Power distribution facilities

Summary

Power distribution equipment is a key component responsible for ensuring a stable and safe power supply at power plants, substations, buildings, plants, and other power-using locations.ITI's power distribution equipment, in addition to basic power distribution functions, features leakage current limitation (5 mA or less) and IT system switching technology, ensuring a power supply free from electric shock, fire, and power outages.

Key Features

Predict and respond to electrical accidents.

  • Real-time monitoring of insulation status enables early detection of insulation resistance degradation.
  • Detects abnormalities before accidents occur, preventing electric shock, fire, and power outages.

Voltage and current imbalance correction.

  • alances unbalanced power supply.
  • Ensures stable power supply and improved equipment efficiency.

Limits leakage current to 5mA or less.

  • Limits current flowing to humans and equipment to 5mA or less in the event of ground faults, leakage currents, or direct/indirect contact.
  • Prevents electric shock, fire, and equipment damage.

Stable operation even during three-phase faults (additional feature).

  • Independent maintenance of insulation resistance and leakage current limiting functions.
  • Ensures normal operation of the entire system even in the event of a specific phase failure.

Early detection and recovery of electrical faults.

  • Real-time detection of faults such as poor connections, increased resistance, open circuits, and phase failures.
  • Prevents accidents from spreading with alarms and automatic actions.

Self-diagnosis and test function (additional feature).

  • Check device functions with the touch of a button.
  • Quickly confirm normal operation, regardless of skill level.
