The electrical power issues that most frequently affect industrial plants include voltage sags and swells, harmonics, transients, and voltage and current unbalance.
This article demonstrates how to detect the 13 most common causes of winding insulation and bearing failure in advance.
How to measure output voltage from a VFD to a motor
Troubleshooting the most common power quality problems—voltage distortion and harmonics. Tools needed, types of problems
Monitoring three-phase power quality is a must. Whether you troubleshoot mysterious electrical problems or provide additional services to a client, it is three-phase power that is provided to commercial and industrial customers and three-phase power that is distributed throughout a facility.
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.
This how-to guide explains why and how to conduct a duct traverse, how to insert the measuring device and a step-by-step process of taking the measurements. Tips and additional resources are included.
エネルギー独立性の推進と再生可能エネルギー利用の高まりにより、HVAC 技術者は太陽光発電システムのトラブルシューティングについて理解を深めておく必要があります
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.
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.
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.
200 馬力のコンプレッサーで生成した圧縮空気で約 400 個のツールを稼働する 13,935 平方メートルの工場で導入されている、空気漏れ検知器による機器停止の防止策についてご覧ください。
Using infrared cameras to troubleshoot motor problems as well as monitoring motor conditions for preventative maintenance in power generation, manufacturing and commercial plants.
With the growing concern about mold damage and associated health problems, inspectors are becoming increasingly vigilant in checking for areas of moisture within the confines of the building envelope. Weather related damage and flooding, and subsequent mold growth, have also escalated the need for tools that can facilitate fast and accurate moisture investigations.
Seeing a motor’s heat signature under normal operating conditions—with at least 40 % of design load—can tell you a lot about its condition.
