Check out the article on Powerco and their use of the the Horstmann Smart Navigator 2.0 fault indicators, found in the latest T&D magazine. The intelligent overhead line monitoring sensor is providing real-time network visibility and directional fault indication to assist with faster power restorations for their New Zealand customers.
With the Smart Navigator 2.0 you can quickly locate the fault and have it displayed locally onsite and remotely in the control room. Measurements are taken of the current, voltage, load flow direction and conductor temperature – continuously. With remote parameterisation, you can react easily and quickly to changes in the network topology.
The Smart Navigator 2.0 is recommended for use in all branches of an outgoing feeder, in riser poles at the transition from the underground cable network to overhead (UGOH) and in inaccessible or hard-to-reach areas on both sides. It is impressive wherever it is used, particularly due to its very bright LED display. Designed to give a 360° view, it enables you to detect faults from a great distance – making it much easier to search for the location of a disruption, particularly in adverse conditions.
Another great installation of our equipment by the team at Essential Energy, who upgraded there 22kV Ripple Control Plant at Bourke in the far north-west of New South Wales on the south bank of the Darling River. This will ensure reliable control of peak load for many more years to come.
The principal contractor for the Southwest Metro area is Laing O'rourke and John Holland while Quickway has been engaged to deliver the power enabling works project which involves the below.
Excavation of trenches and installation of conduits to hold new cables
Backfilling trenches and resurfacing the areas
Joint bay construction and installation works
Cabling works, customer kiosks
Quickway are currently in the process of installing mechanical press seals to seal their 200mm HV conduits in the jointing bays with the main issue at hand been water ingress. Contractors on site informed us they were instructed to initially use a chemical seal but the feedback given was that this was a very messy and time consuming install. It also failed to adequately seal the area between the cable and the conduit. (A temporary but not permanent solution). By using Hauff Technik seals there is a cost saving in labour.
Hauff-Technik mechanical press seals were specified in to meet the requirements of the project. With the ability to install the seals after cables had been run and the versatility to seal different sized cables & conduits Hauff-Technik’s HSD seals were chosen. With the seal been able to withstand water pressure of 2.5bar it was a perfect fit for the issue at hand.
Quickway found installation to be extremely quick and straight forward. If these pits need to be accessed in the future there will be zero maintenance involved, and by Quickway taking initiative to come up with an effective sealing solution there will be massive cost savings for the project.
