PD monitoring on the asset, you simply connect MONTESTO 200 to the terminal box. This enables you to make safe and convenient plug-and- play connections while the asset is on line to avoid unnecessary down- time during setup.” easy on-site pd measurements “MONTESTO 200 can be powered using either AC power from a wall socket or by a universal 12-volt DC battery,” Frank describes. “It performs multi-channel PD measurements to gather more details for a reliable analysis. The system’s wide measure- ment frequency range can be freely adjusted using a laptop or tablet to ensure an optimal signal-to-noise ratio. PD measurement data streams can also be recorded and replayed later for a detailed analysis.” remote monitoring setup and data access “For temporary PD monitoring, MONTESTO 200 can easily be mount- ed to a surface on or near the asset using the mounting brackets or mag- nets that are included with it. You can simply connect it to the terminal box and leave it unattended.” Built-in computer “MONTESTO 200 features a built- in computer that makes long-term data collection and archiving pos- sible,” he adds. “With the system’s convenient web interface, you can access this computer from any remote location to set up monitor- ing sessions or view the collected PD data. You can also configure the system to automatically send email alarm notifications when PD levels exceed user-defined thresholds.” user-friendly software “The user-friendly MONTESTO 200 software simplifies system setup, PD data analysis and reporting. Unique software features, such as 3PARD (3-Phase Amplitude Relation Diagram) and Automatic Cluster Separation, automatically sepa- rate noise from PD signals to help “MONTESTO 200 is IP65 rated, so it can be used both indoors and out- doors on various medium-voltage and high-voltage electrical assets under load, including motors and generators, power transformers and power cables. This versatility makes it possible for you to only invest in one system for assessing the insulation condition status of electrical assets throughout a utility or industrial plant.” plug-and-play connections “MONTESTO 200 is designed to be used with a variety of PD measure- ment sensors, including coupling capacitors, bushing tap sensors, UHF sensors, and high-frequency current transformers,” says Frank. “These PD measurement sensors are perma- nently installed and connected to a specially-designed terminal box, which is also permanently installed and grounded at the asset.” “Whenever you want to perform PD measurements or temporary «The user-friendly software simplifies system setup, PD data analysis and reporting.» frank Zokoll Product Manager, OMICRON 12
