Abstract
This project aims at design of test kit for DC Overvoltage Protection Unit, which is
used in aircraft to prevent various electronic devices from damages which may be
caused due to overvoltage. This Protection Unit is used to control the operation of
an external, latching-type relay present in the voltage regulator, This relay de-excites the
generator if an overvoltage condition occurs.
The test kit designed for the DC overvoltage protection unit basically simulates the
overvoltage condition across the DC overvoltage protectlion unit. Due to this overvoltage
simulation the unit operates and excites the relay provided in the test kit, and thus the protection
unit disconnects the supply. The test kit is also used for measuring the time taken by protection
unit to operate. The details of project have been discussed in following chapters.
