- Inspection and maintenance - Verify correct type and ratings for the installation and use. Confirm correct bending radius, spacing, support, environment, connections, connectors, and terminations.
- Low Voltage Cable Testing and Inspection Techniques The following inspections and tests should be performed before energizing newly installed low voltage wire and cable rated 600V or less.
- Calculating Minimum Bending Ratios The following are the minimum values for the radii to which insulated cables may be bent for permanent training during installation.
- Wiring Methods and Materials [PDF] Overview of NEC Article 300 (General Wiring Methods) and 310 (Conductors for general wiring)
- Wire Temperature Ratings and Terminations Conductors carry a specific temperature rating based on the type of insulation used on the conductor. Common insulation types can be found in Table 310.13 of the NEC, and corresponding ampacities can be found in Table 310.16
- Tables of AWG wire sizes The table shows various data including both the resistance of the various wire gauges and the allowable current (ampacity) based on plastic insulation.
- Bending Radii and Pulling Tensions The minimum bending radii for single and multi-conductor cables rated 600 volts and less, and without lead sheath, shielding or armor.
- Medium Voltage Power Cable: MV 105 cables This article is used to explain the most popular styles of copper medium voltage (MV) power cables and their usage.
- Installation of Cables and Busways General overview of various cable and busway installation methods.
- Inspection and Test Procedures for Metal-Enclosed Busways Visual/mMechanical inspections and electrical tests for metal-enclosed busways.
- Guide to Low-Voltage & Limited Energy Systems from Mike Holt
- Cable Testing - Perform insulation resistance, ac, dc, or VLF applied-voltage and partial-discharge tests. Also perform cable and shield continuity tests. Interpret the test data.
- Tan Delta Cable Testing: Overview and FAQ [PDF] Tan Delta, also called Loss Angle or Dissipation Factor testing, is a diagnostic method of testing cables to determine the quality of the cable insulation.
- Field Testing of Medium and High-Voltage Cables [PDF] This article discusses the cable field-testing standards developed or under development by the IEEE Insulated Conductors Committee.
- What is Partial-Discharge Resistance? [PDF] Partial discharges occur when the local electrical field intensity exceeds the dielectric strength of the dielectric involved, resulting in localized ionization and breakdown.
- Diagnostics Field Testing of Medium-Voltage Cables [PDF] This article provides an insight into some of the more commonly used and successful cable diagnostic techniques commercially available for performing tests in the fi eld on extruded, medium-voltage, shielded power cables.
- Testing and Commissioning of MV/HV Cables Inspections and comissioning tests for medium voltage and high voltage cables.
- General Guidelines for Online Partial Discharge Testing of Power Cables Partial Discharge is a localised discharge in the insulation medium due to high voltage stress that does not bridge the space between the two conductors. Partial Discharge testing of Power Cables is one of the diagnostic methods to detect and locate incipient faults in the cable insulation.
- High voltage testing — Direct current (DC) DC tests are used mainly to do "pressure tests" on high voltage cables. Although the cables operate with AC, AC testing is not practical.
- Testing and Comissioning of 110kV Power Cable After Installation (Part 1) (Part 2) (Part 3)
- The right tools for accurate fiber-optic testing There are five industry-standard ways to test premisesfiber-optic cable (three for insertion loss and two for OTDRs), depending on how you use reference test cables for your setup.
- Optical Time Domain Reflectometer (OTDR) The Optical Time Domain Reflectometer (OTDR) is useful for testing the integrity of fiber optic cables. It can verify splice loss, measure length and find faults. The OTDR is also commonly used to create a "picture" of fiber optic cable when it is newly installed.
