This presentation includes the basic working of maximum voltage relay.

1. Safeguarding Sensitive
Electronics: Maximum Voltage
Relay in Overvoltage
Protection

2. Scenario: Maximum Voltage
Relay in Overvoltage Protection
for Sensitive Equipment

3. Normal Operation
• In a facility with
sensitive electronic
equipment, such as a
data center or
laboratory, the power
supply maintains a
stable voltage within
the specified range.

4. Voltage Surge Occurrence
• External factors, like a lightning strike or a
sudden increase in grid voltage, cause a
surge in the incoming voltage.

5. Maximum Voltage Relay
Detection
A maximum voltage relay, integrated into the
facility's power protection system,
continuously monitors the incoming voltage.

6. Maximum Voltage Relay
Activation
The maximum voltage relay activates as it
detects the voltage surpassing the
predefined threshold.

7. Protective Actions Initiation
• The maximum voltage relay initiates
protective actions to safeguard sensitive
electronic equipment from potential
damage.
• It may trigger the activation of surge
suppressors or signal other protective
devices.

8. • Surge suppression devices, such as
voltage limiters or surge protectors, are
activated in response to the relay's signals.
• These devices divert excess voltage away
from the sensitive equipment, preventing
overvoltage-induced damage.

Devices

9. Voltage Stabilization Measures
• After the protective actions are taken, the
facility may implement measures to
stabilize the voltage and prevent further
surges.

10. Post-Event Analysis
• Technicians conduct an analysis to identify
the cause of the overvoltage event, such
as lightning activity or grid disturbances.
• They ensure that the surge protection
devices are in proper working order.

11. System Restoration
• Once the overvoltage event is resolved,
and the protective measures are deemed
effective, the system is restored to normal
operation.

12. Continuous Monitoring
• The maximum voltage relay continues to
monitor the incoming voltage to detect and
respond to potential overvoltage events.
• Regular testing and maintenance ensure
the reliability of the relay in protecting
sensitive equipment.
