Connection Examples

 

The input connections shown below are only examples. 
Direct connection without the use of current or voltage 
transformers can be made to the SIMEAS P as long as the 
maximum allowable  current and voltage ratings of the 
SIMEAS P are not exceeded. 

The voltage transformers can be connected in wye or open-
delta configurations. 

All inputs not required for measurements should remain 
disconnected. 
 
 

Attention: 
 
The single ground connection of the instrument transformers 
is shown for illustration only. 
Actual grounds must be installed directly at each instrument 
transformer.
