Functional Testing - How to Cope With Ever Changing Needs & Requirements

  1. 1. 10/02/2012 Slide 1 Functional Testing How to Cope with Ever Changing Needs & Requirements Notes from the Shop Prepared by Tom Lawton,TESCO for the Spring ECNE Engineering & Operations Conference 2016
  2. 2. Session Objectives • Discuss the differences between functional and accuracy testing • Discuss the types of functional testing required in a post- AMI world • Discuss the need for functional testing as well as Certification or FAT testing (first article testing) Session ObjectivesSession Objectives
  3. 3. Types of Meter Testing • New meters have many tests specified in ANSI C12.1 and C12.20, usually performed by the meter vendors. • With In-service meters, mainly meter consumption accuracy – Maybe Full Load, Light Load, Weighted Average Accuracy – In the Meter Shop (periodic in service testing requirements) – In the Field (customer inquiries & complaints) • With AMI/Smart Grid, must consider meter device functional testing for in-service. Types of Meter Testing
  4. 4. Impact of AMI & AMR Test an installation and system and not just a meter! Test programs for AMR & AMI systems need to involve testing and checking the meter performance as well as checking and testing the installation. This more extensive test check list needs to be done especially for the higher revenue C&I customers. Impact of AMI and AMR on Meter Testing
  5. 5. Impact of AMI Devices • New concept of what is a meter…includes everything under the cover. • AMI communications modules and service disconnect switches. • Need to apply sampling and testing requirements to these devices when part of the AMI meter. Impact of AMI
  6. 6. Categories Of Meter Testing • New Meters – Testing in the Meter Shop • In Service – Testing in the Meter Shop for State sampling requirements – Testing in the field for customer inquiries or complaints • Retirement – Testing in the Meter Shop Traditional Categories of Meter Testing
  7. 7. • Inspection • Error Reporting/Clearing • Clear/Reset • Meter Reprogramming • Program Verification • Disconnect Testing • Firmware Updates • Security Updates • Password Updates and Verification • Battery Replacement AMI Meter Testing
  8. 8. • Firmware Updates • Disconnect Testing • Meter Association Confirmation • Network Status Updates • Security Updates • Communication Interval Verification and Configuration • Communication Verification • Real Time Clock synchronization • Zigbee • Alarms (Verification and Programming) • Lat/Long (Verification and Configuration) AMI Network Testing
  9. 9. • As a part of Standard Testing • As a check for “new meters” • As a check of an installation When do we do this testing?
