INTRODUCTION
Mr. Jeff Kester, Arrester Engineering Manager, of Cooper Power Systems, requested the Georgia
Institute of Technology National Electric Energy Testing, Research & Applications Center
(NEETRAC) to perform various arrester design tests per IEEE C62.11™-2005. The sample set
requested for testing consisted of 10 kV, 18 kV, and 27 kV Cooper Evolution, heavy duty,
distribution class arresters. The arrester test samples were provided by Cooper Power Systems.
Testing was performed by NEETRAC personnel during the month of June, 2010, at the NEETRAC
High Voltage Laboratory in Forest Park, Georgia USA. All tests were witnessed by Mr. Jon
Woodworth, Consultant, of Arrester Works.
See Table 23 on page 19 for a summary of the results.

Test samples were provided by Cooper Power Systems. Sample descriptions are listed in Table 1.

PROCEDURE & RESULTS
Tests were performed in accordance with IEEE C62.11™-2005 Standard for Metal-Oxide Surge
Arresters for AC Power Circuits (> 1 kV) and IEEE Standard 4™-1995 Standard Techniques for
High-Voltage Testing. The test program consisted of the following clauses from IEEE C62.11-2005:
1. Clause 8.4.2.1.1 Front-of-wave impulse sparkover determination test, and
2. Clause 8.4.2.2.1 The 1.2/50 impulse sparkover determination test.
The tests outlined in the above clauses of the standard are used to establish product ratings and do
not contain pass/fail criteria. All of the above tests were performed on three samples of each voltage
class. The fourth sample was used as a set up sample for some of the tests.
Clause 8.4.2.2.1 The 1.2/50 Impulse Sparkover Determination Test
Three each of the 10 kV, 18 kV, and 27 kV arresters were tested. The results from this test
determined that the additional tests of Clause 8.4.2.2.2 were not required. Typical impulse test
setups are shown in Figures 1 and 2.
According to the Cooper Evolution arrester published literature Document 235-99, dated May, 2009,
the arrester discharge voltage at the classifying current of 10 kA is 25.4 kV for the 10 kV samples,
47.8 kV for the 18 kV samples, and 68.0 kV for the 27 kV samples.
The 1.2/50 impulse sparkover determination test results are shown in Tables 2 through 11. Circuit
setup test shots were performed on the spare (fourth) sample of each voltage class. The full impulse
log is contained in Appendix A.

From IEEE C62.11-1995, Clause 8.4.2.2.1, “The maximum arrester voltage recorded during the five
positive and five negative polarity standard lightning impulses shall be compared to the discharge
voltage obtained with the currents in Table 6 (of C62.11). If the classifying current discharge
voltage exceeds the voltage values measured during the impulse test described earlier, the classifying
current discharge voltage is the 1.2/50 impulse protective level, and no further testing is required on
this wave shape. If the voltage measured during the impulse test exceeds the classifying current
discharge voltage, proceed to 8.4.2.2.2 to determine the 1.2/50 impulse protective level.”
A comparison of the results from this test and each sample’s voltage class respective classifying
current discharge voltage is shown in Table 11. According to IEEE Standard 4-1995, Clause 7.5
Tolerances: “If not otherwise specified by the appropriate apparatus standard, the following
differences are accepted between values for the standard impulse and those actually recorded:
a) Peak value ±3% ....” IEEE C62.11-2005 does not designate a tolerance for the results in Clause
8.4.2.2.1; therefore, the tolerance from IEEE Standard 4-1995 is used. Since the highest 1.2/50
sparkover voltage measured for each sample did not exceed the classifying current discharge
voltage, within measurement tolerance, the tests described in Clause 8.4.2.2.2 The 1.2/50 Impulse
sparkover test were not necessary.

Clause 8.4.2.1.1 Front-of-Wave Impulse Sparkover Determination Test
Three each of the 10 kV, 18 kV, and 27 kV arresters were tested. The rate of rise (slew rate) was
determined by definition 3.54 nominal rate of rise (of an impulse wave front) from IEEE C62.112005 which states that it is the slope of the line that determines the virtual zero. From IEEE
Standard 4-1995 High Voltage Testing Techniques, the line that determines the virtual zero of an
impulse voltage wave front is drawn through the 30% and 90% points of the impulse peak.
Therefore, the rate of rise for this test was determined by the slope of the line drawn through these
points. Since no tolerance was stated for the rate of rise in IEEE C62.11-2005, a value of ± 5% was
agreed upon. Table 12 contains the parameters for this impulse test.

Five impulse applications of each polarity were required. Tables 13 through 22 contain the results of
the front-of-wave impulse sparkover determination test. The full impulse logs are contained in
Appendix A. The complete front-of-wave spread sheet is contained in Appendix B.

CONCLUSIONS
Tests were performed in accordance with IEEE C62.11-2005 Standard for Metal-Oxide Surge
Arresters for AC Power Circuits (> 1 kV) and IEEE Standard 4-1995 Standard Techniques for HighVoltage Testing. The test program consisted of the following clauses from IEEE C62.11-2005:
1. Clause 8.4.2.2.1 The 1.2/50 impulse sparkover determination test, and
2. Clause 8.4.2.1.1 Front-of-wave impulse sparkover determination test.
The tests outlined in the above clauses of C62.11-2005 are used to establish product ratings and do
not contain pass/fail criteria. Table 23 contains a summary of the results for each test clause.
