Attention: Mr. Ron Ludwig

Supervisor, Electrical

Dear Sir:

Re: Oil Sampling and Analysis – North Vancouver Facility

We are pleased to submit the insulating fluid report and test sheets for the three (3) transformers

and one (1) OCB located at the North Vancouver facility. The transformer sampling was

performed by James Powell on June 7, 2016 in accordance with ASTM D923 and D3613

standards. The laboratory testing was completed by The Chemlab of Calgary. Review of results

and analysis was provided by the undersigned.

Based on the analysis of the laboratory results, all equipment is in good condition and suitable

for continued service. Once again, both the East and West transformers are showing elevated

Ethylene indicating higher temperature internal heating however, since there has been no

significant generation and all other dissolved gases and standard fluid quality tests are within

IEEE acceptable limits for in-service equipment, the units are of no immediate concern. Annual

sampling is highly recommended to monitor any further generation. The Sub 2 transformer is

filled with Natural Ester (FR3) – it appears there is elevated Ethane however, the limits indicated

are for mineral oil only. Natural ester generates Ethane under normal operation (test limit is

400PPM) therefore the current value is within acceptable limits. In addition, the interfacial

tension appears low however, the test limit is 18 for Natural ester. As such all values meet the

recommended test limits for natural ester. The OCB is showing all dissolved gases and tested

fluid quality properties to be within acceptable limits. All equipment is classified as category

Type 1. Equipment in this category shows acceptable test results, with some showing minor

elevated gas levels. Close observation of dissolved gases in the oil, along with the fluid quality

properties, provides the most valuable information about your equipment health. All units are

recommended for annual resampling with electrical tests performed at 2 year intervals. This

testing schedule will allow us to maintain a comprehensive trend of all properties, and provide

accurate analysis on the condition and operational reliability of your equipment. Please see

Section 3.0 – Summary of Results and Deficiencies for a complete breakdown.

2.0. SUMMARY OF TESTS

For your reference and confirmation of the specific tests performed and their analytical

value, we provide the following highlight information. All transformer tests were

performed as per the latest ASTM standards.

Specific tests performed include:

ASTM D1816 - Liquid Dielectric Test

The dielectric breakdown voltage of an insulating liquid is important as a measure of

the liquid’s ability to withstand electric stress without failure. It serves to indicate the presence of contaminating agents, such as water, dirt, moisture, cellulosic fibers or

conducting particles in the liquid, one or more of which may be present in significant

concentrations when low dielectric breakdown values are found by test. However, a

high dielectric breakdown voltage does not indicate that the concentrations of

contaminants that are present in the liquid between the electrodes are not large

enough to negatively affect the average breakdown voltage of the liquid when

tested by this method.

ASTM D971 - Interfacial Tension

This method has been shown by practice to give a reliable indication of the presence

of hydrophilic compounds. When certain contaminants such as soaps, paints

varnishes and oxidation products are present in the oil, the film strength of the oil is

weakened, thus requiring less force to rupture. For oils in service, a decreasing value

indicates the accumulation of contaminants and oxidation products, which may

attack the insulation and interfere with the cooling of transformer windings.

ASTM D1533 - Moisture Content

The electrical characteristics of an insulating liquid are deleteriously affected by its

water content. A high water content may make a dielectric liquid unsuitable for some

applications because a deterioration in properties such as dielectric breakdown

voltage may occur. This test is suitable for use in acceptance specifications, in control

of processing and in evaluating the condition of dielectric liquids in service.

ASTM D974 - Neutralization Number

The acid number of an oil is a measure of the amount of acidic materials present. As

oils age in service the acidity, and therefore the acid number, increases. A used oil

having a high acid number indicates the oil is either oxidized or contaminated with

materials such as varnish, paint or other foreign matter. This test serves as an indicator

of the potential of the oil to form sludge.

ASTM D1500 – Color Number

The color of a new oil is generally accepted as an index of the degree of

refinement. For oils in service, an increasing or high color number is an indication of

contamination, deterioration or both.

7 | Pa ge

ASTM D3612 - Dissolved Gas Analysis

Gas analysis is based upon the fact that both electrical insulating oil and cellulosic

insulation break down under abnormal thermal or electrical stress. The results of these

stresses are both volatile and non-volatile gases, known as fault gases. Gas analysis is

the technique that identifies fault gases, relates their quantity, generation rate and

relevant ratios to type and severity of fault.

Typical fault gases analyzed are:

Hydrogen H2

Methane CH4

Ethane C2H6

Ethylene C2H4

Acetylene C2H2

Carbon Monoxide CO

Carbon Dioxide CO2

Typical types of transformer problems that can be detected are:

thermal degradation

- low temperature

- high temperature (hot spot)

arcing

partial discharges

degradation of paper insulation

Increased frequency or periodic testing will significantly increase the value and

accuracy of fault gas analysis.

3.0. SUMMARY OF RESULTS AND DEFICIENCIES

Transformers typically can be broken down into the following categories:

Type 1 Transformers in this category show acceptable test results, with a few

transformers showing signs of minor non-serious overheating (re-test

recommended in one year). Variations of Type 1 transformers may exist

pending past records and age of units.

Type 2 This category covers any transformer showing test results where some concern

is evident (re-test recommended in six months).

Type 3 Transformers in this category show signs of serious fault gas concentrations or

very poor chemical properties (prompt re-tests or further investigations are

required).

Type 4 Mechanical deficiencies (corrective action to be taken as soon as possible or

as recommended).

Please refer to the test sheets (5 pages) for a detailed breakdown of results and

recommendations. Following is the Summary of Results and Deficiencies.
