At ESNAD, we provide the technologies and equipment needed to detect, monitor, protect, and improve critical electrical assets.
Our product portfolio brings together advanced inspection and condition-monitoring technologies, electrical equipment, protection systems, and critical power solutions from established technology providers.
From thermal, acoustic, and gas detection to partial discharge monitoring, OHTL monitoring, ATS and STS systems, UPS, disconnect switches, surge protection, and power factor correction, our solutions are selected to meet the technical and operational requirements of modern electrical infrastructure.
We focus on providing reliable, technically appropriate solutions that help our clients identify potential issues, improve asset performance, enhance operational reliability, and support more effective maintenance.
Handheld acoustic imaging cameras that locate compressed-air and gas leaks, and partial discharge on energised equipment, by mapping ultrasonic sound onto a live camera view. Faults are pinpointed from a safe distance with the plant still running. We supply the units and train your team to read the results.

Thermal imaging cameras that reveal heat patterns across switchgear, busbars, terminations and rotating equipment, exposing loose connections and overloads before they fail. Surveys run on live plant with no interruption to supply. We supply the cameras and can deliver the inspection programme alongside them.

Optical gas imaging cameras that make invisible escapes visible on screen, including SF6 losses from switchgear and hydrocarbon leaks on process plant. Leaks are traced to source quickly and from a safe standoff. We supply the equipment and support the survey methodology behind it.

We provide security camera solutions for industrial, commercial, and critical infrastructure applications, including explosion-proof cameras for hazardous and classified areas, multispectral and thermal cameras for advanced monitoring, and PTZ cameras for wide-area surveillance. We size and supply the appropriate camera systems and integrate them with existing monitoring and security platforms.

Automatic transfer switches that move critical low voltage loads from a failed primary supply to a standby source within seconds. Used where downtime is not acceptable, from hospitals and data halls to process plant. We supply, install, test and commission complete ATS panels and maintain them afterwards.

Static transfer switches that shift load between two independent AC sources in a fraction of a cycle using solid-state switching, with no moving contacts. The changeover is fast enough that connected equipment never sees an interruption. We specify them and integrate them into critical power distribution.

Ultrasonic instruments that catch early bearing wear, lubrication faults, cavitation and failed steam traps by listening to the sound signature of running machinery. Problems surface while the asset is still in service. We supply the instruments and can run the condition monitoring routes with your team.

Monitoring systems that detect partial discharge inside medium and high voltage insulation — the earliest measurable sign of insulation breaking down. Continuous or periodic measurement allows intervention long before a failure. We supply, install and interpret the systems as part of condition-based maintenance.

Monitoring for overhead transmission lines covering conductor temperature, sag, ampacity and general line condition. The data supports dynamic line rating, so capacity decisions and reinforcement can be made on evidence rather than assumption. We supply the hardware and feed the output into your asset management process.

Low voltage UPS systems that carry critical loads through supply disturbances and bridge the gap until standby generation picks up. Sized against real measured load profiles and the autonomy actually required, not nameplate figures. We supply, install, test and maintain the systems and their battery banks.

Low voltage disconnect and safety switches that give visible, lockable isolation for maintenance and emergency use. Correct selection and installation is what makes safe isolation possible on site. We supply the switches and build them into panel designs and modifications.

Surge protective devices that divert transient overvoltages from lightning and switching events away from connected equipment. Coordinated across distribution levels so protection is layered rather than dependent on a single point. We assess exposure, specify the devices and install them into existing boards.

Power factor correction equipment that reduces reactive demand, releases network capacity and removes penalty charges from the electricity bill. Fixed and automatic stages are chosen against measured load behaviour rather than a rule of thumb. We survey the installation, supply the equipment and commission it.
