Top causes of single-phase motor malfunctions

Most problems with single-phase motors involve the centrifugal switch, thermal switch, or capacitor(s). If the problem is in the centrifugal switch, thermal switch, or capacitor, the motor is usually serviced and repaired. However, if the motor is more than 10 years old and less than 1 HP, the motor is usually replaced. If the motor is less than 1/8 HP, it is almost always replaced.

Fundamental IAQ/HVAC measurements with the Fluke 975 AirMeter™

The 975 gathers ten fundamental IAQ parameters: Temperature, Humidity, Dew Point Temperature, Web Bulb Temperature, Carbon Dioxide, Carbon Monoxide, Air Velocity, Air Volume, and Percentage of Outdoor Air (calculated from temperature or CO2). This application note reviews those parameters and the associated functions on the 975. For more detailed information, see other app notes from the Fluke HVAC/IAQ library.

Insulation resistance and electrical testing for HVAC compressor motors

HVACR mechanics rarely rely on a single test to pass or fail a function or process. As they walk up to a condensing unit, they listen, they wave their hand over the condenser discharge air, and then they grab the suction line, the liquid line, and the discharge line (and wish they hadn't done that). All of this before they even open their tool box.

How to prioritize the leaks in your compressed air system using LeakQ

If your compressed air system is under-performing, your connected equipment will be too. Learn how to monitor and prioritize which air leaks to fix using the Fluke ii900 LeakQ mode.

Article

Expediting air leak detection

Even the smallest air leaks can compound product and energy waste and lost production time—especially for a production line that cannot function without compressed air to run its tools and processes.

Case Study: Three-Phase Motor Failure

For three years in a row, a particularly large three-phase motor would fail twice a year. The facility maintenance manager called in both the electrical contractor and the motor manufacturer, who pointed fingers at each other but failed to resolve anything on site.

Case study: Electric utility plays it safe...

The safety rated Fluke T+Pro gets field-tested by non-electricians. Larger buttons for gloved hands and a battery life indicator helped to make the transition from the old solenoid-based testers to the T+Pro much easier.
