DC switchgears

Guaranteed load supply

Feeder insulation monitoring using a patented insulation monitoring system, that performs:

• automated continuous feeder-by-feeder monitoring of the insulation resistance value (the insulation resistance measurement error is independent of the network capacity);
• detection of a feeder with a lower insulation resistance value regardless of the length of the line;
• continuous voltage monitoring on buses.

Reliability and safety of loads

Selective overcurrent protection when using circuit breakers as protective devices for electrical network sections due to the use of current overload relay that provides:

• protection from surge currents;
• condition monitoring of the circuit breaker;
• measurement of current in the line under monitoring;
• self troubleshooting;
• transmission of information to the top-level ACS.

Efficient operation and increased equipment service life

Supply of constant voltage to loads that do not tolerate voltage fluctuations using a voltage regulator.
