APPLICATIONS INFORMATION
longitudinal balance
Figure 18 shows a three terminal TISP with its equivalent "delta" capacitance Each capacitance, CTG , CRG
and CTR , is the true terminal pair capacitance measured with a three terminal or guarded capacitance
bridge. If wire R is biased at a larger potential than wire T then CTG > CRG . Capacitance CTG is equivalent to
a capacitance of CRG in parallel with the capacitive difference of (CTG - CRG ). The line capacitive unbalance
is due to (CTG - CRG ) and the capacitance shunting the line is CTR + CRG/2 .
Figure 18.
All capacitance measurements in this data sheet are three terminal guarded to allow the designer to
accurately assess capacitive unbalance effects. Simple two terminal capacitance meters (unguarded third
terminal) give false readings as the shunt capacitance via the third terminal is included.
