Draw a SLD for main panel for school having connected load of 1200kw and emergency generator 200kw.also show the increase of additional load of chiller 225kw in the lv panel indicating meter postion size of transformer ,cables and capacitor bank.
a 230v transformer with step down ratio 19:1.it has 2000turns on primary and rated 25va calculate max primary current no of secondary turns volts/turn
ELECTRICAL ENGINEER TEST IN FEWA ANY ONE HAVE KNOWLEDGE ABOUT THIS?????????
why we use single core 630mm2 cable for transformer secondary side
Dear all i want to know SEWA Electrical Supervisor Licence test Previous Year Questions ? If any body know please send to me zohairaukllah@yahoo.com
A 2083kva AVR was tested, phase to ground shows continuity, what is the implications
Different types of relay fault which phase sequence??
If 22 KV HT line, Current transformer is 25/5 then how to calculate multiplying factor.
how to compare with Relay settings for HT< panels, RMU panel, and PSS CSS transformer?? 1) Load amps, 2)Tripping time, 3) CT ratio, 4)Cable size 5) Transformer KVA rating 6) transformer full load amps
how to setting Load amps tripping time and extra settings for load Transformer protection relay with RMU panel using C&S model relay..?
In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
how to revers the direction of single phase motor
How much voltage we need to apply in 33kv cable during hipot test of cable
