 J OSL YN Manufacturing Co. Arresters Distribution Arresters Durability Riser Pole and Heavy Duty Distribution Class arresters have been called upon to serve in the most demanding of applications. Typically unshielded, ov erhead lines can produce some of the most severe lightning surges on the power system. Joslyn distribution arresters are designed to meet the demands of protecting underground and overhead equipment, respectively. Tested in accordance with the latest industry standard, ANSI/IEEE C62.11-1999 for Heavy Duty metal oxide arresters, Joslyn distribution arresters withstand the following minimum design tests: High Curr ent-Short Dur ation: 2 curr ent surg es of 100kA magnitude and 4/10 microsecond duration. Low Current-Long Duration: 20 current sur ges with 2000 micro-second duration and 400 amperes magnitude discharged through ‘ZRP’ and 250 amperes magnitude discharged through ‘ZHP’. Duty Cycl e: 20 dischar ges with a current su rge o f 10kA magnitude and 8/20 microsecond wave shape follo wed by 2 discharges with a current surge of 40kA magnitude. • Follo wing each o f these tests , the arrester s remain thermal ly stable and the discharge voltage change at the classifying current is less than 10%. For more details on procedures and results, request the product specific Certified D esign Test Report.  Insulating Bracket Joslyn’s polymer housed arresters are assembled complete with a molded glass reinforced polyester insulating bracket with greatly increased strength. This polyester bracket provides insulation between the arrester and ground after the ground lead disconnect has operated in the unlikely event of arrester failure. This bracket will accommodate a 1/2 inch carriage bolt on the crossarm bracket. Joslyn recommends that no more than 40 foot-pounds of torque be applied when installing the arrester on the crossarm mounting bolt. The bracket also uses a contamination deterrent crest down the centerline of the body of the bracket. This crest facilitates self-washing of contamination with rainwater. This feature reduces the risk of any contaminant build up on the top of the bracket between the skirts. ©2004 Joslyn Manufacturing Co. • 9200 W.

Terminal ConnectionsDistribution arrester line terminals utilize a stainless steel

four cornered “Star Clamp” for maximum conductor rangeand speed of installation. The ground terminals utilize astainless steel “U clamp”. Both connectors securely clampaluminum or copper conductors from No. 10 solid through2/0 stranded. Joslyn specifies that no more than 20 foot-pounds of torque be applied to the line and groundterminals.

Transformer ProtectionThe level of protection an arrester can provide will decreasewhen utilizing long connecting leads (line and ground side).This is due to the inductive voltage drop which is added to

the discharge voltage of the arrester. Mounting an arresterdirectly to the transformer will yield excellent protectivemargins from a combination of controlled lead length andlow discharge voltages.

Available OptionsFor options, see Catalog Selection Guides (page AR-19 thru

22) and Accessories (page AR-26 and 27).

Fault-Current Withstand TestsFault-current testing, also known as short circuit testing,demonstrates an arrester failure based on the most probablefailure modes over a range of fault currents. Two failuremodes are tested: 1) a fuse wire runs along the side of theinternal valve elements to simulate and internal flashover(moisture or collar failure), 2) overvoltage the arrester untilthe resistive elements fail to simulate a system overvoltageexceeding the unit’s TOV capability.

ANSI/IEEE C62.11 1999, specifies the test procedures andacceptance criteria for fault-current tests on distributionsurge arresters. Joslyn’s arresters passed the fuse wire andovervoltage fault-current testing at the current levels anddurations listed in the applicable Fault-Current Data Tables.Conformance was shown by oscillograph recordings of current magnitude and duration conducted through thearresters. All units passed the acceptance criteria.

Initial venting and arcing. Continued arcing. Following the severe fault, the arrester remainedintact.

Distribution, 5kA Dead Front Elbow Arresters

“ZE” SeriesRated 3-27kV

The type “ZE” arrester incorporates surge protection in aone-piece, shielded elbow housing. It permits arresterinstallation on standard separable connector bushings,maintaining the dead front concept.

Performance

The type “ZE” arrester was developed specifically forprotection of underground distribution systems. It isinstalled at the open point of the underground system toprevent voltage wave doubling. When also installed at anintermediate point, voltage reflections from the open pointarrester are harmlessly discharged. The housing, made of peroxide cured EPDM rubber, is totally shielded with amolded conductive EPDM jacket to maintain the dead frontconcept. The one-piece construction requires no fieldassembly. The “ZE” dead front elbow arrester is approved byREA.

Durability

The “ZE” elbow arrester consistently withstands the

following minimum design tests:

• High Current-Short Duration: 2 current surges of 40kAmagnitude.

• Low Current-Long Duration: 20 current surges of 75amperes magnitude and 2000 microsecond duration.

• Duty Cycle: 22 discharges with a current surge of 5kAmagnitude and 8/20 microsecond wave shape.

• Following each of these tests, the “ZE” arrester remainsthermally stable and the discharge voltage increase atrated current is less than 10%.

Reliability

Rigid control standards insure that all material conforms toexacting engineering specifications. Each finished arrester issubjected to electrical tests to determine reference voltage,total leakage current and corona levels.

Application

The type “ZE” arrester rated voltage designates the 60Hzvoltage applied across the arrester terminals during the dutycycle test. In addition, the type “ZE” arrester MaximumContinuous Operating Voltage (MCOV) designates themaximum power frequency voltage that may be continuouslyapplied across the arrester in service. Selection of theappropriate type “ZE” rating is made on the basis that themaximum continuous line-to-ground voltage on the systemdoes not exceed the MCOV of the arrester.

The 10kV, 18kV and 27kV rated arresters are designed forapplication on nominal 15kV, 25kV and 35kV UD systems,respectively. The three ratings include standard ANSI/IEEE386 separable connector interface designs that arecompatible with major interface suppliers at each voltagelevel. Consult Joslyn for your specific requirements.

Permanent Markings

For permanent identification, the “ZE” arrester has moldedinto the housing “JOSLYN ZE ELBOW ARRESTER”. Stampedinto the stainless steel cover are “JOSLYN ZE ARRESTER”,arrester rated voltage, and date of manufacture. In additionto the above, a label contains all other information includingcatalog number and both rated voltage and MCOV rating.
