The OMICRON CP SB1 Switch Box for 3 Phase Power Transformers is an accessory for the CPC 100
and simplifies measurement of three-phase power transformers. The transformer ratio and winding resistance are automatically measured in all three phases (in sequence) in all tap changer positions. The measurement results are recorded by the CPC 100 and can be analyzed with the accompanying software package.
Multiplexes the CPC 100 outputs to all phases of a power transformer and vice versa
Quickly discharges the transformer between measurements
Operates the tap changer, so measurements can be performed without the need for user interaction
For every tap changer position the transformer ratio and winding resistance can be measured
