Compact split-core fluxgate current sensors for 500 A and 200 A. They clamp onto an existing conductor and combine power-analyzer accuracy with enough bandwidth for waveform instruments. Voltage output on a BNC connector works with WT series and PX8000 power analyzers and with ScopeCorders and DLM oscilloscopes.
