HV Power Product RangeHV Power supplies proven, advanced products from around the world. Products include:
Within a supplier's product range, and occasionally between suppliers, there are often different solutions to a problem. We have many years experience in assisting companies find the best products for their particular application. We can tell you what works best, what local technical support is available and how to implement the most cost-effective solution for your application - just give us a call.
Protection relaysTo offer our customers the best product for a specific application, we offer IED’s from Siemens (SIPROTEC and REYROLLE brands) and RMS:
Transformer voltage regulators and temperature controlsWe recommend the REG-D and REG-DA series of voltage regulators for the control of transformer tap changers. They are New Zealand’s most popular voltage regulators, and are in use on all major NZ utility networks. While there are other solutions, Reg-D/DA is the benchmark in reliability and performance. 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.
Voltage detectors and safety systemsTo allow the safe verification that switchgear and lines are dead, we offer a range of DEHN contact and non-contact voltage detectors. Hot sticks and other tools are available for switching and live line work. Products include:
Power quality instruments and revenue meteringPower quality – field tools Power quality- permanently installed Note that our Nexus revenue meters and Shark 200 check meters also feature basic power quality functionality. Network collapse prediction Revenue metering Check metering Energy management
Substation automationSubstation management systems, bay controllers and data concentrators are offered as part of the Siemens product line. With Siemens leading the industry on implementation of IEC 61850 IED solutions, HV Power have a substantial expertise in the practical implementation of this ground breaking industry technology. HV Power can provide expertise to integrate connectivity of multi-vendor IEC 61850 and legacy protocol equipment. 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.
Time synchronisationWe provide GPS clocks (time code generators) for the synchronisation of IED’s using IRIG or NTP connections. We also offer programmable outputs for the synchronisation of equipment requiring one pulse per second (1PPS) or other types. Tekron International are the world leader in timing applications for the substation environment. We also offer dedicated NTP (Network Time Protocol) servers for the synchronisation of computer network equipment, such as SCADA master stations.
Hardened EthernetWe offer industrial networking solutions for the factory automation, power utility, telecommunications and temperature-uncontrolled, outdoor locations. Electrically hardened and offering extended temperature ranges, these products are suitable for network-critical applications. 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:
Remote monitoringCompact, low cost RTU ‘telemetry boxes’ are offered for the monitoring of network assets that could not be economically justified using traditional SCADA systems. Examples of applications include:
Surge and lightning protection productsTo protect mains powered equipment and data circuits from the damaging effects of lightning and switching surges, HV Power offers a wide range of DEHN surge protection products, including:
Other productsWe offer a wide range of solutions including:
