location : PD2
defect : motor viper extraction cannot stop
location : black start diesel generator (BSDG)
- check battery : 24V DC battery for start up
- use hydrometer to check water level = 1.28
- use multimeter to check the voltage = 12.30V
- the battery have to check because it will be use as back up when do the blackout test this Sunday (9 May)- battery: back up for NGR (neutral ground resistor)
- EDG (emergency diesel generator) : to energize station essential board and provide emergency AC supply in case of normal AC power supply failure.
6.6kV --> EDG --> step down 415V --> auxilary Tx
