- Basic test equipment - Understand the operation, application, and care of commonly used test equipment such as insulation resistance test set, contact resistance test set, and high potential test set.
- Important IEEE Standards
- IEEE 43 Recommended Practice for Testing Insulation Resistance of Rotating Machinery
- Test Equipment 101: The Basics of Electrical Testing It is the job of a test technician to know which piece of test equipment to use for the task at hand and also understand the limitations of the test equipment they are using.
- Insulation Testing
- Basic Test Equipment: Insulation Resistance Tester Most commonly referred to as simply a "megger," the insulation resistance test set (or Megohmeter) is used to determine the condition of insulation on various types of electrical equipment like cables, transformers and switchgear.
- The Complete Guide to Electrical Insulation Testing A comprehensive 64 page guide to electrical insulation testing containing helpful diagrams, value tables, product information and much more.
- Contact (low) Resistance Testing
- Low Resistance Testing Guide This guide covers the processes for low resistance testing, as well the optimal equipment to use, safety concerns and how to interpret results.
- Kelvin (4-wire) Resistance Measurements The Kelvin measurement can be a practical tool for finding poor connections or unexpected resistance in an electrical circuit.
- Bridge Circuits A Wheatstone bridge can be used to measure resistance by comparing the unknown resistor against precision resistors of known value, much like a laboratory scale measures an unknown weight by comparing it against known standard weights.
- Hipotential Testing
- What is HIPOT Testing (Dielectric Strength Test)? Hipot tests are helpful in finding nicked or crushed insulation, stray wire strands or braided shielding, conductive or corrosive contaminants around the conductors, terminal spacing problems, and tolerance errors in cables. Inadequate creepage and clearance distances introduced during the manufacturing process.
- Important IEEE Standards
- Multimeter use - Select correct multimeter scales and ranges. Recognize the limitations of ohm, voltage, and current scales. Recognize basic problems such as weak batteries or defective leads.
- Digital Multimeter Fundamentals An in-depth look at an indispensable tool
- How to measure resistance Steps for measuring resistance with a digital multimeter.
- ABCs of Digital Multimeters Learn how to make measurements, and how DMMs (Digital Multimeter) differ from one another.
- How to read an analog multimeter Although digital multimeters are far more common nowadays, using an analog test meter can still produce readings that are more than accurate enough for all but the most exacting requirements.
- Volt-Ohm-Milliampere Meter (VOM) A meter with a single D'Arsonval movement that can be used to measure multiple ranges of currents and voltages is called a multimeter. A common type of analog multimeter - a combination voltmeter, ohmmeter and milliammeter - is abbreviated VOM.
