What Is TDC Of a Piston? 7 Ways To Find The TDC Of an Auxiliary Engine

            TDC (Top Dead Center) means the upper most position of piston in the cylinder of an engine. It is the point from which ignition system measurements are made and the firing order is determined. Engineers are using different methods to find out the TDC of an Auxiliary engine. Here  you can have a look at some of the  methods to find out the TDC.

SOLAS Regulations For Steering Gear, Relief valve and Steering Gear Control

Open Circuit, Short Circuit & Earth Fault, Effects And How to find Circuit Fault

Open Circuit Fault
       An open-circuit faults is due to a break in the conductor, as at A (Fig), so that current cannot flow.
Effects:- An Open circuit fault will not allow the motor to start. If the fault occurs in 1 phase when the motor is running, the current in other two phases will increase and burn out the motor
