EA Technology, specialist in asset management solutions for owners and operators of electrical assets, has launched an innovative new accessory for its UltraTEV Plus² instrument for partial discharge (PD) detection.

What is the UltraBolt?

The UltraBolt is a switchgear bolt with a built-in ultrasonic sensor. Once installed, it creates a fixed reference point for your UltraTEV Plus² and magnetic reader. Just connect, measure, and go – making Partial Discharge (PD) testing quicker, simpler, and more consistent.

Why Choose the UltraBolt?

Faster PD Testing

The UltraBolt connects to your UltraTEV Plus² instantly using the magnetic reader. There is no need to open panels or set up temporary sensors. This reduces time on site and makes routine PD checks quicker.

Increased Sensitivity

Fitted directly to the enclosure, the UltraBolt provides an internal ultrasonic sensor. This increases the sensitivity of readings and removes the need for air gaps.

More Consistent Results

With a fixed reference point for every reading, the UltraBolt eliminates variation between users. This delivers more reliable data, clearer trends, fewer errors and greater confidence in the health of your electrical assets.

Simpler for Frontline Teams

The UltraBolt is designed for use by anyone. No additional training is required. Just fast and simple PD testing whenever you need it.

No New Device Required

The UltraBolt works with your existing UltraTEV Plus². Attach the magnetic reader to the installed accessory and you are ready to go.

Built for Busy Networks

The UltraBolt is ideal for network operators, utilities and industrial networks. It makes routine condition monitoring more efficient and helps you detect issues earlier with less disruption.
