BPLC Introduction

Pilot wire used for transmission line protection is failing

17% failure rate according to an SEL study

Copper based wire is aging and deteriorating due to corrosion

Copper theft is an increasing problem Phone companies are phasing out the service

Many utilities lease the pilot wire lines


erna ves are er or conven ona

Today only 9% of US substations are connected by fiber

Replacing pilot wire with fiber is very expensive and requires along deployment process

BPLC costs 10% of fiber and deploys in days compared to weeks

Amperions BPLC technology was developed jointly with AEPto solve this problem

Available now - no need to wait for fiber

BPLC Enables Better Protection

BPLC can be used to connect substations over transmission,sub-transmission and distribution lines

Transmission protection is implemented today with analog

relays using POTT and DCB schemes Protection schemes can be enhanced with the new generation of digital relays

that support multiple options including current differential

At the Distribution level coordination will become more difficult with more


distributed generation and multiple terminal points Current differential is the most accurate and reliable

protection scheme But requires a reliable and fast communications channel

Fiber is too costly for lower voltage substations and notalways available BPLC is the next generation PLC and provides a ready-to-deploy cost effective

alternative


23/25

Summary

Over 622,000 transmission miles in the US require an investment of $36Band decades to deploy fiber to every substation

67% of the US transmission lines are at 138kV or below (sub-transmissioncategory) and are potential candidates for the BPLC technology

Deploying BPLC instead of fiber costs less than 10% and can beaccomplished in a much shorter timeframe

Substation automation requires a reliable broadband communications


c anne to ac au cr t ca ata n rea t me

BPLC can be used to enable station retrofit projects that include upgradingsubstation equipment and supporting new smart grid applications

BPLC can also be used on distribution lines enabling accurate and costeffective current differential protection over short distances

Initial applications for BPLC will be pilot wire replacements, leased linereplacements, PLC upgrades, fiber extensions and fiber redundancy and

back up options
