)
Wireless Phase Reference
Provides a reliable wireless phase reference, so partial discharge activity can be plotted against the power cycle first time.
)
UHF Directional Antenna
Picks up airborne UHF emissions across a substation, helping you narrow down where partial discharge is coming from.
)
UltraDish
Parabolic ultrasonic dish for detecting surface discharge and corona at a distance on outdoor and overhead assets.
)
UHF Barrier Spacer Sensor
Detects partial discharge in EHV and HV gas insulated switchgear by reading through the insulating barrier spacers.
)
UHF Receiver
Extends UHF detection into enclosed and gas insulated switchgear, where TEV and ultrasonic methods reach their limits.
)
UltraTEV Plus² Locator Probe
Narrows a TEV reading down to the individual panel or compartment generating the discharge.
)
HFCT Sensor Kit
Clamps around cable earth straps to capture partial discharge activity travelling along high voltage cables.
)
Ultrasonic Contact Probe
Reads ultrasonic discharge through the metalwork of sealed chambers, where there is no air path to the source.
)
Ultrasonic Flexi-Sensor
A flexible probe for reaching ultrasonic emissions in confined or awkward spaces inside switchgear.
)
Voltage Presence Indicating System (VPIS)
Connects to the switchgear's existing voltage indicating system to detect partial discharge in MV switchgear and cables.
)
UltraBolt
A switchgear bolt with a built-in ultrasonic sensor, giving a fixed reference point for faster, more consistent PD testing.

Not sure which accessory you need?
Every asset type and environment calls for a different detection method. Our partial discharge specialists can help you match the right sensors to your switchgear, cables and overhead lines, and build a kit around the surveys you actually carry out.
