RD-33



Features



Measurement

The RD-3X Analyzing Standard registers both forward and reverse energy flow and provides voltage, current, power and energy (Active, Reactive, Apparent) information.



Meter and Standard Testing

The RD-3X Analyzing Standard is the ultimate instrument for on-site accuracy testing of electricity meters, performing power quality analysis, testing current transformers (CT), and site wiring confirmation. The Analyzing Standard is designed to work with customer load or a stand-alone current source.



Overview



The Radian Three-Phase Analyzing Standard is packaged in a robust case and features the performance of the Radian Research RD-3X family of reference standards. The Analyzing Standard provides unsurpassed accuracy, functionality, and ease of operation.



Radian’s Analyzing Standard is so versatile that the functionality is like having three instruments in one.   The standard is the ultimate instrument for on-site accuracy testing of electricity meters, performing power quality analysis, testing current transformers (CT), and site wiring confirmation. The Analyzing Standard is designed to work with customer load or a stand-alone current source.



Highlights

• Selectable accuracy classes 0.01% -0.04%
• Four quadrant measuring instrument for Active, Reactive, and Apparent power measurements
• Optional built-in computer with touch screen and anti-glare color display
• Analysis up to the 100th Harmonic
• Data Storage and Transfer
• Wide measuring range with autoranging potential and current inputs
