How to Install Substation Arresters.
- To install substation arresters, follow the directions, recommended work practices and be safe.
- Inspect the packaging and product, looking for signs of damage.
- Verify kV rating on nameplate, carton/crate label and shipping documents all agree. If they do not, stop and contact Hubbell Power Systems, Inc. prior to installation.
- Locate and read all installation instructions included with the packaging. If there are any questions, now is the time to ask.
- Prior to starting installation verify all hardware is included.
- Testing is not required prior to installation.
- Tighten all fasteners to the values in the installation instructions.
- For porcelain arresters point the directional vents away from other equipment.
- The stacking order of multi-unit arresters is very important. Verify the proper stacking order by reviewing the outline drawing with the packaging and the nameplate on the bottom unit.
- The use of any included grading ring is critical to life of the arrester. Verify the need for a ring by reviewing the outline drawing with the packaging.
- Hubbell Power Systems supplies stacking bolts but since mounting surfaces vary in thickness mounting bolts are not included. Grade 5 bolts should be used for mounting.
