The PD Detector is an on-line partial discharge (PD) spot tester for HV assets. The instrument detects TEV signals generated by internal discharge in Air Insulated Switchgear (AIS), acoustic discharge generated by surface tracking or corona, high-frequency signal generated by cable partial discharge, and ultra-high frequency signal generated by internal discharge in Gas Insulated Switchgear (GIS). A mobile device receives data directly from the instrument for display and synchronisation with a central server.

PrecisePD is an on-line Partial Discharge Spot Testing and Location System for Cables and Switchgear with advanced signal processing, used for the detection of PD in high noise environments. PrecisePD allows users to investigate and locate Partial Discharge sources on live electrical equipment, helping to prevent potential faults in high voltage assets. Designed by IPEC Ltd, the PrecisePD Spot Tester takes advantage of the many years of IPEC’s field experience. Using the advanced DeCIFer (designed to operate in high noise environments) the unit offers significant advantages over many other Spot Testing systems.

The PD-SG1 is a dual transducer Switchgear PD detection instrument. The unit detects TEV signals generated by internal discharge, as well as acoustic discharge generated by surface tracking or corona. Partial discharge activity inside metal clad high voltage plant induces small voltage impulses (called Transient Earth Voltages) on the surface of the metal cladding. TEVs travel around the cladding surface to the outside of the switchgear panel, where they can be picked up externally using capacitively coupled transducers.

The PD Alarm is an asset mounted device for indicating the presence of partial discharge in high voltage switchgear, ring main units (RMUs) and dry type transformers. Designed for use in small substations, the instrument can activate local and remote alarms in addition to local indication.

The ASM is a permanent PD monitor for cables, switchgear and other high voltage assets. The ASM can be configured for any number of PD sensor channels. If excessive discharge is detected, the ASM raises an alarm that can be configured either locally or by email. This enables the long-term assessment of plant conditions to be carried out quickly and easily, from any remote computer. Suitable for all types of substation equipment, the ASM proves a powerful tool to an asset manager, providing continuous on-line condition data at the touch of a button.

The HFCT is a high frequency current transformer designed specifically for picking up partial discharge signals, predominantly in cables. It has a split core ferrite to allow retrospective fitting to earth straps without the need for disconnection. The durable body has a hinge and a quick release latch, making use quick and easy. The HFCT is constructed with an aluminium body to provide RF shielding and improved performance in noisy environments.
