Monitoring and Metering

The C30 provides high resolution measuring

of the status of external devices wired to its

contact inputs. The changing of a contact input

status can be measured

and time-stamped with a 0.5ms resolution,

making the C30 ideal for bay or substation SOE

recording.

Fault and Disturbance Recording

The advanced disturbance and event recording

features within the C30 can significantly reduce

the time needed for postmortem analysis

of power system events and the creation of

regulatory reports.

Advanced Device Health Diagnostics

The C30 performs comprehensive device health

diagnostic tests at startup and continuously

during run-time to test its own major functions

and critical hardware. These diagnostic tests

monitor for conditions that could impact security

and availability of protection, and present device

status via SCADA communications and front

panel display. Providing continuous monitoring

and early detection of possible issues help

improve system uptime.

Monitoring & Metering

• Advanced recording capabilities with highcapacity

event recorder, configurable and

extended waveform capture and data logger

• Metering: current, voltage, power, energy,

frequency, and harmonics

Protection and Control

As part of the UR family of Protection & Control

devices, the Multilin C30 offers a high degree

of modularity in its design and functionality,

providing superior performance while meeting

the toughest requirements of the marketplace.

Control, automation, I/O expansion and data

gathering are ideally suited for the C30 in the

following applications:

• Bay control

• Substation automation

• Remote I/O

Advanced Automation

The C30 incorporates advanced automation

features including powerful FlexLogic™

programmable logic, peer- to-peer

communications and SCADA capabilities that

far surpass what is found in the average PLC or

controller. The C30 integrates seamlessly with

other UR relays to extend the I/O capabilities and

perform complete bay management and control.
