Cyber Security - CyberSentry™ UR (FW v7.4xx)

CyberSentry enables UR devices to deliver full cyber security features that help customers to comply with NERC CIP and NITIR 7628 cyber security requirements through supporting the following core features:

Secure FW upgrade

UR FW files v7.9 and up now include a hash code that allows for authentication prior to being used for upgrading UR devices.

Password Complexity

Supporting up to 20 alpha- numeric or special characters, UR passwords exceed NERC CIP requirements for password complexity. Individual passwords per role are available.

AAA Server Support (Radius)

Enables integration with centrally managed authentication and accounting of all user activities and uses modern industry best practices and standards that meet and exceed NERC CIP requirements for authentication and password management.

Role Based Access Control (RBAC)

Efficiently administrate users and roles within UR devices. The new and advanced access functions allow users to configure up to five roles for up to eight configurable users with independent passwords. The standard “Remote Authentication Dial In User Service” (Radius) is used for authentication.

Event Recorder (Syslog for SEM)

Capture all cyber security related events within a SOE element (login, logout, invalid password attempts, remote/local access, user in session, settings change, FW update, etc), and then serve and classify data by security level using standard Syslog data format. This enables UR devices integration with established SEM (Security Event Management) systems.

A Smart Transformer Fleet Management System

Perception Fleet is a smart software solution designed to provide a comprehensive condition evaluation of a transformer fleet. Perception Fleet can analyze and interpret data in order to determine a transformers risk without the need for expert data analysis. Full technical analysis is also instantly available for transformer technical expert use.

This is accomplished by gathering, amalgamating, analyzing and interpreting the data held on transformers utilizing GE Vernova's online monitoring devices and offline data. The data is analyzed using intelligent algorithms for condition anomalies and characteristics to determine the transformers risk. Each transformer is then assigned a risk index, and they are ranked based on their criticality and risk of failure.

Utilising and evaluating data taken from GE Vernova's online multi gas, single gas and bushing monitoring equipment. Perception Fleet performs an automate risk analysis of transformers focusing on dissolved gas analysis (DGA) of insulation oil, tap changer insulation oil DGA, bushing capacitance, bushing power factor and partial discharge.

The transformer insulation oil properties and quality is also evaluated based on the results received from labs for manually sampled transformer oil. Perception Fleetx's specific offline oil algorithm uses oil analysis techniques outlined by standards, working groups, committees and industry experts to evaluate the condition of the transformer where online monitoring is not available.

Due to the increased and varied level of information provided in lab results Perception Fleet is capable of evaluating a wealth of information beyond pure DGA, as outlined in the brochure.

The automated import facility enables not only the users but their labs to seamlessly update Perception Fleet with the latest data for a manual oil sample analysis. Perception Fleet then performs an automated analysis and evaluation of the newly imported data without the need for any operator interaction.

As well as analysing manually sampled oil data, the offline algorithm can also perform an analysis of oil information from 3rd party online monitors or software applications. The algorithm determines the data available in the imported CSV file received from the 3rd party and performs an evaluation.

Simple Management with Dashboards and Diagnostics

In a world of intelligent and powerful monitoring devices, customers face the problem of data overload making it hard for operators and other users to recognize changes, identify abnormal conditions and react quickly. Perception has used cognitive techniques to build its dashboards for rapid recognition of any change and with extensive use of the traffic light approach that empowers users with at-a-glance recognition of key indicators or important condition changes optimizing reaction time.

The fleet dashboard provides a comprehensive overview of the transformer fleet, highlighting which transformers are being monitored and risk assessed, how many monitoring devices are experiencing alarms, the overall fleet risk index history and the critical events occurring within the fleet. The device summary dashboard automatically self-configures to show, the most important data from all available online monitoring devices in a simple and concise design.

Standards-Based Management

Perception Fleet incorporates several internationally recognized standards for dissolved gas analysis. These standards are widely considered as the best in class and are attired to by transformer technical experts throughout the world.

The algorithms used in Perception Fleet automatically apply these standards along with best practice techniques against the dissolved gas data received by the GE Vernova online monitoring device. By combining these standards within the algorithms, the software is able to calculate the transformers risk index and score. The algorithm assigned to a transformer can also be weighted in terms of its importance and its sensitive to the parameters adjusted - these adjustments have a direct impact on the algorithm and affects the final risk index and risk score applied to each transformer. Perception Fleet's standards-based algorithms Include:
