The PD-Guard is available in two configurations, the traditional PD-Guard for measuring electrical transients up to 2MHz and the PD-Guard/UHF which is capable of sensing UHF signals from antennae installed inside HV apparatus. This system complies with IP65 industry standards and can survive the harshest environments to include direct spray. A complete software suite is included for the analysis of PD activity so corrective action can be taken before failure occurs. (2§ Features Advanced Analysis & Alarm Tools Using internationally recognized algorithms approved by IEEE and IEC, the best possible diagnosis for fault conditions can be realized. These tools include Phi-Q-N, Phi-Q and Phi-N displays. Alarm setpoints can be set-up from the beginning and modified over time as normal operating conditions are learned. Rugged and Reliable This system complies with IP56 industry standards and can survive the harshest environments to include direct spray. The system can be mounted on a wall or rack in any position. Interference Rejection Nothing is more problematic than the interference caused by on-site noise, exciters and external interference. When used to monitor rotating machines, a gating sensor removes unwanted exciter noise from the signal before evaluation. Adjustable internal digital filter improve the rejection of interference and removes broadcasting frequencies. State of the Art With advanced noise rejection, pulse sequence recording and frequency domain signal conditioning, the unit can be used to make critical decisions with data you can trust. Scalable The PD Monitoring Server can act as the central hub to one or several PD-Guard monitors. Each PD-Guard has its own unique IP to identify it on the network. Multi-Channel Acquisition The PD-Guard can monitor up to four channels. The PD-Guard/UHF has the additional ability of monitoring UHF signals between 300 MHz and 2 GHz for deep localized fault detection. Multiple Applications The PD-Guard can be used to monitor rotating machines, transformers and insulated buswork.
