What's New at HV Power

For the voltage regulation of three winding transformers, a special feature is available on REG-D and REG-DA devices. This “three winding” function enables voltage regulation on the selected winding and “supervises” the other. A range of automation functions are available to select which winding is to be regulated and which one is to be supervised.

The three winding function can also be used for other applications such as regulating interconnecting transformers where reverse power flow can occur. With increasing distributed generation being added to the network, reverse power flow is becoming more of an issue for non transmission customers. The REG-D/DA can take care of these applications.

To improve the operational reliability of digital inputs on some IEDs and RTU’s, RMS have released their Active Burden Modules (ABM’s). The ABMs are installed prior to the binary inputs on an IED to improve the electrical transient and noise immunity, reducing the possibility of nuisance/false activations or maloperation. The ABM’s work by providing a temporary increased burden to the input signal – to dampen out noise.

The ABMZ is a special version that provides a minimum voltage pick-up threshold. If you have IED’s with very sensitive or low voltage pick-ups or so-called universal range inputs, the ABMZ can be used to provide a definite voltage switching threshold level of 30V, 80V or 150V.

By installing the ABMZ at the IED/RTU inputs, you can ensure a guaranteed minimum voltage pick-up to your IED/RTU. This is ideal for IED/RTU’s where coupled/induced noise is causing false operations.

The ABM and ABMZ are available in a DIN rail mount enclosure. The ADM can also be supplied in a package that can be hung off the back of the relay terminals – ideal for retrofits!

Also available from HV Power is the “Pelican” case, rugged shipping container. Although the Pelican case is larger and heavier than the A.Eberle case, it’s ideal for where a very strong transportation container is required, such as when the PQ Box-100 is sent as unaccompanied freight via courier, or where watertight storage is required.

The existing 100 mA to 22A mini clamps (111.7002 [3 clamps] & 111.7003 [4 clamps]) are being replaced by switchable clamps (111.7015) with the range:

• 100 mA to 22 A
• 1 A to 200 A

The Auxiliary input (power supply) range for all new PQ-Box 100’s will now be 110-440 Vac or 220 Vdc. This new specification is to support the low voltage input protection now being included.
 

Tekron have announced the details of the TCG 01-E GPS clock with remote engineering access. Based on the ubiquitous TCG 01, the new TCG 01-E features an Ethernet UTP port for remote engineering management (rather than a RS-232 port). This Ethernet UTP port (TCP/IP) can also optionally provide NTP/SNTP output.

The UTP port also supports SNMP (Simple Network Management Protocol) allowing the TCG 01-E status to be monitored via other network devices.

Later this year, the TCG 01-E will also support, as an option, IEEE 1588 PTP (Precision Time Protocol). What’s really clever is that existing “E” clocks in the field will be able to be upgraded using the remote engineering capability, so you don’t need to delay implementing the new TCG 01-E today.

The TCG 01-E is the logical next generation clock for customers who’ve always specified TCG 01’s. However, Tekron is committed to supporting existing customers, so the TCG 01 will still be available for those who wish to retain full compatibility with the older design.

The TCG 01-E is supplied with a new improved Configuration Tool which supports the TCG 01-E, TCG 02-E and TTM 01-E. The existing configuration tool will remain available for TCG 01’s.

Remote engineering access via TCP/IP is now available with the following Tekron products:

• TCG 01-E     Fully featured GPS clock with multiple output options
• TCG 02-E     19” rack mount with 2 x IEC 320 power supply inputs (100-300 Vdc/85-264 Vac)
• TTM 01-E     Compact low cost GPS clock

The TCG 01-E is available for order now. Contact HV Power for price and availability.
