Electrical Engineering Editing and Proofreading Services

An arc flash study is a substantial piece of engineering — a model of the network, fault current calculations, protection settings, incident energy at every point of work. Its output, the thing that stands between an electrician and a serious burn, is a label the size of a postcard stuck to a panel door. Everything upstream is invisible on the day. The label is either right, current and comprehensible, or the whole study was an expense.

We edit what electrical engineers and power system specialists produce — arc flash and incident energy study reports, protection coordination and discrimination studies, equipment labelling schedules and label text, load schedules and diversity assumptions, cable calculation and sizing documentation, earthing and bonding design reports, switching and isolation procedures, electrical safety rules and permit documentation, single line diagram notes and conventions, harmonic and power quality studies, installation and condition report observations, and design basis and specification documents for distribution systems. Our editors work on the document that reaches the person with the tools.

Labels and their underlying schedule are the delivered product of an arc flash study, and they fail in three familiar ways: they carry results the reader cannot act on, they contradict the study when settings change, and they describe a configuration that no longer exists. We write these so the label gives the boundary and the required protection in the terms the worker uses, not only the calculated energy, since a number in calories per square centimetre is a result and a stated equipment class is an instruction; so the operating configuration the result depends on is named on the label, because incident energy with the tie open and with the tie closed are different numbers and only one of them is on the panel; so the study report states which protection settings the results depend on and requires the label to be reissued when they change, given that a settings change is a routine act that silently invalidates a safety document; so the date and revision are on the label and the schedule is written so a reader can tell whether it matches the installation; and so anything outside the study's scope is labelled as unstudied rather than left blank, as a blank panel reads as a safe one. Studies that end this carefully are the ones that do what they were bought to do.

Everything you send is treated in confidence, including network data, studies and site documentation. We are editors rather than electrical engineers, and we offer no view on calculations, settings, labelling requirements or safe systems of work. What we can do is make the last hundred millimetres of the study as careful as the rest of it.
