Valquest’s RTUs provide a cost effective solution for expansion of your system and integrate with your existing network, securely connecting real-time utility field information between many different devices. The VQ series of RTUs operate with new and older ‘legacy’ devices, over many different types of communication networks, providing true multi-vendor, multi-function interoperability.
The VQ-3015 serves as an expansion module to the VQ-2015 with versatile communication in analog and digital form. By monitoring opto-coupled digital inputs, the VQ-3015 reads your PTs & CTs, calculates kVAr, kW, Power Factor, Phase Angle, and stores the status information in non-volatile memory.
The VQ-3015 reads Voltage information from PTs and Current information from CTs and then calculates:
- Phase Angle
- Power Factor
The VQ-3015 monitors opto-coupled digital inputs and stores the status information listed above. It responds to queries from a VQ-2015 with this analog and digital information. It also operates relays based on commands received from a VQ-2015.
- VQ-3015 is field programmable through a VQ-2015 RTU.
- Calibration and functional verification is done with the same program.
- Settings and calibration factors are stored in non-volatile EEPROM.
