Measurements of a Power Source:Connection
Method 1 – Ext CT
Figure 15. Measuring a Source Using a CT, Method 1
Configure the channel as follows –
•
This connection method is suitable for most external transducer
applications.
•
At high frequencies, the wiring length between the source and the current
and voltage measurement points should be kept as short as possible to
avoid inductive and capacitive losses causing inaccuracies.
•
Optionally, set
Wiring Impedance
to (W1 + W2) ohms. Include all wiring
resistances between the source and the points at which the voltage is
measured in the entered value for wiring impedance.
•
Set
V Burden Compensation
to
YES
.
•
If the current measurement terminals of the 2801 or the wire through the
CT (but not both) are reversed then set
Reverse Current
to
YES
,
otherwise set to
NO
.
•
If the voltage measurement terminals are reversed, then set
Reverse
Voltage
to
YES
, otherwise set to
NO
.
•
If using a current output CT then use the A terminals, otherwise use the T
connector, of the 2801. If using a current output CT and using the
internal line switch of the 2801, then take care to reduce the length of the
common wiring of the two signals to the A+ terminal of the 2801.
