    Communications protocol error codes (Modbus TCP, Modbus RTU, Fiber Optic TCP etc.)

    Hi Safety engineer here with a mechanical background. I've been looking at error codes for Ethernet TCP and Modbus TCP communications and have been wondering whether they can be used to indicate more than just the health of the communications cable, networking, etc. For example, is it possible...

    Hydraulic simulation of a system with fluid pills and spacers

    I need to simulate the time-varying pressure and flowrate in a complex piping system. The pipes connect storage tanks holding fluids that have very different density and viscosity. The overall system has manifolds, valves, pumps etc. The nature of the problem also means we must simulate the...

    Is NI LabView suitable for use as control system

    I am considering using NI Cards and LabView as the platform for a manufacturing control system and wonder what experienced Controls & Instrumentation engineers think about this option. Its clearly cheaper than using industrial PLCs and smooths the transition from prototype to production.

    Fire and Explosion Frequencies for transformers

    Can someone point me to statistics for oil filled transformer fires and explosion (frequencies, damage, loss of life, clean-up, etc). We have a range of voltages including 240->35kV and 35->4kV. Thanks

    EHV power lines underground - Costs vs Surface

    Does anyone have a comparison of costs and challenges for EHV distribution underground. I am interested in whether or not the lifecycle cost of a burried system is really much worse than for overhead lines. The base case system would consist of 500kV lines delivering 1000MVA. The length...

    Ignition risk from MV, HV and EHV lines

    I need to assess the ignition risk from MV, HV, and EHV lines and transformers in the vicinity of wells producing hot oil and gas. Can you all comment on whether you think bare overhead lines, sub-stations, and transformers are a potential source of ignition and, if so, then direct me to any...
