Qualitrol

Qualitrol is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Qualitrol rather than just read about it. In short: Qualitrol is a condition monitoring technology company headquartered in Fairport, New York. Qualitrol manufacturers and distributes partial discharge monitoring, asset protection equipment and information products for the electrical generation, transmission and distribution industries.

Key takeaways

Qualitrol belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Qualitrol to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Qualitrol from memory before moving on to harder problems.

Reference excerpt

Qualitrol is a condition monitoring technology company headquartered in Fairport, New York. Qualitrol manufacturers and distributes partial discharge monitoring, asset protection equipment and information products for the electrical generation, transmission and distribution industries. Qualitrol is a subsidiary of the Ralliant industrial conglomerate.

History In 1945, George Ford founded Qualitrol Corporation in Fairport, New York, to provide the electric utility industry with protective devices and monitoring systems. Ford opened a branch of Qualitrol in Waynesboro, Tennessee to manufacture valves. Later, Ford bought Microcontrol in St. Louis, Missouri, a manufacturer of thermostats, and the Dynapar Corporation in Gurney, Illinois a manufacturer of digital controls. In 1986, Danaher Corporation acquired Qualitrol, establishing Qualitrol LLC. Qualitrol became part of Danaher's instrumentation unit, which included Gilbarco Veeder-Root's underground fuel storage sensors, Dynapar's motion sensors, and Qualitrol's pressure and temperature measurement instruments used on the electrical transformer industry. Danaher spun off several subsidiaries, including Qualitrol, in 2016 to create Fortive. Qualitrol became part of Fortive in July, 2016.

Corporate affairs At the end of 2007, Qualitrol started to collaborate with Quebec City-based Neoptix Inc., a manufacturer of fiber optic temperature sensors. Initially, Qualitrol and Neoptix worked together on the integration of data collected simultaneously from traditional methods of temperature measurement and from optical direct hot-spot sensors. Subsequently, Neoptix became a sole subsidiary of Qualitrol. In 2010, Qualitrol acquired Mississauga, Ontario-based Iris Power, a supplier of on-line partial discharge testing of stator winding insulation in large motors and generators, from subsidiaries of Koch Chemical Technology Group, LLC, a Wichita-based multinational. Qualitrol thereby acquired a fleet of portable and continuous instruments and monitoring systems that are integrated into a power plant's Distributed Control System (DCS) or a Supervisory Control and Data Acquisition (SCADA) system.

At the end of 2011, Qualitrol began the expansion of its current production facility in Fairport, New York to 30,000 square feet (2,800 m2).

Global operations Qualitrol also has manufacturing facilities in Belfast, and Mississauga. The Belfast facility focuses on Qualitrol instruments and the Glasgow facility is now defunct and dissolved, merged with Belfast. The Quebec City unit operates as Neoptix and the Mississauga unit operates under Iris Power. Though each location specializes, projects are worked on by teams in multiple locations. Qualitrol adheres to the standards of international organizations, including the Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA) and the International Council on Large Electric Systems (CIGRE).

Worked examples

Example 1 — a first encounter with Qualitrol

Start with the simplest possible case. Write down what Qualitrol claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Qualitrol before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Qualitrol ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Qualitrol

In research: Qualitrol appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Qualitrol in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Qualitrol is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1945 establishments in New York (state), 1986 mergers and acquisitions, Companies based in Monroe County, New York, so understanding it makes those chapters shorter.
In everyday life: Look for Qualitrol outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Qualitrol in simple terms?

Why does Qualitrol matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
