    Our regulators support simple voltage regulation - on single transformer applications through to the complex control of multiple parallel transformers. Temperature controls can be integrated into the Reg-D and Reg-DA regulators when you specify the TMM option.

    In New Zealand and Australia, there is an increasing demand to reduce the number of supply interruptions experienced by consumers. For Network owners there is also a statutory requirement to meet minimum SAIDI and CAIDI standards. One way of substantially improving these is to be able to operate the network safely and in continued operation in the presence of earth faults.

    Energy management
    Software systems for complete and comprehensive energy management/reporting.

    While we recommend the use of IEC 61850 where ever possible due to its efficiency and power, we are also well versed in the implementation of IEC 103, DNP3 (serial and Ethernet) and web based systems.

    We offer the latest in support of various optical fibre circuits, 10baseT, 100baseT and Gigabit circuits (fibre and copper). Power-over-Ethernet (POE), DNP, DNPi, IEC 61850 and many other protocols supported.

    Many of our customers are electrical utilities, wanting to automate, simplify and make more reliable their IED/SCADA network. While they want to take advantage of new features such as IED’s with built in web pages etc, they do not want to become experts in network topology and protocols. Give us a call and we can help with:

    • Managed Ethernet switches
    • Unmanaged Ethernet switches/hubs
    • Routers
    • Serial communications (Device servers, Terminal servers etc)
    • Media converters
    • Cyber security
    • Monitoring of status of remote pole mounted auto-reclosers
    • Monitoring of cable fault and overhead Fault Position Indicators (FPIs)
    • Monitoring of running time, fuel level and location of portable generator sets
    • Remote monitoring of tank level (water, sewerage, fuel etc)
    • Remote control/monitoring of co-generation equipment
    • Alarm monitoring (as a redundant back-up system to traditional SCADA)
    • Provision of third party access to selected site information, eliminating need to open access to network SCADA system
    • Voltage detectors (3-420 kV, contact and non-contact, indoor and outdoor varieties)
    • Phase comparators
    • Insulated operating and switching rods
    • Earthing sticks
    • Live cleaning tools
    • Low voltage AC surge protection products (<1 kV)
    • Low voltage data surge protection products
    • Protection for photovoltaic solar cells
    • Intrinsically safe surge protection
    • Isolating spark gaps and equipotential bonding products

    We offer a wide range of solutions including:
