I BOUGHT A HAVELLS ACCL WITH GENERATOR STOP FASCILITY(i.e- BASICALLY IT IS A AUTO CHANGE OVER SWITCH) FOR MY HONDA EXK 2000S HOME GENERATOR (WHICH START IN PETROL & RUN IN KEROSENE). ACCL HAS 8 POINT. 2 FOR MAINS(PH & NUE), 2 FOR LOAD, 2 FOR GEN AND 2 FOR IGNITION POINT(X1 & X2). THE IGNITION POINT IS SPECIALLY FOR AUTO ENGINE STOP WHEN MAINS POWER RESTORE. I CONNECT THIS X1 & X2 POINT TO THE GENERATOR STATER MOTOR & EARTHING POINT. BUT WHEN MAINS FAILS THE GENERATOR COULD NOT START, BUT WHEN DISCONNECT THOSE X1 OR X2 POINT, THEN THE GENERATOR START. BUT WHEN MAINS ON THEN THE GENERATOR SHOULD START, AND WHEN I OFF THE MAINS THE GENERATOR AUTOMATICALLY STOP. PLESE HELP ME HOW I STOP THE GENERATOR AUTOMATICALLY WHEN THE MAINS RESTORE.2 8607

How a capacitor discharge weld power supply works? what is the use of a pulse transformer?
In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
