eMeter Corporate Logo
To ensure the integrity of the eMeter brand it is necessary to understand how to use
the logos.
Minimum Clear Area
A minimum clear area has been created around each logo. This area should always be
kept free of any graphic elements and/or messages. The gray lines in these illustrations
show how the minimum clear area is calculated. In all cases, an area equal to the cap
height of eMeter “r” must remain clear on all sides of the logo. The gray bars in these
illustrations indicate the visual height, width, vertical center and horizontal center of
the logo.

Centerpoint Load Calculation
Manual: 2 People analyze 30 transformers in 2 weeks
eMeter Analytics: Automatically analyze 400,000 transformers in 5
minutes
Power Factor
• Required since kVa is not recorded on a 15 minute basis
• Created only for non-residential customers
• Validation check performed and recorded to “qualify” each power factor
• There are approximately 5 – 8 power factors calculated by each meter for each month
Interval kVa Calculation
• Calculated for each 15 minute interval by ESIID
• Only uses valid power factors for non-residential and .9 for residential
• Validation check performed and recorded to “qualify” each load calculation
Transformer Aggregation
• Aggregated and stored by transformer over the last hour
• Validation check performed and recorded to determine if all expected intervals utilized and also if any of the intervals failed validation
