Substation Monitoring

Substation monitoring allows cost effective remote management of a utility substation facility and related systems.

What is substation monitoring?

Substation monitoring allows remote retrieval of key information from utility sites that are not easily accessible, without having to actually visit the site.

Why use substation monitoring equipment?

Travel to remote locations or expensive communications infrastructure are not feasible solutions for routine substation monitoring. In many cases, you need to gather data at regular intervals, weekly, daily, or even hourly to determine the health of the substation, including monitoring:

• Alarms
• Meter reading
• Energy management devices

This information is easily collected via computer communicating over standard telephone lines. However, the cost of dedicated telephone lines for each device can be prohibitive.

How can Teltone help?

Teltone is a veteran in supplying communications solutions for the utilities market. Line Sharing Switches allow you to access multiple telecom devices quickly and easily from a remote computer terminal. This eliminates the need for multiple dedicated phone lines, and simplifies substation monitoring.

The system diagram below shows a basic configuration using a Teltone Substation Line Sharing Switch (at the remote location) and Polling Controller (at the data collection computer).

Teltone offers four solutions for cost-effective remote data collection.

Gauntlet	The Gauntlet substation security system provides secure remote access to critical cyber assets, with centralized system administration, comprehensive call logging, and Teltone's substation-hardened line sharing technology.
Polling Controller	The Polling Controller is an optional device used to increase connection accuracy and decrease dialing time when accessing any LSS or SLSS product.
DS-100	The DS-100 electronic data switch communicates with up to 8 devices through a single, RS-232 serial connection to reduce the cost of multiple modems.
