Automated Streetlight and Sub-Meter Testing
........................................
OVERVIEW
Sub-meters and streetlight meters are becoming major topics of interest in the electric utility industry. As these new meter types approach revenue grade, utilities are looking for an effective way to test them in high volume, while maintaining the NIST traceability required if they are to be used for billing. To maximize meter shop efficiency, utilities need a way to test these meters using their current testing processes. The RADIAN Multi-Channel Pulse Comparator is here to solve this challenge.
The Multi-channel Pulse Comparator is designed for use with RADIAN's WECO 4000 series test boards. Each comparator has 16 pulse inputs. Each WECO 4000 series test board can interface with up to four comparators simultaneously.
The WECO 4000 sources voltage and current to a group of up to 16 meters per comparator. The pulse output from each meter is connected to a comparator channel. Meter pulses are compared with reference pulses from the RADIAN standard housed within the WECO 4000 test board to determine meter accuracies. This flexible approach allows the Multi-Channel Pulse Comparator to be moved and operated from any WECO 4000 series test board.
