Description
Hioki Clamp On Leak Sensor 9675 for Leak Current Testing
The Hioki Clamp On Leak Sensor 9675 is purpose-built for professionals who need accurate, repeatable measurement of AC leak currents in electrical systems. Unlike standard current clamps designed for load measurement, this sensor is optimized to capture very small currents that indicate insulation degradation, grounding issues, or early-stage electrical faults. Its precision design makes it an essential tool for preventive maintenance and safety inspections.
Insulation Fault Detection
At the core of the Clamp On Leak Sensor 9675 is a high-permeability magnetic material combined with a magnetic shielding structure. This design minimizes external noise and improves sensitivity, allowing the sensor to measure weak leak currents with confidence. With an amplitude accuracy of ±1.0 percent and stable phase performance at power line frequencies, technicians can trust the readings when evaluating insulation conditions or verifying grounding integrity.
Ground Conductor Monitoring
The sensor is rated for primary currents up to 10 A AC and is optimized for leak current measurement on insulated conductors. Its voltage output of 100 mV per ampere allows direct connection to compatible power quality analyzers, recorders, and data logging instruments with voltage input. This makes it easy to integrate into existing test setups without additional signal conversion equipment.
Field and Panel Inspections
With a compact clamp size and a core diameter of 30 mm, the Clamp On Leak Sensor 9675 is well suited for use inside control panels, distribution boards, and equipment enclosures. Its lightweight design reduces user fatigue during extended inspections, while the three-meter cable provides flexibility when connecting to measuring instruments. The sensor supports a frequency range up to 5 kHz, enabling analysis beyond basic power frequency measurements.
Preventive Maintenance Programs
By enabling early detection of leak currents, the Clamp On Leak Sensor 9675 helps maintenance teams identify potential insulation failures before they lead to equipment damage, downtime, or safety hazards. This makes it a valuable addition to routine electrical inspection programs across manufacturing plants, commercial buildings, and utility facilities.
