CP DB1 - Transformer Discharge Box
Accessory for CPC 100
CPC 100 with CP DB1 for faster discharging
The CP DB1 transformer discharge box facilitates fast 
discharging of power transformers after a test of the 
winding resistance. 
A transformer must be discharged whenever the DC 
measurement of one phase has been completed. 
Thus you can save a lot of time by measuring with the 
CP DB1.
In 6 A operating mode the CP DB1 speeds up the discharging process by a factor of four, in 100 A operating 
mode by a factor of ten.
The CP DB1 is a CPC 100 accessory for testing with the 
RWinding and TRTapCheck (for OLTC) test cards.
