Power Quality Accessories
Power quality accessories encompass the supplementary probes, adapters, cables, and carrying cases that extend the capability of power quality analyzers, power loggers, and energy meters. High-capacity current probes — including large-jaw clamp sensors and flexible Rogowski coil transducers — allow instruments to measure currents well beyond their standard built-in ranges, enabling work on main service panels, industrial feeders, bus bars, and large motor loads where conventional probes are inadequate.
Selecting the correct accessory is critical: current rating, jaw opening, frequency response, and accuracy class must all match the measurement scenario and the host instrument's specifications. A well-chosen accessory set allows a single power quality analyzer to cover branch circuits, sub-panels, and main service entrances without compromising measurement accuracy or safety ratings.
Typical Applications
- High-current measurement on main feeders using 5000A-rated AC current probes
- Extending the current range of power analyzers for large transformer and motor measurements
- Energy auditing on industrial distribution systems with oversized bus bars or conductors
- Adapting power quality instruments to non-standard connector types or panel configurations
