VOLTAGE MONITOR & SINGLE PHASING PREVENTOR
voltage fluctuations, single phasing and
frequent disappearance and performance of
the mains supply causes a lot of head ache
to a former. Whenever the supply voltage
reappears after remaining OFF for a certain
duration, the farmer has to abandon al his
other jobs to reach the starter for starting
the pump motor. Sometimes he has to walk
through his fields covering a long distance
to start the motor.
the above problems the voltage sensing type
Single Phasing Preventor of the SAVE series
has been specially developed by PRINTRONIX
ENGINEERS PVT. LTD.
carefully designed to monitor the occurrence
of any abnormality in the 3-phase supply and
accordingly stop the motor. SAVE can be
connected in such a way so that when the
normal supply is resumed the motor starts
designed to work on the principle of voltage
sensing without any requirement of NEUTRAL
or EARTH connection. Because of this design,
it can be used with a motor of any rating.
It also ensures total protection by
supplementing a current sensing protection
already provided by modern overload relays.
connected for MANUAL as well as
AUTOMATIC operation of the pumps.
