatively affect customer
service if not performed properly.
high - ANSWERS-Proper procedure requires banks to always be
energized from the __________ side.
paralleling - ANSWERS-The act of connecting two circuits together
so that current can simultaneously flow through both of them in
known as __________.
low - ANSWERS-In distribution stations, load is transferred to a
paralleled bank by normally opening the bank __________ side CB or
CBs.
blocking - ANSWERS-Bank-in-Service caps are __________ devices
that are applied to the control handles of closed bank CBs.
customer - ANSWERS-Operators, among others, are charged with the
responsibility of providing good __________ service. This means no
unplanned service interruptions to customer load.
switching - ANSWERS-Good operators plan ahead by preparing
__________ plans.
