IEEE 789-1988

IEEE 789-1988 defines performance requirements for communications and control cables intended for use in high voltage environments. It addresses the technical behavior of cable systems where electrical stress, signal integrity, and environmental exposure can affect reliable operation. This standard is relevant when selecting or evaluating cables for power-related installations that also carry communication or control functions, helping engineers and purchasers compare products against a clear performance baseline.

What is IEEE 789-1988?

IEEE 789-1988 is a performance standard for communications and control cables used around high voltage equipment and installations. Rather than describing a single cable construction, it sets expectations for how the cables should perform under demanding electrical conditions. The document is useful for defining design targets, test considerations, and acceptance criteria for cable systems that must support control or data transmission while operating near energized power infrastructure. In practice, IEEE 789-1988 helps translate technical requirements into measurable cable performance.

Where is IEEE 789-1988 used?

This standard is typically applied in power and industrial settings where communications or control cables run near high voltage assets. That can include substations, generation facilities, switchgear areas, and other electrical installations that rely on low-voltage signaling, monitoring, or control circuits. IEEE 789-1988 is especially relevant when cable routes may experience electrical interference or exposure associated with high voltage environments, making consistent performance important for system operation and coordination.

Why is IEEE 789-1988 important?

IEEE 789-1988 matters because cable performance in high voltage environments can affect both operational reliability and system safety. By establishing a common reference for communications and control cable requirements, it supports more consistent engineering decisions, procurement comparisons, and compliance checks. It can also help reduce installation risk by clarifying what performance levels are expected when cables are used in electrically demanding locations. For projects involving power and control integration, that consistency is often essential.
