Get 3 phase power measurements 50% faster with Fieldsense clamp meters. How to measure 3 phase voltage and current simultaneously.

The need to measure three-phase electrical systems has become increasingly important, especially for simple energy surveys, more complex power quality troubleshooting, or overall electrical performance studies on individual electrical equipment such as transformers and motors.However, taking three-phase measurements can be dangerous as you need to open electrical panels and put on proper personal protective equipment (PPE). The top risks can carry severe penalties, whether it's personal injury or...

When a load is turned ON and OFF several times per second, this is duty cycle. It's the ratio of time a load or circuit is ON to the time a load or circuit is OFF. This is done to control things like lamp brightness, heating element outputs, or magnetic strength of a coil, for example. Many loads are rapidly cycled on and off by a fast-acting electronic switch to accurately control output power at the load.When measuring duty cycle, a digital multimeter displays the amount of time the input signal...

Whether you troubleshoot and maintain electrical distribution, HVAC, or rotating equipment you probably use a digital multimeter regularly. You may also use an infrared camera, or thermal camera to help you troubleshoot.The problem: Carrying two separate tools or having to go back to the shop to grab the thermal camera. Adding even more tools to a heavy tool bag or taking time away from the work to be done.The solution: A thermal multimeter, or thermal dmm, is both a digital multimeter and a thermal...

Resistance is measured using analog or digital multimeters. These tools also measure current, voltage, and more for various applications. Why measure resistance? To determine the condition of a circuit or component. The higher the resistance, the lower the current flow, and vice versa.In general, the resistance of components used to control circuits (such as switches and relay contacts) starts out very low and increases over time due to factors such as wear and dirt. Loads such as motors and solenoids...

Circuits and equipment may be designed to operate at a fixed or variable frequency. They may perform abnormally if operated at a different frequency than specified.For example, an AC motor designed to operate at 60 Hz operates slower if the frequency is less than 60 Hz, or faster if frequency exceeds 60 Hz. For AC motors, any change in frequency causes a proportional change in motor speed. A five percent reduction in frequency yields a five percent reduction in motor speed.Looking for your first...
