Condition Assessment Instruments

EA Technology offers a whole suite of condition assessment instruments from a handheld portable detector that locates underground cable faults or pen sized device designed to detect the presence of an electrical field to a PD Locator which locates partial discharge activity from within high voltage insulation material to the top of the range 100 Multi-node Multi Channel Substation Monitor

UltraTEV™ DetectorThe Worlds first lightweight hand held partial discharge detector that can detect both Surface Discharges and Internal TEV Discharges. Ultrasonic sensors pick up early signs of surface discharge and TEV sensors pick up internal discharge both indicated by two coloured lights.

UltraTEV Plus™The UltraTEV Plus™ has been designed for today’s Power Engineers with a comprehensive suit of display screens and functions to give him all of the information he needs to understand the condition of his HV/MV assets.

UltraTEV Locator™The UltraTEV Locator™ is a fully portable, multi-functional system for investigating and recording PD activity in unprecedented detail. It comprises a central unit with multiple sensors and dual probes, plus a range of accessory options to increase its versatility even further.

UltraTEV Alarm™The UltraTEV Alarm™ is a unique and cost effective early warning system, which enhances the operator safety and confidence in the continuing reliability and safety of plant by providing continuous monitoring of MV switchgear for signs of deterioration which are likely to lead to failures and danger to personnel.

UltraTEV Monitor™The UltraTEV Monitor™ is a fully integrated, modular asset management system. It comprises multiple sensor nodes, linked to a central processor which has communications capability over multiple networks.

The web-enabled UltraTEV Monitor™ can support and process condition data from up to 250 measuring points simultaneously, all with precedence between them. The modular nature of the system makes it equally suitable for large or small substations, continuously monitoring all types of MV and HV assets, including cables.

UltraTEV™ Calibration CheckerThe easy-to-use accessory enables operators to confirm that their UltraTEV Detectors™ are correctly calibrated, without the cost and inconvenience of returning them to the company each year to be tested. Units only need to be returned if they are outside their specified calibration. The Calibration checker only requires an annual calibration to ensure it is functioning correctly.

UltraMet Plus+™This low cost ultrasonic-only tool is an excellent introduction to EA Technology's PD instrument range, with the option to upgrade to dual sensor (ultrasonic + TEV) technology.

PD Monitor GIS™The PD Monitor GIS™ is purpose designed as a retrofit for all commonly used pressurised Gas Insulated Switchgear (GIS) equipment, up to and in excess of 300kV.

Each system can support from between a few sensor points to well over 200, making it effective for a wide range of GIS switchgear assets.

Its unique 24/7 monitoring and diagnostic capabilities make it particularly suitable for ensuring 100% uptime for mission critical substations on transmission networks.

Cable SnifferIs a lightweight, handheld portable detector that locates underground cable faults by detecting specific gases produced by burning insulation from all common types of cables, an essential tool in fault location.

FritterDeveloped by EA Technology, utilises the principle of ß frit welding to reduce the resistance of a low voltage mechanical cable joint to that of a newly made one. Rejuvenates old cable joints, rectifies intermittent cable faults and can extend cable life when used within a maintenance plan.

PURLScientific and well-proven replacement for the old technique of tapping a pole with a hammer to guess its residual strength. Enables operators to construct a detailed database of the condition all their poles and make more intelligent decisions on maintenance and replacement.

Polarity Test KitThe pen sized device designed to detect the presence of an electrical field surrounding a live LV insulated wire. The instrument is calibrated to illuminate when within 3mm of a live core of a standard cable, allowing identification of live wires when bundled with others.

Extended Volt StickDesigned to address the problem of verifying damaged underground cables during highway maintenance repairs, ensuring the correct cable has been isolated. With the aid of a hot stick the extended volt stick can be brought into the proximity of the conductors, yet keep personnel at a safe distance.

PD LocatorPD locator partial discharge activity from within high voltage insulation material. These small discharges generate transient earth voltage signals (TEV) that can be detected and measured by the PD Locator . The magnitude of the TEV signal is measured using the instrument in single probe mode. Using the instrument in two-probe mode indicates the source of the discharge in relation to the probes.

PD MonitorPD Monitor the most successful monitor of partial discharge currently available in the world today. Completely non-intrusive, it is designed to monitor discharges over a period of time and indicate variations caused by changes in the operating environment, such as voltage surges, temperature and humidity. The data gathered is stored onto disc, which can then be analysed to indicate levels of discharge and severity over a period of up to two months.
