Our second course for 2010 is aimed at providing a basic foundation in the operation of DIGSI software for the programming of SIPROTEC relays. This course will be predominately "hands-on" to provide the maximum opportunity for attendees to learn practical skills for application, setup, operation and testing of Siemens SIPROTEC protection relays.

This one day course, to be held at our Auckland facility, will be limited to 10 participants.

Please register with Vladimir Brijacek (ph 09 304 1685). Course cost is $550+GST.

For further details, see our course invitation.

The new GarrettCom Magnum™ DX940 is a versatile and configurable Industrial Router. The DX940 combines WAN access, IP routing, Ethernet switching, Serial-to-IP terminal services and advanced security features in a small-footprint industrial package. It is ideal for small and midsized remote sites, such as electrical substations, renewable power generation facilities and transportation control pedestals. With 3G wireless capability, the DX940 can provide secure access even where copper or fibre connection is too difficult or too expensive to deploy. Configurable port options for 10/100 and 1Gb copper and fibre media are also available for the DX940.

Optional Serial ports enable Serial-IP terminal services via RS232, RS485 and RS422 serial interfaces for protocols such as DNP, telnet and Modbus, including Modbus-ASCII/RTU to Modbus-TCP interworking.

The DX940 is purpose-built for extremely harsh environments, such as a factory machine shop floor or power utility substations. The DX940 meets IEEE 1613 and IEC 61850-3 specifications for EMI/ESD protection and operates at extremes of temperature -40 to +85° C without open vent holes or fans. Robust metal enclosure is standard and conformal coating of PCB for protection against moisture and corrosion is available.

To ensure that standard practices are being applied across all your network project teams, HV Power Services offers a range of value–added IED services. We can help you speed up projects and standardise implementations. Maximise effectiveness of your technical staff by having HV Power Services take care of the non-time critical but none the less important items that staff don’t really need to know or want to know about. We believe an experienced person outside of your own organisation can often see the tree from the woods when it comes to : Acceptance tests for protection devices Initialisation and application of settings Functional tests as per the settings and the design SCADA points test Subsystem tests: relays, communication schemes, complex protections (BZ and CBF) and interlocking (including goose messaging and SCADA points test up to the control room)

Our experienced HV Power Services staff are familiar with the latest IED technology.

We also offer a range of short term engineer-to-contract services to help you overcome labour or skill short-ages. We can create a scope-of-works specific to your needs. Contact Vladimir Brijacek (ph 09 304 1685) to find our more.

DEHN PHE Voltage Detectors are designed to verify safe isolation from supply voltages at work sites in accordance with the stringent International Standard IEC 61243-1. Available as fixed voltage: 11 kV, 33 kV, 66 kV or 110 kV units, with some models offering dual range. The majority of DEHN’s range are contact type detectors with a variety of electrode ends available. DEHN Voltage detectors are classified into 2 categories, based on the requirement to operate correctly even in the presence/influence of interference voltages. A category ‘L’ detector uses a short test prod and is designed for use on overhead lines. Category ‘S’ detectors have a long test prod – using an extension for the contact electrode - to keep the detector back from the test object – to eliminate the influences of any interference fields, such as in switch panels. DEHN voltage detectors provide both audible and visual indication.

DEHN have worked closely with switchgear manufacturers to ensure the operation of their detectors is in strict compliance with prescribed Safety Rules. To find why power utility field staff around the world rely on DEHN Voltage Detectors see for yourself.

For optimum protection, monitoring the temperature of transformers, motors and generators is an essential protection function. The Siemens 7XV5662 series of Temperature Monitoring Boxes are designed for such applications and operate with a variety of SIPROTEC relays. Siemens have just released an application document showing how simply this measurement capability can be implemented. Download the application document.

The Temperature Monitoring Box currently supports

• 7SK80 - Motor Protection Relay
• 7UM62 - Multifunction Generator, motor and transformer protection relay
• 7SJ602, 7SJ61/62/63/64 - Overcurrent /feeder Protection Relays
• 7UT612, 7UT613 & 7UT63x - Differential Protection Relays

When you need simple TRIP and CLOSE controls for circuit breakers to be highly visible, the RMS 1X50 Trip & Close Module is the answer. No longer do you have to find the trip and close buttons hidden amongst the other protection relay controls. No longer do you need to protect the operation of breakers by four digit passwords, instead 1X50 uses the tried and trusted manual lockable cover.

The 1X50 can be panel or rack mounted. Heavy duty push buttons are employed for the CB TRIP & CLOSE functions with two LED’s provided for CB status indication. An additional status input is available to provide an LED indication when the CB close spring is charged. A lamp test button is also available.

Reduction of system frequency is often an early indicator of impending system voltage collapse. RMS’s 2H34 Relay is a four stage under/over frequency relay with rate-of-change-of-frequency detection (dF/dt). Also included is under-voltage blocking and separate under-voltage and over-voltage alarms. This relay is especially suited for load shedding applications, including small generator protection. RMS’s 2H34 has been upgraded to become 2H34S and now boasts: Front panel USB interface for setup Improved LED backlighting Improved measurement stability Wider range of input-voltages

This relay offers four stages of adjustable frequency pick-up & drop-out points. Each frequency set point can be set for under-frequency or over-frequency operation & has an independent time delay driving an output relay. An under-voltage lockout is used to disable the four frequency outputs when the voltage falls below a preset level. Each of the four setting stages can have a rate-of-change-of-frequency (ROCOF) element with an independent time delay. The ROCOF element is available to operate as an AND or an OR logic function with the frequency element (ANSI 81 & 81R elements).
