Subject: Witnessing of field measurements with CSA certified Power Factor Correction Capacitors Cat. No. CMES-3D.
Dear Bill,
This letter will serve as our report on the subject matter that took place on April 2, 1996 at Abitibi Price Inc. Sheridan Park.
SCOPE
This exercise is to measure voltage, ampere, power factor and kilowatt in an electrical distribution system with and without using USES CMES-3D power factor correction capacitors. The unit is designed for three phase 347/600V applications and is generally installed using a 40A breaker on a distribution panel or with a 40A disconnect. The USES CMES-3D 600V is designed to be installed on inductive loads.
ELECTRICAL LOADS
On the second floor of the Sheridan Park Technology Centre was the ventilation system. In this system, there were several inductive motor loads rating between 50 horsepower to 5 horsepower, refer to Ill. 1. All loads were controlled from the MCC Control Cabinet in the second floor. This is where the USES CMES-3D 600V model was installed.
METERING USED
Two Tif instrument (Tif KW220-3AV)s were used to do the evaluation on USES CMES-3D 600V model. The first Tif was installed at the first floor electrical room next to the utility meter to evaluate savings. The second Tif was used at the load to evaluate if any changes were seen.
Two Amprobe (ACD-2000)s were used at the same locations to evaluate true RMS-Amperage readings.
Two Amprobe (7A)s were used at the same locations to evaluate the average amperage.
Two Protec (504)s were used at the same locations to evaluate the voltage.
Two Tif instrument (2300)s were used at the same locations to evaluate the power factor.
Also readings were taken from the utility supplied Digital Meter (Schlumberger VIP 2.5 ELX).
Readings were taken simultaneously when USES was energized and de-energized, meter was reset on each procedure.
Manufacturer provided the following illustrative material
1. Equipment floor plan Ill. 1
2. Readings measured Ill. 2 to 7
3. Data graphs Ill. 8 to 12
4. Conclusion Ill. 13
All the above information are on file in the Engineering department at CSA in Etobicoke, Ontario and are to be used for future reference.
With the completion of the above tests, this completes the scope of work originally contemplated for this project. The file No. LR 99910-7 has been closed and you will receive, in due course, a statement of your account as it concerns this application.

Re: Test Results of the USES® Product
CONCLUSION: Ill. 13 LR 99910-7
With the USES® CMES-3D 600V model energized into the Ventilation System Electrical System, at Abitibi Price, Inc. Sheridan Park Technology Center, Mississauga, Ontario, the following results were verified:
1] Voltage had a 2.3 Volt increase from 600.8 (Average) Volts to 603.1 Volts.
2] Amperage was reduced from 108.6 AMPS to 89.3 AMPS, a 19.3 Amperage reduction.
3] The Power Factor was increased from .86 to .99.
4] True KW was reduced from 96.1 to 92.3. This was a 3.8 kW reduction in consumption.
5] On the time evaluation, kWh consumption was reduced.
All test loads remained fairly constant due to the steady temperature outside. The air handling load ran constant during test procedures.
The loads on the complex were constant due to all variable loads were rendered inoperable during testing.
The following was observed at Abitibi Price, Inc. Sheridan Park Technology Center, Mississauga, Ontario:
- KW Savings
- KWH Savings
- Reduction of Amperage
- Voltage Regulation
- Power Factor Improvement
