Refrigeration & Air Conditioning Technology
Sometimes it is desirable to use line-voltage thermostats to stop and start
equipment. Some self-contained equipment does not need a remote thermostat.
To add a remote thermostat would be an extra expense and would only result in
more ...

It is not possible to calculate line voltage at any instance of time without a
complete train performance and traction supply system simulation. This will
automatically occur if a simulation is used to determine the minimum headway.
Otherwise it ...

Handbook of Electric Motors
This difference is small, even under full-load conditions, unless the motor is very
small or the line voltage quite low. As a first approximation, line voltage V may be
taken as being equal to the internally generated voltage £„, especially under ...

Electric Power Distribution Systems: A Nontechnical Guide
The line reactance is 0.66 ohms/mile/conductors; and the line-to-line voltage is
4,160 V. The rise then becomes: (135X2X0.66) Percent Voltage Rise = — = 1.03

Protective Relaying: Theory and Applications
The voltage transformers must have a primary voltage rating equal to the line-line
voltage, since this is the voltage that will be impressed on the two unfaulted
phases during a line-ground fault. Under normal conditions, the voltage across
the ...

Overhead Power Lines: Planning, Design, Construction
The highest limit practically recommended for line regulation is in the range of 5
to 10 %, depending on the line voltage and on the reactive power compensation
available. Table 1.2 contains the highest system operation voltages.

Most thermostats are either low- voltage, line-voltage, or electronic. Low-voltage
thermostats receive power from a transformer that converts 120-volt household
current to 24 volts. Line-voltage thermostats use the same power source as the ...
