What's New at HV Power

The "Web Server" is back! Electro Industries Shark 200 Multifunctional Meter again features a web server function. Units purchased (or upgraded) with the Ethernet interface feature an on-board web server that provides a graphical view of meter information. You don't need to bother with SCADA mapping or proprietary software; simply type the IP address into your web browser to see the meter information on line.

The web server feature was supplied in the Shark 200 up to a couple of years ago, when it was removed due to legal action by a competitor. This has now been resolved and the functionality returned to the product.

Yes, you can… use DNP-IP with REG-D/DA voltage regulators. For years customers have used a serial protocol card for SCADA communication to REG-D/DA . Now alternative protocol cards offer support for both Ethernet & serial based protocols. The “XW96” order option allows users to standardise on one version of REG-D/DA hardware, but also support sites with serial or Ethernet interfaces, thus effectively supporting legacy and future protocols. By loading the appropriate protocol files, serial DNP, DNP-IP or IEC 61850 can be supported. Choices of interfaces include copper and Fibre .

While the XW96 is best applied to new REG-D/DAs, there are many solutions for existing REG-D/DA’s – even for those without protocol cards. For example, REG-PED is a standalone version of the protocol card (also available as an add-on card for REG-D enclosures) which can connect to a REG-D/DA COM2 interface. Using the E-LAN interface, the REG-PED can access the other connected REG-D/DA units and provide SCADA visibility to those points too. This allows multiple REG-D/DA’s to be connected to SCADA via one REG-PED. This configuration can operate with REG-D/DA’s that were installed without protocol cards, or where older protocols need to be upgraded (e.g. to DNP-IP or IEC 61850).

There are a host of options available. Contact us to discuss your application so we can engineer a solution to your needs.

This time last year we provided an overview of the range of Pilot Wire Differential Relays offered by HV Power. With the upcoming release of the SIPROTEC 7SD80, it is appropriate to share some advanced information, and to explain where the 7SD80 will fit into our offering.

The new 7SD80 is based on the popular compact 7SJ80. The 7SD80 specifically addresses line differential applications for medium voltage lines and cables. What's important is the relay can be ordered with copper pilot wire protection data interface, and/or fibre. When two protection data interfaces are fitted, they operate in a parallel redundant mode. Alternatively, the combination allows the relay to be implemented with copper pilots, and then the fibre interface can be used if the pilot circuit is upgraded.

Putting the 7SD80 into perspective, HV Power now has an even wider range of solutions, covering virtually every line differential protection application - from simple Solkor-R/Rf Pilot wire through to sophisticated Multi-terminal transmission line protection.

Internationally, the conversion of networks to resonant earthing is increasingly being undertaken to improve network reliability (improve SAIDI/SAIFI). These systems have been used for many decades in Europe with great success. Now HV Power offers a dependable solution for improved reliability of 11kV and 33kV networks, based on the cost effective Petersen coil. Coupled with modern current injection and advanced earth-fault detection and location techniques, HV Power’s turnkey system is both cost effective and powerful.

HV Power has secured the rights of two major international companies to allow us to offer our customers this integrated and improved solution. EGE, a market leader in Europe and international supplier of Petersen coils, together with controllers and earth-fault detection products from our long standing supplier A.Eberle, are the basis for a turnkey solution. A.Eberle and EGE products are a proven and effective combination, used together in many countries around the world. These two suppliers have worked together to further improve the technology, such as the modern current injection techniques for improved control and earth-fault detection.

SCADA interface for Petersen coil control and earth-fault detection is available for DNP (serial and IP) and IEC 61850 SCADA systems, to suit New Zealand utilities.

The GarrettCom Magnum 10ETS Ethernet Terminal Server provides serial-to-Ethernet conversion. Serial devices are still widely deployed in our industry. However, substation communication networks are increasingly becoming IP-based. The 10ETS provides a managed device capable of interfacing between these two technologies. This allows your serial-connected IEDs to continue to perform for many years ahead, while now being connected into a modern and reliable industrial IP network.

The Magnum 10ETS Ethernet Terminal Server features modular ports, allowing it to support:

• 2-32 serial ports (up to 32 ports with RJ45 connection, or 16 ports with DB9 connectors)
• 2-8 Ethernet ports (mixture of 10/100 copper, 100Fx(MM) for 100Fx(SM))
• Refer to the configuration guide for permissible combinations

Like the 10KT, the 10ETS is fully IEC 61850-3 substation-hardened, managed and features dual hot-swappable power supplies, all in an industrial-grade 1U rack-mount. The 10ETS has two power supply slots, each of which can be hot-swapped (without removing any power supply wiring!). The 10ETS design permits the dual power supplies to be of different input voltage ranges, thus giving users extra reliability by allowing the switch to be powered from, for example, a 48 Vdc power source and a 110 Vdc power source.
