Overview

The input, output, power supply and shell of the reactive power transducer are isolated from each other, which can prevent high-voltage signals from harming equipment and personnel. The compressive strength of the reactive power sensor is AC2Kvrms/min, and the insulation resistance is greater than 100 MΩ at DC 500V. It uses a 35mm standard rail or is fixed on a cabinet. The reactive power transducer has good quality and is easy to install.

Tips: Active Power Transducers vs. Reactive Power Transducers

Measurement Purpose: Active power transducers measure active power (W/kW) that performs actual work. Reactive power transducers measure reactive power (VAR/kVAR) that affects power quality but does no useful work.
Application Focus: Choose active power transducers for energy monitoring, efficiency analysis, and load management. Use reactive power sensing for power factor correction and reactive power compensation.
Load Type: Active power dominates in resistive loads (heaters, incandescent lamps). Reactive power is present in inductive/capacitive loads (motors, transformers, fluorescent lamps).
Power Factor Impact: The higher the active power, the higher the efficiency. Excessive reactive power results in lower power factor, resulting in wasted energy and higher costs.
