Model: HMJ9001-Q
Product Overview:
The HMJ9001-Q Partial Discharge Detector is a multifunctional handheld device that utilizes five advanced detection methods—Transient Earth Voltage (TEV), Ultrasonic, High-Frequency Current (HFCT), and Ultra High Frequency (UHF)—to detect partial discharge (PD) conditions in various power equipment.
It is widely applicable to equipment such as switchgear, ring main units (RMU), GIS, power cables, transformers, and overhead lines.
- TEV sensors are used for switchgear and RMU detection.
- Airborne ultrasonic sensors are used for switchgear, RMU, and overhead lines.
- Contact ultrasonic sensors are used for transformers and GIS.
- HFCT sensors are used for transformers and cables.
- UHF sensors are used for transformers and GIS.
The instrument is compact, lightweight, easy to use, and highly efficient for field detection.
The HMJ9001-Q can connect with power grid PMS platforms via USB, Wi-Fi, or Bluetooth to download work orders and upload test data.
