PZ1000 distance protection has 4 zoMHO characteristic firing and / or sadditional square phase-phase faultsTeleprotection and schemes, monito(Per pole) and other functions, comimportance of high level.

DESCRIPTION

PZ1000 teams are numerical distance protections,particularly suitable for primary protection of linessingle or double overhead transmission and subtransmission(AT and MT).

Its advanced design algorithms multiprocessor with rapidtwo signal processing and ensure prompt actionmaintaining safe and high reliability featuresservices necessary for the management of networks of trans-mission and distribution.

The team has a serial port PZ1000 front communicationand may have up to two rear ports that allow:

Connect to an integrated system of protection and control.

Access to status information, historical data and adjustedtees, locally, centrally or remotelyvia telephone.

It also includes a third port dedicated rear communicationed to teleprotection, which allows direct connection between twoprotections.

I Directional lock: DCB

I Directional release: DCUB

Additional schemes:

I ECO (permits)
