the distance from my office to d.g is aprox 400mtrs and
voltage drops ibn my office near about 40 volt what should
i do p[ls suggest.
Answer Posted / sabale.dnyanehswar@gmail.com
IF U ASKING ABT DC Voltage then ans is
1. u have to increase the sq.mm size of the cable. i.e if
u r laid cable size is 16 sq.mm. u can go to 25 sq.mm.
2. u have to increase u r battery Amphour rating . by
replacing it with higher rating.
if u asking abt AC voltage:
1. check the DG set terminal voltage if voltage is not
proper then check at AVR terminal. if there also not ok.
then check it with another AVR card.
2. if AVR is OK then check any leakage of cable with taking
megger & continuty with earth.
3. if problem is found in cable then replace with new one
or increase the rating of cable.
if everythink is ok. then take voltage at receiver end with
out load. one by one increase the load at every time
voltage reading. if found prob. in another ckt. rectify it.
The range should be +- 5% should be accepted.
