Press Release Summary:
VPD Live addresses needs of utility industry for energizing digital relays requiring 0.5-2.5 VA. It comes in transformer-mounted package that can be used for single phase or 3-phase applications. VPD Live can also be used as Power Factor/Tan monitor for transformer bushings with optional portable software, or continuous on-line monitoring device.
Original Press Release:
On-Line Monitoring Inc. Introduces 'VPD Live' For Energizing Under-voltage Relays
On-Line Monitoring Inc. of Exton, PA, introduces a new Voltage Potential Device, VPD Live to address the growing needs of the utility industry for a low cost, easy to install device to energize modern digital relays.
Over the past several decades, the industry standard Bushing Potential Device (BPD) weighing more than 350 lbs. was used to energize relays. The BPD was designed to energize electro-mechanical relays which needed all the power that these BPD's provide.
Today's modern digital relays require 0.5 to 2.5 VA and require a simpler easier to install interface. The VPD provides that interface in a convenient, transformer mounted package that can be used for single phase or three phase applications.
The VPD Live:
o Weighs less than 11 lbs
o Is available as a single phase or three-phase device
o VPD Live provides the user a 70% cost savings when compared to the cost of a legacy Bushing Potential Devices.
In addition, the VPD Live can be used as a Power Factor/Tan δ monitor for the transformer bushings with optional portable software, or a continuous on-line monitoring device.
One Utility in the Southwest USA is now implementing a plan to install more that 170 transformers with the VPD Live over the next 12 plus months. The VPD Live in each case will be feeding a digital under-voltage relay.
On-Line Monitoring Inc. is located in the Philadelphia metropolitan area, and they manufacture the SOS Tan d, PF Live, and PF Live Plus systems. They have monitoring systems installed on thousands of bushings world wide.
