SNAP Power Monitoring Modules
Scaling Example 1: SNAP-AIPM 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:
Point 0: Always 250 volts for line voltage between 85 and 250
VAC. (For line voltage over 250 V, use Example 2.)
Point 1: 10* (CT primary / CT secondary)
Point 2: Upper Scaled for pt 0 (voltage)* Upper Scaled for pt 1
(current)
Point 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; the module accommodates 10 A.
So to calculate point 1: 10 * (200/5) = 400
...points 2 and 3: 250 * 400 = 100,000

Scaling Example 2: SNAP-AIPM with PT
For line voltage higher than 250 VAC, a step-down
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:
Point 0: 250 * PT ratio
Point 1: 10* (CT primary / CT secondary)
Point 2: Upper Scaled for pt 0 (voltage)* Upper Scaled for pt 1
(current)
Point 3: Upper Scaled for voltage * Upper Scaled for current
Example
Voltage: 277 VAC (requires potential transformer).
PT ratio is 2:1
Current: 350 amps (Requires CT primary of 400. CT has a
secondary of 5 A; the module accommodates 10 A.
So to calculate point 0: 250 * 2 = 500
...point 1: 10 * (400/5) = 800
...points 2 and 3: 500 * 800 = 400,000
