Title: Solar Protection Relay - Ausgrid Witness Testing - BCJ Controls


1
Supporting Solar InstallerSolar Protection Relay
  • At BCJ Controls we make it as easy as possible
    for you to get your 30kW solar installation over
    the line.

2
Connection Application
  • Need help with the 30kW grid connection
    application? Have a look at our application
    guides below. More to be added shortly...

Drawings
  • We can provide a Single Line Diagram as part of
    your Connection Application (to get one send us
    an email at contact_at_bcjcontrols.com.au).

Supply Authority (DNSP) Liaison Services
  • Application handling and negotiations can be a
    chore. At BCJ we have people who are former
    utility workers, so we are happy to relieve you
    of this burden and deal with your supply
    authority ourselves.
  • The Distribution Network Service Provider (DSNP)
    is quite often the gatekeeper, and major choke
    point, for getting your project completed.
    Application handling and negotiations can be a
    chore at best, a nightmare at worst.

Supply Authority (DNSP) Liaison Services
  • At BCJ we have people who are experienced in this
    regard, so we are happy to relieve you of this
    burden and deal with your supply authority
    ourselves.
  • Our design team can help you with AutoCAD issues.
    If you need single-line diagrams, switchboard
    design, AC/DC PV systems, control and protection
    systems design carried out please get in touch
    with us.

Ausgrid Witness Testing
  • Customers with installations within the Ausgrid
    service area are required to carry out witness
    testing of their installations. Checks on the
    protection relays and inverters will need to be
    carried out in situ, in conjunction with an
    Ausgrid employee on the same day. Ausgrid witness
    testing is considered by Ausgrid to be
    commissioning works, carried out under their
    standards NS194 and NS194A.
  • A Witness Tester will need to perform several
    electrical tests on the relay. These include
    over/under-voltage, over/under-frequency, phase
    shift, rate of change of frequency (ROCOF). These
    tests are all concerned with what happens during
    a Loss-of-Mains (LoM) event, and its potential
    impact on the network. Short-circuit protection
    (overcurrent) is not considered a part of this
    testing regimen, and should be carried out at a
    different time.

Ausgrid Witness Testing
  • An Ausgrid person will be present, as your
    installation will be connected to the network
    during the final operational checks. They will
    want to see that the primary network protection
    operates as intended, as well as look at the
    relevant test plans and results. They will want
    to see that what has been built and tested
    matches the agreed design. They may ask for
    copies of results and settings to be supplied as
    an official record.
  • The Tester will also carry out checks on the
    Inverter, and supply Ausgrid with a copy of the
    Inverter settings (generally with a screenshot
    direct from the Inverter software).

Ausgrid Witness Testing
  • Organizing both a Witness Tester and Ausgrid for
    the same day can be a challenge, so you will need
    to be flexible in your choice of date and time.
    At BCJ Controls we can carry out the testing, and
    make the arrangements with Ausgrid for you
    saving you a good deal of hassle! We can cover
    the entire Ausgrid service area, including Sydney
    Metro, Central Coast, Newcastle, Hunter Valley,
    and Muswellbrook regions.

BCJ Controls
  • At BCJ Controls we offer Ausgrid Witness Testing
    as a service to commercial solar installers who
    want to get their solar installation over the
    mark with Ausgrid. Generally we
    coordinate Ausgrid and our tester so that there
    is someone to test the relay in front of the
    Ausgrid representative. Give us a call on 02 9534
    8465 to arrange.
