What's New at HV Power

New TCG 02-E from Tekron
For the ultimate reliability, Tekron now make available the TCG 02-E time clock. Built on the extremely reliable TCG 01, the TCG 02-E features: Additional redundancy with dual power supply option Master/Slave function allowing two units to provide a fully redundant swappable system Remote engineering access via TCP/IP IRIG-B, pulse outputs, serial outputs, NTP/SNTP and PTP output options Power supplies are the most common point of failure for most equipment. Therefore the TCG 02-E features an option for two independent internal power supplies (100-300Vdc / 85-264Vac). With this option, separate IEC320 power supply inputs are provided at the rear of the unit, allowing the TCG 02-E to be connected to independent sources. Should one source (or one internal power supply) fail, the TCG 02-E will continue to operate from the other. The TCG 02-E supports being mounted together with a second unit, and interconnecting to one GPS antenna to provide a fully redundant system. The TCG 02-E features many of the specifications and features of the TCG 01, but with expanded outputs similar to the TCG 01 with multiport hub option. TCG 02-E data sheet Question: How does the TCG 02-E compare to the recently introduced TCG 08? Answer: The TCG 02-E provides one GPS clock with the intention of a fully redundant system being constructed using two separate units. The TCG 08 features the redundancy of two clocks, but within the same enclosure.
New Variant of REYROLLE Argus-C Relay
The 7SR1102 Overcurrent and earth fault protection relay has been developed to enhance the Argus family of compact relays by providing an overcurrent function package suitable for basic feeder applications. Communication access to the relay is via a front USB port for local PC connection for programming, and a rear electrical RS485 port is provided for SCADA. This new Argus Relay is aimed at reducing engineering time by reducing complexity.

HV Power Training Courses
HV Power run various training courses throughout the year. Our first training course for the year has been successfully run, but we will be doing others throughout the year. Provisional dates for other training courses in 2010 include: 6 May - Introduction to DIGSI and SIPROTEC Relays All courses will be held in Auckland. For further information, to book a place on one of these courses, or to inquire about training in your area, please contact Vladimir Brijackek.
