transformer keeping the voltage constant?
|in an open circuit. test there is no
but secondary. ia open then no
urrent have to flow
but there a smaller current flows
|how work the lighting arrestor?

|I have 500A load (WHICH IS SEPARATE MDP PANEL),an MCC panel
with 4000A Breaker.Already I have 2500A load.Can I connect
this load directly to the Busbar since I have PROTECTION IN
MY MDP Panel ?
|what will happen when ac is applied
|I have a question, I visit 01 site and face a problem,
there is 2.5 ton Air Con working, when air con compressor
is running at that time rectifier voltages are increasing
upto 290-295 v and rectifier is giving main high alarm
(rectifier is APC single phase), before starting compressor
rectifier voltages was 230v. when air con is going off
rectifier voltages are decreasing smoothly at its actual
Load on Genset phases is this: Red-13.5 amp AC (Air Con
load), Yellow-1.7 amp AC (BTS lights etc.) and Blew-4 amp
AC (telecom system load),
Genset phase to phase and neutral to phase voltages are
These are 10 sites having same system and same rectifier
APC brand at every site 02 genset are working but the
problem is same at all these 10 sites.
What will be the reason behind???
