What happens to the speed of a 3 phase motor with an "unbalanced
load"? -ANSWER-It's called single phasing and will burn/heat up the
motor quickly.
In excess of what voltage shall insulated tools and gloves be worn for? -
ANSWER-120v
A 3 phase motor shows 15 FLA.(Full Load Amperes) You have readings
of 15.6, 16.1 and 15.9, what is the condition of the motor? -ANSWER-
The motor is overloaded.
4-20 mA output for a device with a range of 0-63,535. Read is 6 mA.
What is the measurement reading? -ANSWER-7941.875
Ladder Diagram -ANSWER-Ladder diagrams are specialized schematics
commonly used to document industrial control logic systems(PLCs).
They are called "ladder" diagrams because they resemble a ladder, with
two vertical rails (supply power) and as many "rungs" (horizontal lines)
as there are control circuits to represent.
,How to measure 4-20ma with a digital multi meter(dmm). -ANSWER-
Disconnect one wire of the loop and connect the DMM in series.
How far from the disconnect should a pump be located? -ANSWER-
within sight and not at a distance greater than (50 ft) from equipment.
The most important requirement for good
maintenance of motor starters is: -ANSWER-proper lubrication
A reversing starter reverses a three-phase
motor by interchanging: -ANSWER-Any two of the phases
What kind of protection is provided in a manual across-the-line three-
phase motor control? -ANSWER-Overload protection only
The drawing that provides a view of the entire
system in process control is the: -ANSWER-P&ID also known as pipping
and instrument drawing
The most commonly used type of diagram in
process control is: -ANSWER-piping and instrument drawing
, When Taking a flow measurement the measuring device is performing
what type of calculation? -ANSWER-Root mean square
A 480V, 3 phase motor, Delta connected, has one leg shorted, what will
the resistance be compared to the other legs -ANSWER-Lower
A 12V battery rated to provide 1amp for 20 hours across a 2000w load.
How long will the battery continue to produce an output? -ANSWER-
100 hour
How is true power expressed? -ANSWER-KW
You took apart a 3 phase motor, meggered a motor lead to the housing,
and read 5000 ohms. What does this mean? -ANSWER-Motor is fine
What drawing does a PLC use? -ANSWER-Ladder
What does NFPA820 cover? -ANSWER-Wastewater and Collections
When should you megger a motor for its lowest insulation readings? -
ANSWER-Immediately after shutting down equipment.
