Monitor partial discharge and configure monitor via computer, tablet or web-enabled device
Works with a variety of sensors including antenna for airborne PD, CTs for individual or bundled conductors, UHF drain valve probes for in-tank applications and bushing tap connectors
Built-in Expert System learns PD behavior and indicates changes in frequency and/or severity of measured PD levels
Alarm relays for external notification
Broadband RF signal detection including peak, average and quasi-peak
BENEFITS
Monitor PD in critical and high-risk assets
Save costly equipment by quickly reacting to rapid insulation deterioration warnings
Identify problem areas, diagnose the severity of the situation, plan action and intervention
Plan for further testing, maintenance and replacements in a proactive, risk management approach
Use as a standalone product, networked to existing SCADA system, or as part of a doblePRIME Condition Monitoring Platform
ACCESSORIES

Sensors & accessories
HFCT Sensor
Clip-on
10 kHz – 200 MHz
HFCT-300 Sensor
For use at cable terminations.
Hand-held split-core sensor specially designed for coupling out high frequency PD-signals
Applicable for PD tests on any part of the PD signal loop between the insulation electrodes where the outgoing and incoming signals do not cancel each other out
For highly sensitive PD measurements with superposed line currents or high reactive currents (50/60 Hz) which can reach up to 300 A
LDWS-T sensor
For use at HV cable terminations.
For decoupling of PD signals (TNC-socket)
High impedance version
For ungrounded and grounded devices
UHF Drain Valve Sensor DN50/DN80
For use with HV Transformers.
Designed for decoupling of electromagnetic PD signals from inside of transformers
Sensor fits into DN 50 or DN 80 drain valves
Supports “Performance/ Sensitivity Check” where High frequency test pulses can be injected with further integrated electrodes
Grounded sensors (for low frequencies)
UHF PD Plate Sensor
For use with HV Transformers.
Used for the decoupling of electromagnetic UHF PD signals from the inside of the transformer tank
Designed to retrofit transformers that do not have oil flanges with free internal tubes
Can be installed on new transformers during manufacturing
Used for testing and optimizing mechanical properties such as oil-tightness, thermal withstanding of changing temperatures and pressure withstanding
UHF Spacer Sensor
For use in GIS.
Antenna for polymeric spacers or glass inspection windows
The sensor can be placed across a joint on a GIS to find evidence of partial discharge inside
