Power Company Relationships

High Voltage Design

Our knowledge of industry requirements and government regulations makes us the ideal Engineering company to design a high-voltage electrical system for your site, from the main motor to your downstream and auxiliary equipment. We’ll take care of load forms, connection requirements, and coordination between the electrical service entrance and customer-owned equipment, along with sizing and specifications for substations, transformers, switchgear, capacitor banks, and other required equipment.

Demand Charge Limiters

Demand fees can account for up to 70% of your power bill and are generally based on the highest 15-minute demand in your billing cycle. Cut your power bills by thousands of dollars by reducing energy peaks while staying in control of demand charge parameters based on your production needs.

Harmonic & Flicker Analysis

Harmonic and flicker analysis requires application specification knowledge, in-depth distribution theory, and drive topology expertise. Quad Plus utilizes all of these competencies to develop precise mathematical models and deliver accurate and reliable analyses. We also collect all the data needed for negotiating with the power company and provide a power single diagram of the facility, flicker analysis, and recommendations for meeting IEEE and local quality standards. See our Flicker Mitigation with Clean Power Drive Case Study.

About Power Studies

Proven Design Process

We use a 3D modeling process so you can see exactly what you’re getting before it is built, and spot trouble to make changes and modifications before construction. Your drawings can be sent to your architect to ensure a perfect fit. Plus, because we already have exact specifications, upgrades and servicing are easier.

Repairing a problem with an Auto Shredder Control System

Premium Support

Secure remote diagnostics mean faster repairs. We offer on-site repair services from the best professionals in the business and treat each call as an emergency. Our customer service line is staffed 24 hours a day, 7 days a week to keep you up and running.

Auto Shredding DC Drives

DC Drives have faster load response, lower initial cost, can run at any speed, and have full torque at low RPM. Enjoy lower energy and maintenance costs with dramatic increase to productivity. Plus, DC drives can be located where you need them without expensive line upgrades or power condition equipment.

We offer the most cost-efficient approach to upgradeing to fully-digital, closed-loop controls including onsite installation and re-commissioning of your system to keep downtime to a minimum.

Wound Rotor Induction Motor Installation (AC Drives)

auto shredder wound rotor induction motor installation experts

A wound rotor induction motor (WRIM) is a type of induction motor where the rotor windings are connected through slip rings to external resistances. Adjusting the resistance allows control of the speed/torque characteristic of the motor. Wound rotor induction motors can be started with low inrush current by inserting high resistance into the rotor circuit; as the motor accelerates, the resistance can be decreased.

Compared to a squirrel-cage rotor, the rotor of the slip ring motor has more winding turns. The induced voltage is then higher and the current lower than for a squirrel-cage rotor. During start-up, a typical rotor has three poles connected to the slip ring. Each pole is wired in series with a variable power resistor. When the motor reaches full speed, the rotor poles are switched to short circuit. During start-up, the resistors reduce the field strength at the stator. As a result, the inrush current is reduced. Another important advantage over squirrel-cage motors is higher starting torque.

A wound rotor induction motor can be used in several forms of adjustable-speed drive. Certain types of variable-speed drives recover slip-frequency power from the rotor circuit and feed it back to the supply, allowing wide speed range with high energy efficiency. Doubly fed electric machines use the slip rings to supply external power to the rotor circuit, allowing wide-range speed control. Today, speed control by use of slip ring motor is mostly superseded by induction motors with variable-frequency drives.

Shredder System Analysis

Unexplained shaft failures and premature bearing failures mean frustrating downtime and costly repairs. If your vendors are pointing to one cause, but the problems are recurring, it’s time for a change. Quad Plus performs vibration, mechanical drive train, and system analysis to find the right solution and put an end to persistent failures and downtime.

Vibration Analysis

Vibration patterns can give an experienced hand a look into what’s going wrong with your equipment. Vibration analysis helps to determine exactly what caused a breakdown so the correct part is repaired. The result is faster, more reliable repairs and fewer recurring problems.

Vibration analysis is also an effective predictive maintenance strategy that can improve equipment reliability by identifying points of weakness before a major breakdown occurs. That way, you can schedule maintenance and downtime for times that work for your production goals.

prevent torsional resonance in your shredder control system

Rotational Mechanical System Analysis

Torsional resonance can be destructive to your shredder system. Mechanical drive train and system analysis, including vibration and torsional resonance analysis, is necessary to identify problems with your equipment.

We employ experienced mechanical engineers along with drive and motor specialists to identify the correct solutions to stop shaft and bearing failures and improve long-term reliability. Instead of pointing you to a vendor for a solution, we stay with the problem from start to finish: identify the issue, implement the solution, and monitor the results to ensure complete satisfaction. See our Shredder Torque Testing Report.

case study increase shredder load capacity recycling center needed to install a 2500 HP shredder load but local utility infrastructure upgrade estimate was prohibitively expensive

Shredder Load Capacity Case Study

The Quad Plus team was contacted by a local recycling center looking to install a 2500 HP shredder load. The local utility performed a load analysis and advised the customer that there was not enough power in the local distribution circuit to provide power to the proposed shredder. Their solution included a dedicated circuit and modifications to the substation, a solution that would work based on the power data given to the utility by the customer. However, the estimate from the utility was in the millions of dollars—a price tag the owner could not afford.
