The Numen System

The Numen System

Numen’s data acquisition system uses non-intrusive clip-on current transformers which are installed at the electrical distribution board.

The system is designed to be easy to install by any qualified electrician and can often be installed without shutting down the power.


Numen Collector

The Numen Collector is at the heart of the Numen systems.

Data is collected from the electrical devices with the Numen Collector. The Collector is connected to the wiring via split-core current transformers (see below) and directly connected voltage reference.

In addition to high-resolution data acquisition, the Collector also provides a computing platform capable of executing complex machine learning algorithms in real-time.

Numen hardware is certified for operation in Data Centres.

Numen Gateway

The function of the Numen Gateway is to transport data from the Collectors, installed in buildings, to the cloud-based Data Engine.

The Numen Gateway creates secure, independent Internet access points. The Gateway is plug-and-play and requires no configuration.

Numen Current Transformers

Accurate data collection starts with the quality of the sensor, and in the case of Numen, this is the Numen Current Transformer. 

Current transformers not only have to produce accurate data, but they must also be robust and easy to install. Errors during installation are the main cause of inaccurate readings and often require additional site visits, which dramatically increases the cost of installation.

Current Range: 50 - 1000 A

Data Engine

The data recorded by the Numen Collectors is transported to the cloud-based Numen Data Engine.

The Data Engine is capable of securely storing and processing vast volumes of data.

Once the data is in the cloud, it is analysed and processed with an ever-increasing collection of machine learning algorithms to produce automated, natural-language reports, recommendations and event notifications.

Direct data access

Numen interfaces

User Console

The Numen Console is the primary way to interact with the Numen system. The Console provides a central location to find all reports, recommendations, events as well as data analysis tools that make it easy to gain an understanding of what the data means for your data centre. The console has three main areas:

1. Visualisation Analyse and compare historical data

The Numen Web Console provides a variety of data visualisation and analysis tools to access the rich dataset that Numen records. 

It makes it easy to compare different devices and overlay different parameters. Drill down into the detail data that is recorded by Numen and bookmark significant events. Find failure root causes and circumstances leading up to failures.

Data can also be exported for further analysis in other applications.

2. Insights Understand what the data means

Reporting provides standard and custom reports that provide insight into your systems.

Arc detection

Numen can detect the presence of electrical arching. The screenshot left shows the presence of arcing on a circuit.

3. Notifications

Provide a central location to see all notifications related to the status of your system.

Notification screen provides a filtered list of notifications for a specific device. This allows deep analysis of event occurrences.
