Scaling Example 3: SNAP-AIPM-3 without PT
Leave Actual values at their defaults for all points, and leave
Lower Scaled values at 0. Calculate Upper Scaled values for
points as follows:
Points 0, 4, 8: Always 300 volts
and 300 VAC. (For line voltage over 300 V, use Example 2.)
Points 1, 5, 9: 5* (CT primary / CT secondary)
Points 2, 6, 10: Upper Scaled for voltage * Upper Scaled for
current (ex. Upper Scaled for pt 0 * Upper Scaled for pt 1)
Points 3, 7, 11: Upper Scaled for voltage * Upper Scaled for
current
Points 12, 13: 3 * Upper Scaled for voltage * Upper Scaled
for current
Example
Voltage: 240 VAC (no potential transformer required)
Current: 180 amps (requires CT primary of 200).
CT has a secondary of 5 A.
So to calculate points 1, 5, 9: 5 * (200/5) = 200
...points 2, 6, 10, 3, 7, 11: 300 * 200 = 60,000
...points 12, 13: 3 * 300 * 200 = 180,000
1 IMPORTANT—Voltage change: Older SNAP-AIPM-3
modules used 0–250 volts and 0–10 amps. Before wiring or
scaling, check the printed information on the module to make
sure you are using the correct voltage and current. Contact
Product Support to exchange older modules.

Scaling Example 4: SNAP-AIPM-3 with PT
For line voltage higher than 300 VAC
potential transformer (PT) must be used.
Leave Actual values at their defaults for all points, and leave
Lower Scaled at 0. Calculate Upper Scaled values for points as
follows:
Points 0, 4, 8: 300 * PT ratio
Points 1, 5, 9: 5* (CT primary / CT secondary)
Points 2, 6, 10: Upper Scaled for voltage * Upper Scaled for
current (ex. Upper Scaled for pt 0 * Upper Scaled for pt 1)
Points 3, 7, 11: Upper Scaled for voltage * Upper Scaled for
current
Points 12, 13: 3 * Upper Scaled for voltage * Upper Scaled
for current
Example
Voltage: 480 VAC (requires potential transformer).
PT ratio is 2:1
Current: 350 amps (Requires CT primary of 400. CT has a
secondary of 5 A.
So to calculate points 0, 4, 8: 300 * 2 = 600
...points 1, 5, 9: 5 * (400/5) = 400
...points 2, 6, 10, 3, 7, 11: 600 * 400 = 240,000
...points 12, 13: 3 * 600 * 400 = 720,000
