3 204-3 Introduction Ohio Brass has been producing high voltage surge arresters since the 1950 s and offers a wide variety of DynaVar metal oxide gapless arresters designed to protect transformers, switchgear, and other equipment from switching and lightning surges. These arresters meet or exceed all requirements of the most current IEC standard and can be selected to match a range of contamination and energy requirements. Table 1 shows the Ohio Brass offerings included in this catalog. Table 1: Ohio Brass Catalog Offerings Arrester Type Line Discharge Class Material PVI-LP 2 ESP Polymer PVN 3 ESP Polymer PH3 3 Silicone Polymer PH4 4 Silicone Polymer H3 3 Porcelain H4 4 Porcelain H5 5 Porcelain Dedication to Quality Ohio Brass has demonstrated that its Quality Management system is in compliance with ISO 9001:2000 and maintains stringent testing controls in accordance with IEC to ensure that the customer receives high quality with every product. Ohio Brass also performs various Quality Assurance tests on every batch of metal-oxide varistor (MOV) blocks. The routine and design tests listed below, in addition to highly controlled manufacturing processes, ensure that Ohio Brass products demonstrate a superior level of quality. Our commitment to quality and continuous improvement is what the industry expects of its Leader. MOV Block Routine Tests: Physical Inspection Visual inspections are performed at several steps of the block manufacturing process. Rated Energy Test This procedure confirms the energy capability of each zinc oxide disc element. Residual Voltage Test Every block undergoes an 8/20 current wave impulse to verify its V-I characteristics. Watts Loss Test This test measures the AC watts loss and capacitive current characteristics of the disc. MOV Block Batch QA Tests: Square Wave Energy Test Performed on a 5 disc sample from each batch, this test is performed to quantify the batch energy capability. High Current Test Each 5 disc sample is subjected to two high current discharges of the same polarity to ensure high current characteristics. A/C Life Test The discs are placed under test conditions for a minimum of 250 hours to verify performance. Arrester Routine Tests: Physical Inspection Every molded rubber part, block, wrap module, brackets and completed unit is visually examined to reject defective products. Reference Voltage Test This test measures the voltage once a predetermined maximum peak current is reached. Partial Discharge Test This test ensures that the partial discharge level of the arrester does not exceed a level of 10 pc. Residual Voltage Tested on individual discs Arrester Type Tests: Testing Compliant with IEC Including: v Insulation withstand tests on housing v Residual voltage tests v Long-duration current impulse withstand v Operating duty tests v Short circuit tests v Internal partial discharge tests Design Test Reports are available at: v v Or contact your Hubbell Rep.

4 204-4 Table 2:Normally Recommended DynaVar Arrester U C for Various System Voltages System Line-to-Line Voltage Nominal Maximum Grounded Neutral Circuit Arrester U C Temporary Ungrounded, Impedance Grounded or Ungrounded Circuits (1) (2) (1) For normal duty. Line-to-line fault up to 30 minutes (2) For severe duty. Line-to-line fault up to 2,000 hours Arrester Application Example In grounded neutral circuits, a 110 kv system usually has a maximum line-to-line continuous voltage of kv rms. This kv divided by 3 equates to a 66.7 kv line-to-ground voltage. The appropriate DynaVar arrester for this application is an arrester with a Uc of 70 kv since it is the lowest standard Uc that will meet or exceed the systems 66.kV line-to-ground voltage. For ungrounded or impedance grounded systems, use the following selection guideline to choose the correct DynaVar arrester. For applications where a ground fault is expected to be removed within 30 minutes, the minimum Uc threshold is the maximum system line-to-line voltage divided by For extended operation under ground fault conditions up to 2,000 hours, the minimum Uc is the maximum system line-to-line voltage divided by DynaVar arresters are designed to be used where average ambient temperature does not exceed 40 C (104 F) and the daily maximum temperature does not exceed 60 C (140 F). For further assistance Ohio Brass application engineers are also available to provide system specific recommendations for many different arrester applications. Arrester Application The primary factor in determining the most appropriate arrester is its continuous line-to-ground operating voltage (Uc or COV). When selecting the appropriate DynaVar arrester for an effectively grounded neutral system, it is desirable to choose an arrester with the lowest Uc that will meet or exceed the systems line-to-ground voltage. The arrester application example illustrates the selection process that should be followed to choose the correct arrester for each system voltage.

7 IEC Temporary Over-Voltage (TOV) Capability with Prior Duty Voltage per unit Ur Voltage (KV) per unit Ur H4 PH4 PH3 H3 PVN PVI-LP Time (seconds) Temporary Over-Voltage Capability Hubbell arresters are gapless and consist of a column of metal-oxide blocks connected between line and ground. The blocks can withstand a significant power frequency overvoltage for a limited time, depending on the magnitude of any immediately preceding surge duty. This duty can be the result of switching surges on higher voltage lines, or from other sources. All of the TOV curves are available in the Design Test Reports which are listed in the table below. The entire set of Design Test Reports are available for download at the website: The temporary overvoltage capability can be determined from the TOV curve. The prior duty curve of this table is based upon absorption of rated energy immediately preceding application of the overvoltage.

8 204-8 Polymer Housed Arresters (Type PVI-LP & PVN) Construction Polymer housings are resistant to rough handling and will not shatter in case of a failure. In comparison to equivalent porcelain-housed arresters, these polymer housed gapless arresters are typically half the weight. This makes transportation, handling and installation much easier. The single-unit, high voltage designs provide improved contamination performance over multi-unit designs. Closer spacing Smaller line end castings and smaller grading rings allow closer phase-to-phase spacing. MOV blocks are centered and restrained with tightly woven fiberglass filament strands impregnated with epoxy resin. Minimal Internal Atmosphere Will not Breathe or leak which eliminates moisture ingress, a cause of arrester failure. For non-catalog polymer arresters that require higher creepage or special application please consult your Ohio Brass representative.

(2) Based on a 500A surge of 45-µs time to crest through 88kV Uc, and 1,000A surge of 45µs time to crest of 98 kv Uc and higher ratings PVN Mounting Arrangements Type PVN arresters may be mounted vertically, horizontally or underhung, provided the cantilever moment is not excessive. Underhung mounting requires factory assembly of the base mounting hardware at the top of the arrester to ensure proper shed orientation. For the correct underhung catalog number replace the third digit with 2 or 5 as shown in the PVN Ordering System on the next page. The PVN arrester construction is non-rigid, and will exhibit an observable deflection when cantilever load is applied. This deflection is normal and will not affect performance. The rated ultimate cantilever moment of the PVN arrester with the tripod base is 2260 N.m. The maximum working moment for the kv Uc is 1130 N.m. For 131 thru 180 kv Uc with the tripod base, the maximum working moment is 565 N.m. For the round cap base design, the maximum working moment is 339 N.m. NOTE: PVN arresters above 115 kv Uc are not recommended for horizontal mounting Power Frequency/ Minute Wet (kvrms)
