Beaver Electrical remains open for business. We are maintaining standard hours for regular requests and 24/7 availability for emergencies. We take pride in our ability to assist keeping critical infrastructure and industry in BC running; especially in this time of crisis.
Specific notes to our customers regarding modified procedures during the COVID-19 situation:
Only visitors with pre-arranged appointments will be permitted at all Beaver locations.
Counter sales all all locations will be suspended.
Sales orders across all channels (telephone, email, ecommerce, B2B PO, etc.) will continue to be filled within our typical order handing timelines.
Customer pickups (call orders) for product sales will be suspended. All product sales orders must be shipped on a Common Carrier.
Beaver will only accept shipments of equipment to Service Shops on a Common Carrier. On a case-by-case basis, with an appointment, Beaver may accept customer drop-offs to a Service Shop.
Beaver will only ship equipment from Service Shops on a Common Carrier. On a case-by-case basis, with an appointment, Beaver may accept customer pick-ups from a Service Shop.
Beaver Shop Service employees will only work on customer sites for emergency service.
Beaver is not scheduling new testing or routine maintenance jobs at this time. Jobs presently scheduled will be postponed; the Field Service Coordinator will be in touch with affected customers.
In addition to these measures, we are are following the guidance of the provincial government and their related agencies. We will apply their suggestions and requirements as required to protect the health and well being of our employees, customers, and the public at large.
Beaver Electrical Machinery is Canada’s only trained installer for AEGIS® bearing protection rings. When Beaver installs an AEGIS® protection ring, it is granted additional manufacturer’s warranty length.
We offer the following services to help prevent electrical bearing damage:
Bearing Cutting and Inspection
Shaft voltage testing
External AEGIS® Installation
Internal AEGIS® Installation
Your Bearings Can Fail from VFD-Induced Shaft Currents VFDs allow large energy savings and precise control. But they also generate electric voltages on motor shafts. These shaft voltages can discharge through the bearings, causing pitting, fluting, and eventual bearing failure.
Protect Your Bearings AEGIS® Shaft Grounding Rings are the leading bearing protection technology. They protect bearings by giving shaft voltages a “path of least resistance” to ground, so the shaft discharges through the ring, not the bearing. Unlike other shaft grounding products, AEGIS® rings are long-lived and maintenance-free, and can be installed inside or outside of the motor.
Through the Green Motors Practices Group, Beaver rewinds are simply better.
GMPG members maintain or improve original motor reliability and energy efficiency when rewinding or rebuilding electric motors. The rewind process is strictly controlled and consequently the motor iron losses are not affected.
We are able to offer electric utility financed incentives or rebates when our customer’s qualifying rewinds are meet the Green Motor Initiative’s (GMI) high process standards.
GMPG members achieve these efficiency goals through strict adherence to good repair practices, including Green Motor Practices Group Electric Motor Repairing Specification 2012 and ANSI/EASA Standard AR100-2015
The intent of this groundbreaking accreditation program is to evaluate service centers for evidence of compliance to assure that they are using prescribed good practices to maintain motor efficiency and reliability during electrical and mechanical repairs of electric motors. The program accomplishes this by use of independent, third-party auditors.

Beaver Electrical’s involvement
Beaver’s two locations are the only EASA AR100 accredited repair centers in BC. Both Beaver’s Nanoose Bay and Burnaby shops are accredited.
Scope of the program
Three-phase, squirrel-cage motors that are repaired in accredited service centers. As such, the scope of the program includes mechanical repairs as well as electrical rewinding.
Designed to assure usage of prescribed good practices
Helps maintain motor efficiency and reliability during repair
Covers 23 categories and over 70 criteria elements (See the Audit Checklist for details)
External audits conducted by independent, third-party auditors
Beaver Electrical Machinery, Ltd. in Nanoose Bay, British Columbia, has been approved as an EASA Accredited Service Center by the Electrical Apparatus Service Association (EASA).
EASA Accreditation of Beaver Electrical Machinery means that we have successfully demonstrated that we follows the prescribed good practices to consistently deliver quality electromechanical repairs that maintain or improve AC electric motor efficiency and “This achievement by Beaver Electrical Machinery affirms the company’s commitment to excellence,” said Linda J. Raynes, CAE, EASA president & CEO. “EASA’s Accreditation Program, just launched last summer, offers external validation that the company adheres to good practices by submitting to an independent, third-party audit.”
The criteria for becoming EASA Accredited are based on ANSI/EASA AR100-2015: Recommended Practice for the Repair of Rotating Electrical Apparatus and The Good Practice Guide of The Effect of Repair/Rewinding on Motor Efficiency.
Power factor is the ratio of real power flowing to the load divided by the apparent power in the circuit. It is a dimensionless number in the closed interval of -1 to 1. It is the ratio between Watts and VARs consumed (normally kW and kVAR). In an electrical power system, loads with low power factor (such as motors, fluorescent lamp ballasts, lightly loaded transformers, and other devices that generate a magnetic field) draw more current for the same amount of useful power as a load with a higher power factor.
Lagging power factor is penalized by utilities. Low (lagging) power factor draws more current than a load with a higher power. Utilities must use larger conductors and other equipment when their system has a low power factor.
Low power factor appears on a utility bill as a penalty or surcharge normally applied when a customer’s average power factor dips below 0.90 for a given period.
Power factor correction capacitors can be added to a system to correct the power factor and return it to a non-penalty value.
Leading power factor is a situation where too much capacitance is applied. High (leading) power factor can cause overvoltage and can amplify existing system harmonics.
Automatic Power Factor Correction Systems detect the correction required and dynamically add and remove capacitors or inductors from the system to achieve the target power factor.

How does BC Hydro penalize poor power factor?
BC Hydro customers on the Medium General Service or Large General Service tariff may be subject to surcharges if their power factor dips below 90% in a billing period.
90% – 100%
88% – 90%
85% – 88%
80% – 85%
75% – 80%
70% – 75%
65% – 70%
60% – 65%
55% – 60%
50% – 55%
Where will I see if I have a penalty?
Check line number 8 your BC Hydro utility statement. If your power factor is 89% or lower or you have a non-zero dollar value in the Power Factor row, you may be needlessly paying a surcharge!
Email a copy of your usage statement showing a surcharge to email@example.com and our engineering team would be glad to make a capacitor sizing calculation for you. Payback on a power factor correction capacitor install can be as fast as 3 months!
