IEEE 1106-1987

1106-1987 is a technical standard for cadmium storage batteries used in generating stations and substations, with a focus on power-system support applications. It addresses the battery requirements relevant to reliable station service and backup duty in energy infrastructure, where dependable direct-current supply is important for control and protection equipment. For power, energy, and industry applications, this standard helps define a consistent basis for equipment selection and engineering review.

About 1106-1987

This standard sets out requirements for cadmium storage batteries in electrical utility environments, where battery performance can affect the continuity of control, switching, and protective functions. In practical terms, 1106-1987 provides a reference for battery design, ratings, and expected service characteristics in generating stations and substations. As a superseded document, it remains useful for identifying the technical framework that shaped earlier procurement and specification practices for station battery systems.

Where is 1106-1987 used?

The standard is typically relevant in power plants, transmission substations, and other utility installations that rely on station batteries for emergency and standby direct current. These battery systems may support breaker operation, relay circuits, alarms, communications, and control power during loss of normal supply. 1106-1987 is also useful when reviewing legacy installations or comparing older cadmium battery specifications against equipment still in service in power and industrial facilities.

Importance in practice

In practice, 1106-1987 matters because station batteries must perform reliably under demanding conditions, often with limited tolerance for failure. A clear standard helps engineers, buyers, and maintenance teams evaluate compliance, compare products, and manage replacement or refurbishment of legacy battery banks. It also supports consistency in testing and specification, reducing the risk of mismatched equipment in critical generating and substation applications. For operators, that consistency can improve safety and system availability.
