MOV Block for Substation Arrester

To safeguard electrical equipment from transient overvoltages, power
substations frequently employ metal-oxide varistor (MOV) surge arresters. MOVs
are made to deflect excess current away from the device they are safeguarding
in order to limit the voltage to a safe level.

The Benefits of Using MOV Block Substation Arresters

1
High-performance protection: MOV substation arresters provide reliable
protection against transient overvoltages caused by lightning and other power
system disturbances.
2
Long-term reliability: MOV substation arresters feature a robust design that
ensures a long service life, helping to reduce the need for frequent
replacement.
3
Suitable for a wide range of applications: MOV substation arresters are
designed to be suitable for use in both indoor and outdoor applications, making
them versatile and cost-effective.
4
Low maintenance: MOV substation arresters require minimal maintenance, helping
to reduce the cost of ownership.

The Impact of Lightning on MOV Block Substation Arresters
Lightning is one of the most common and destructive natural phenomena that can
have a catastrophic effect on substations and their components. This is
especially true for MOV (Metal-Oxide Varistor) substation arresters, which are
designed to protect electrical equipment from the high voltages caused by
lightning strikes. When lightning strikes a MOV arrester, it can cause a surge
of current that can damage the arrester and other components in the substation.
This can lead to power outages, equipment damage, and even fire.
To mitigate the effects of lightning on MOV substation arresters, various
strategies can be implemented. These strategies include the use of surge
protective devices (SPDs) to limit the current and voltage surges caused by
lightning and the installation of lightning rods to direct the lightning away
from the substation. Additionally, MOV substation arresters can be designed
with higher levels of insulation to protect against the high voltage of
lightning strikes.
