  • Page 5: Introduction

    1 INTRODUCTION 1.1 Product Overview The TRANSFIX™ family of products (herein referred to as the product, meaning the TRANSFIX 1.6, MULTITRANS and TAPTRANS) are on-line DGA (Dissolved Gas Analysis) systems for transformer diagnostics. The products measure the following key fault gases in the transformer oil: hydrogen, methane, ethane, ethylene, carbon monoxide, carbon dioxide and acetylene.
  • Page 6: Manual Scope

    1.2 Manual Scope This manual details the installation requirements and procedure, including important pre- installation tasks to be considered when planning and preparing for the installation. It examines mounting, plumbing, power, electronics and communications — including tools, supplies and items to purchase. Differences between the products are always qualified by the use of the respective product name and operational details can be found in the respective product user guides.
  • Page 7: Safety

    The installer shall also ensure that any third-party equipment, such as an approved platform, scaffold or lift is suitable and safe before commencing work. Ladders or improvised platforms do not meet GE service engineer requirements. Once installed, the product may have more than one source of supply.
  • Page 8 Only GE-trained and certified personnel may commission GE products. Commissioning tasks include making any connections and/or performing any work within the enclosure, or performing tasks such as purging the oil circuit between the transformer and the product, and/or all first start-up procedures relating to equipment or firmware/software.
  • Page 9: Requirements

    In addition, the GE Customer Service Centre representative will need specific information in order to provide recommendations for a trouble-free installation. If GE is to perform the installation, the installation will not be scheduled until all pre-installation tasks outlined in this manual are complete (as performed by the customer and GE).
  • Page 10: Technical Specification

    200ml or less. For oil temperatures colder than -20 ºC, GE recommends the use of heat trace cabling on piping.
  • Page 11: Compliance

    5 COMPLIANCE The product meets the following type tests as listed in Table 5—1: Table 5—1: Type tests Category Standard Class/Level Test EMC Emissions – CISPR 11 Radiated & Conducted Emissions EN 61326-1:2006 FCC Part 15 Radiated & Conducted Emissions EN 61000-3-2 Harmonic Current Emissions Limits...
  • Page 12: Transformer Criteria

    6 TRANSFORMER CRITERIA The transformer shall meet the following criteria:  The transformer contains mineral type oils (paraffinic or naphthenic) that meet the requirements of IEC 60296, BS EN 60296, VDE 0370 or ASTM D 3487.  The transformer oil must be certified PCB free. ...
  • Page 13: Mounting

    (See Appendix G and Appendix H.) If a new concrete pad is required, GE recommends that it be at least 61 cm (24 in.) wide by 122 cm (48 in.) long and 9 cm (3 ½ in.) thick with a #3 (10 mm) steel reinforcing bar around the perimeter.
  • Page 14 If mounting to the body of a transformer, GE’s recommendation is to do so with the top half of the GE-supplied mounting stand. If there is concern about extreme vibration on a transformer, GE strongly advises against mounting the product to the body of a transformer.
  • Page 15: Plumbing

    8 PLUMBING The product removes oil from the transformer, extracts the gases, analyses the gases and then returns the oil to the transformer. The locations from which the oil is removed and to which it is returned are important for the accurate analysis of the gases (see Figure 8—1 and Figure 8—2).
  • Page 16: Transformer Valves

    8.1 Transformer Valves The possible valve locations of a transformer are shown in Figure 8—3. Figure 8—3: Transformer Valve locations 8.1.1 Fill Valve If the transformer is nitrogen blanketed, the fill valve or any other valve at the top of the transformer should not be used as an oil supply valve because there is no guarantee that there will always be oil at this position.
  • Page 17: Cooling Loop Valves

    Ensure that the valve chosen to return oil is not internally piped to another location within the transformer, such as the headspace or the internal windings. 8.1.4 Cooling Loop Valves The product should only be supplied with oil from a cooling loop valve if there are no other valves available.
  • Page 18: Oil Return

    (see Figure 8—11). Note: An optional manual oil sampling arrangement can be fitted to the oil inlet on the base of the product. For more information, contact the GE Customer Service Centre. 8.3 Tubing Stainless steel tubing is used to connect the product to the transformer.
  • Page 19 Note: Products, such as MULTITRANS, that are connected to more than one transformer must have suitable dielectric fittings placed in-line with the tubing and installed close to the product (see Appendix E for more details). Consider these points when choosing where to route the tubing and estimating how much tubing is required: ...
  • Page 20: Fitting Requirements

    8.3.1 Fitting Requirements Figure 8—4 to Figure 8—6 shows the bottom plate connection points for each product. The stainless steel tubing should be fitted between the transformer and the product as follows, ensuring that:  The supply line is connected to the OIL IN port (this is the bulkhead fitting at the bottom of the product that is located closest to the right-hand-side when viewed from the front).

    (See Section D.6). Tubing Unions Tubing Unions connect two pieces of the above ¼ in. tubing together. GE recommend:  Swagelok: SS-400-6 Stainless Union, ¼ in. OD  Ham-Let: 762L SS 1/4 Stainless Union, ¼ in. OD Shut-Off Valve If the oil supply or return valve is located more than 6 ft (1.82 m) above the base of the...
  • Page 41 D.6.1 Flow Rate The solid seamless stainless steel tubing that GE specifies is 316 Stainless Steel, 1/4 in. OD with a 0.035 in. thick wall. Most 1/4 in. copper tubing has a greater wall thickness which reduces the flow rate rendering it too fragile to place in the field. Bends in standard soft copper tubing crush and deform more easily, which can reduce the flow rate than would otherwise be the case with properly bent stainless steel tubing.
  • Page 42 GE will not guarantee or perform warranty work on a product that has been installed using copper tubing or any other tubing, other than stainless steel, as specified above.
  • Page 43: Appendix E Dielectric Fittings

    Appendix E Dielectric fittings TRANSFIX-family products that are to be connected to more than one transformer, such as the MULTITRANS, must have suitable dielectric fittings placed in-line with the tubing and installed close to the product. Dielectric fittings provide electrical isolation and prevent circulating currents from flowing in the tubing circuits.
