lower voltage under voltage tripping mechanism
The aim of this
project is to develop a low voltage and high voltage tripping mechanism to
protect the load from damage. The fluctuation in AC mains supply is frequent in
homes and industries. The sensitive electronic devices in these conditions can get
easily damaged. It is preferable to have a tripping mechanism to protect the
load.
This
proposed system will trip the load in the event of the input voltage falling
below/above a set value. Two 555 timers are used as window comparator. This
delivers an error output if the input voltage to them crosses the range beyond
the voltage window. A relay is then operated to cutoff the load for safety
reasons. A lamp is used as load in this project.
The
concept in future can be extended by integrating an alarm, which sounds when
voltage fluctuations occur. It can also be interfaced with a GSM modem to
convey alert message to the user via SMS
to take appropriate action.
