MOEORW-UHF UHF PD Sensor for GIS Testing (300MHz-1500MHz) Send email to us

Product Overview

The MOEORW Cavity-Backed Slot UHF Partial Discharge Sensor is a high-performance, directional antenna specifically engineered for the ultra-high frequency (UHF) radiation measurement of partial discharges in high-voltage assets. Utilizing an advanced cavity-backed resonant slot structure, this premium sensor intercepts electromagnetic wave pulses propagating inside enclosed metal enclosures while isolating external substation background noise. It serves as a core sensory component for intelligent grid diagnostic networks, delivering exceptional signal coupling efficiency through specialized dielectric windows.

Application

1.Gas Insulated Gear (GIS) & GIT

Recommended Mounting: Flush-mounted externally on the dielectric window of spacer insulator flanges.

Detection Targets: Free metallic particles, needle protrusions, floating potential electrodes, and internal void discharges within epoxy insulators.

2.Oil-Immersed Power Transformers

Recommended Mounting: Tank wall embedded or flush-mounted directly onto the inspection port/hatch covers.

Detection Targets: Oil-paper insulation degradation, localized winding layer/turn PD, and internal high-voltage bushing tap discharges. 

3.High-Voltage Switchgear & Ring Main Units (RMU)

Recommended Mounting: Flush-mounted flush with the cable compartment walls or busbar chamber enclosure surfaces.

Detection Targets: Internal destructive arcing, cable termination tracking, and multi-phase busbar insulation breakdown defects.

4.Power Transformers with Metal-Tank Construction

Recommended Mounting: Flush-mounted on non-magnetic dielectric window plates integrated along the tank wall surfaces.

Detection Targets: Core grounding faults, surface tracking, and all bubble/void-induced PD types inside oil-filled transformer compartments. 

5.Cable Terminations & GIS-Cable Interfaces

Recommended Mounting: Flush-mounted in close, immediate proximity to cable sealing ends and interface joints.

Detection Targets: Cable accessory insulation slip, internal void formation, and severe interface tracking between the GIS and cross-linked cable terminations.
