Florida State University’s Center for Advanced Power Systems (CAPS) has unveiled a new 24,000-volt direct current power test system, claiming it is the most powerful of its kind available at a university research centre in the world.

With a capacity of 5MW, the new system will give CAPS the ability to test electrical equipment in real-world conditions, says FSU, and companies looking to build next-generation power equipment will be able to test those in the Tallahassee-based facility.

“It’s a very long and expensive process for companies to do this at the electrical grid,” said Ferenc Bogdan, senior engineer and associate in research at CAPS. “We can now do all of that cheaper and faster here.”

To create the system, CAPS put together four individual 6kV, 1.25MW converters that can be arranged in any combination—in series or parallel—to form a flexible test bed for medium-voltage direct current (MVDC) system investigations. The MVDC system was built by ABB Inc. based on CAPS’ specs.

“This is the first time anyone has strung together four individual converters of this magnitude and operated them in a safe and controlled manner,” said Michael Steurer, senior research faculty and leader of the Power Systems Research Group at CAPS.

BC scientists debunk a myth within the theory of superconductivity — the phenomenon of electricity flowing with no resistance

Posted in: Report on January 17th, 2015

University of British Columbia physicists have detected ‘charge ordering’ in electron-doped cuprate superconductors for the first time, according to research published today in Science.

Charge ordering is a ripple-like instability at the electron level that competes with superconductivity and likely suppresses the temperature at which materials demonstrate superconducting properties. Until now, researchers had only observed the phenomenon in other forms of cuprate materials.

“The universality of charge ordering across these very different materials shifts our perspective, and could propel future breakthroughs,” says Eduardo H. da Silva Neto with UBC’s Quantum Matter Institute and the Max-Planck-UBC Centre for Quantum Materials, who led the experiment with researcher Riccardo Comin.

“We need to understand how charge ordering is formed in materials and ideally tune it, allowing superconductivity to occur at temperatures closer to room temperature,” adds da Silva Neto, who is a Canadian Institute for Advanced Research postdoctoral fellow at UBC.

“Our work opens up a new avenue to study charge ordering and the mysteries of superconductivity in these materials,” says UBC professor Andrea Damascelli, leader of the research team. “Now we can compare and contrast characteristics that are common across both flavours of copper-based materials — both hole- and electron-doped.”

Doping involves adding impurities (electrons or ‘holes’) into materials in order to spur the material to exhibit unusual behaviours such as high-temperature superconductivity.

Recent superconductivity research on charge ordering in hole-doped cuprates has focused on understanding its connection to another mysterious state: the pseudogap. Most experiments suggest that the pseudogap is a necessary ingredient to charge ordering, and consequently the suppression of superconducting properties.

But the UBC research indicates that the pseudogap is not a prerequisite for charge ordering in electron-doped materials.

Superconductivity — the phenomenon of electricity flowing with no resistance — occurs in some materials at very low temperatures. High-temperature cuprate superconductors are capable of conducting electricity without resistance at record temperatures, higher than the boiling point of liquid nitrogen. Because of their unrivalled characteristics, they represent the best candidates to advance current superconductor technology, which includes a broad range of applications such as: quantum computers, MRI, high-precision magnetometry, levitating high-speed trains, and lossless power lines.

SRP Electric takes on Toronto’s 401 Mini Indy

Posted in: Solar on June 12th, 2013

On January 30th, 2013, SRP Electric’s team set to work on installing a full-scale solar system on the roof of Toronto’s 401 Mini Indy. The 300kW system is one of the most advanced distributed architecture designs in the province utilizing 10kW string inverters and TIGO module level DC optimizers for maximum performance and module level reporting.

Over the course of the installation, SRP Electric’s goal was to ensure that the project was completed in a timely manner and that the job site remained clean and orderly throughout the process. Despite ongoing weather challenges such as snow, ice and rain, the team managed to complete the installation on schedule, working indoors when the weather was inclement and taking advantage of clear days to work on the roof.

SRP Electric’s synergy with SunRise Power meant that the engineering staff was always available to deal with issues promptly. According to Rick Yates, SRP Electric is always looking for a better way to do an installation.

Here are a few pictures from the job site:

Installing occupancy sensors in your home or business

Posted in: Residential on May 29th, 2013

When someone enters your home or business, you want to know about it. Similarly, when there’s no one around, why waste money to keep the lights on continuously?

Here’s another thing to consider: since no one wants to be left in the dark, who should be in control of the lights?

The answer is as simple as installing an occupancy sensor.

As home and business owners become more aware of the impact their habits have on the environment, as well as the rising cost of living, they begin to look for ways to save money and conserve energy. Occupancy sensors are typically installed in places in which the lights are expected to be on continuously, such as restrooms, warehouses, offices, and classrooms. After a few minutes of inactivity, the sensor automatically shuts off all lights, fans or other devices in the room, but will restart them if it detects motion.

Occupancy sensors operate using any one of the following three technologies:

1) Passive Infrared

How they work: detect heat energy.

Pros: work well in enclosed offices, warehouses and hallways where there is clear visibility and limited obstruction.

Cons: more sensitive to cross-motion than approaching motion; do not work well in restrooms or offices containing high-walled cubicles.

2) Ultrasonic

How they work: using high frequency, inaudible pressure waves that trigger the sensor when interrupted by a passing object.

Pros: work well in walled areas such as washrooms, as they are highly sensitive to any kind of movement and unaffected by physical barriers.

Cons: sensor effectiveness decreases as the distance between an object and the sensor increases.

3) Dual Technology: combines passive infrared and ultrasonic technology to prevent false on-off switching. In dual-operated sensors, both technologies are required to activate a device, but only one is needed to keep it on.

Electrical Safety Tips

Posted in: Residential on May 28th, 2013

The following tips were provided by the National Fire Protection Association.

– Replace or repair damaged or loose electrical cords

– Avoid running extension cords across doorways or under carpets

– In homes with small children, make sure your home has tamper-resistant (TR) receptacles

– Consider having additional circuits or outlets added by a qualified electrician so you do not have to use extension cords

– Follow the manufacturer’s instructions for plugging an appliance into a receptacle outlet

– Avoid overloading outlets. Plug only one high-wattage appliance into each receptacle outlet at a time

– If outlets or switches feel warm, frequent problems with blowing fuses or tripping circuits, or flickering or dimming lights, call a qualified electrician

– Place lamps on level surfaces, away from things that can burn and use bulbs that match the recommended wattage

– Make sure your home has ground fault circuit interrupters (GFCIs) in the kitchen, bathroom(s), laundry, basement, and outdoor areas

– Arc-fault circuit interrupters (AFCIs) should be installed in your home to protect electrical outlets


Installing a timer on your pool or spa pump

Posted in: Residential on May 23rd, 2013

A pool is a big investment and can cost a lot of time and money to maintain throughout the year. However, there are ways to save money and still enjoy your backyard when it’s convenient for you.

Most pool heaters – including those designed for above ground pools – can be outfitted with a timer to control when they run and for how long. Cycling your pool’s water at predetermined, off-peak times can help you reduce your electricity bill and spare you the trouble of remembering to check on your pool’s equipment during the day.

These aren’t the only benefits, of course. According to Rick Yates, Master Electrician at SRP Electric, pool timers can significantly reduce the length of time a pump is on, and in turn the amount of energy it uses. In addition, a timer can extend the life of your pool pump or heater, saving you money on repairs and replacements in the long run.

SRP Electric can ensure that your timer is installed properly and is performing at optimal levels. Intermatic’s diverse lineup of electronic, mechanical, and specialty controls, surge protection devices, and other accessories and enclosures can help you make the most of your pool or spa this summer.

Let SRP Electric help you with your next pool or spa installation by calling Rick Yates directly at 705-760-3270.

The T12 Lighting Ban – What You Need to Know

Posted in: Residential on May 22nd, 2013

What is a T12 light, and why is it being banned?

T12 fluorescent lighting is often found in many small business offices. As an older, more inefficient type of lighting, it has been the target of numerous Canadian Energy Efficiency regulations that seek to curb the production and use of inefficient general service fluorescent (GSFL) lighting in Canadian workplaces. Once the ban takes effect, offices that currently use T12 lighting will no longer be able to buy replacement bulbs.

What options are available for small businesses?

Through the Small Business Lighting program offered by Peterborough Distribution Inc., eligible business owners* can receive up to $1,000 worth of energy-efficient lighting and equipment upgrades. The switch to T8 fixtures will provide better lighting for your office, store or workplace while saving you money on your energy bill.

The program also includes:

– A free assessment of your business’s lighting and water heating equipment

– Free supply and installation of energy efficient lighting

– Licensed electrical contractor to install the new system at a time that’s convenient for you

– Recycling and proper disposal of your old lighting

Where can I find more information?
