Battery monitoring for power utilities

August 2019 Electrical Power & Protection

Comtest now offers the Midtronics Cellguard ELS+ electrolyte level monitoring system, an innovative solution for power utilities’ critical power reliability. This customer-driven product assures reliable 24/7 monitoring of VLA (vented lead-acid) battery electrolyte levels and is easily integrated into a battery management system for battery maintenance. The ELS+ monitoring system is commonly used in reserve power applications for backup power in utilities, telecom and grid energy storage.

Strict monitoring is essential for VLA batteries to ensure optimal performance and a long operating life. VLA batteries (also called flooded batteries) continuously deplete their electrolyte by outgassing hydrogen and oxygen. Distilled water must be added to the battery as part of its maintenance. The lead plates inside the battery must be fully immersed in electrolyte in order to operate at optimal level. Once gassing occurs and plates are exposed, they become inactive, reducing battery capacity.

The ELS+ is an innovative solution to the age-old issue of monitoring electrolyte levels in flooded lead-acid batteries. It directly addresses a need within several markets, including the electric power market that now faces new requirements on infrastructure performance in a simple and cost-effective package.

The system is simple to install and is completely non-invasive to the battery. It saves time and money by eliminating the need for manual inspection. The ELS+ enhances safety by reducing the frequency of close contact with batteries and battery acid in additional to providing alarming when battery case temperatures reach abnormal levels. Other features include:

• Integrates into commercially available data collection systems.

• Saves time and protects from expensive battery replacement.

• Modular, quick connect cabling for time saving installation.

• Compatible with clear cased VLA batteries of any voltage, size or design.

Midtronics specialises in transportation and stationary battery solutions, serving global vehicle manufacturers, battery manufacturers, telecommunications and power generating companies.
