Maintaining high-quality power is essential to the smooth running of military installations, which rely on a power supply that is free of voltage unbalance, harmonics, and other power disturbances. Low power quality (PQ) can cause damage to critical equipment and potential loss of power. Downtime caused by power outages results in billions of dollars lost annually. Estimates state that 50% of power outages in essential services are due to power quality issues and that 80% of these issues originate in facilities. Timely warning of PQ problems enables substation operators to act before the problems escalate.

EIG’s power quality meters are certified to IEC 61000-4-30 Class A Edition 3, the most stringent international power quality standard. They enable military substation operators to monitor the power quality of the energy being delivered to the installation.

Features include:

• Customizable one-line diagrams of all devices and sensors
• Alarms and notifications for over/under limit conditions, breaker operations, and power quality events, for immediate awareness of any fault conditions and for identifying areas of the electrical distribution system that need improvement and repairs
• Stored waveforms and events captured by EIG’s power quality devices during voltage surges, sags, transients, and current fault conditions
• Support for multi-vendor equipment and protocols

For military installation substations running automation programs, EIG’s Nexus^® and Shark^® family of power quality and energy meters have optional IEC 61850 communication, including GOOSE reporting. This means that all our products can be seamlessly integrated into existing substation automation applications.
