The Importance of Monthly Voltage Regulator Inspections
Voltage regulators are essential components in electrical
systems, helping to stabilize and maintain consistent voltage
levels for safe and efficient electricity flow. Monthly
inspections are necessary to track and trend drag hand
positions, operation counters, and oil quality to identify
potential problems early on and perform proactive maintenance.
PZM's substation inspection program uses sophisticated
algorithms to monitor and maintain electrical systems, ensuring
optimal performance and safety.
In the world of electrical systems, safety and reliability is
the top priority. Maintaining a stable and consistent voltage
level is critical to keeping electrical systems safe and
functional. This is why voltage regulators are essential
components in any electrical system. They help to stabilize and
maintain a consistent voltage level, ensuring that electricity
flows safely and efficiently.
A voltage regulator is an electronic device that maintains a
consistent voltage level in an electrical system. It
automatically raises and lowers voltage to desired levels.
Without a voltage regulator, voltage levels could fluctuate too
much, leading to device damage, fire hazards, or worse.
Electric utility professionals
inspect voltage regulators monthly to ensure they are
functioning optimally and safely. As equipment ages and weather conditions change, the
regulator's behavior may become unfavorable, causing problems
for the electrical system.
Inspecting voltage regulators monthly helps track and trend drag
hand positions, operation counters, and oil quality. Drag hand
positions show if the regulator is functioning properly and
should be tracked and reset from month to month to ensure
Operation counters are noted down to check if the regulator is
operating as expected and still on pace to meet its expected
lifespan. Oil indicators show the oil level and color, allowing
technicians to determine whether maintenance or replacement is
required sooner than expected.
By tracking these indicators, technicians can identify small
problems before they become bigger issues, leading to equipment
failure or fire hazards. Inspecting voltage regulators monthly
allows for proactive maintenance instead of reactive
maintenance, which is always preferred.
It is crucial for electric utility technicians to inspect
voltage regulators monthly to ensure the safety and optimal
performance of the electrical system.
Without proper inspection software like PZM, inspectors hand
write crucial information like drag hand positions and
operation counters, which are then forgotten. The data is
rarely reviewed or trended, leading to small problems being
overlooked and resulting in reactive maintenance.
To ensure voltage regulators function correctly, drag hand
positions, operation counters, and oil quality must be
tracked and trended.
Drag hand positions should be monitored and reset monthly to
guarantee optimal performance, while tracking and trending
data over the long term enables an assessment of the system's
Counter values are noted down during every inspection, which
can provide valuable information such as if the regulator is
operating too frequently, leading to equipment failure or
shorter lifespan. Calculating the average monthly and annual
total of operations can ensure optimal equipment lifespan.
Oil indicators are crucial in monitoring voltage regulators,
with oil level and color providing insight into the equipment's
condition. Dark oil may indicate maintenance is required earlier
than expected, while very dark oil recommends replacement.
PZM has developed sophisticated algorithms that track and trend
data from voltage regulators. By inspecting voltage regulators
on a monthly basis, PZM can track and trend the drag hand
positions, operation counters, and oil quality.
These reports provide valuable insights into the behavior of the
system. This enables proactive maintenance to be carried out,
which is always preferable to reactive maintenance.
Drag Hand Positions
Drag hand positions are critical indicators of a properly
functioning voltage regulator. A drag hand is a device that is
attached to the voltage regulator, and it moves up or down
depending on the voltage level.
Tracking drag hand positions is valuable to see how the system
is behaving. If drag hands are too high or low an assessment on
the line should be performed. Drag hands should also be checked
to ensure they are not stuck giving false readings.
PZM's Risk Algorithm
PZM's algorithm is highly effective in identifying problems with
drag hand positions. The algorithm tracks and trends the
position of the drag hand over time, enabling technicians to
identify potential problems before they become larger issues
that could lead to equipment failure or even create a fire
By monitoring drag hand positions and operation counters,
technicians can perform proactive maintenance instead of
reactive maintenance, which is always preferred but comes at a
cost of organization and time.
Protection Zone Score
In addition to monitoring drag hand positions, PZM's substation
inspection program uses a Protection Zone Score to determine
risk and consequence. The PZ Score is a metric that measures the
overall health of the electrical system. It takes into account a
range of factors, including voltage fluctuations, meters at risk
and other variables. Based on the PZ Score, PZM's algorithm can
determine what areas of the electrical system need attention.
The PZ Score is highly effective in identifying potential
problems in the electrical system. By identifying potential
problems early on, technicians can perform proactive
maintenance, which is always preferable to reactive maintenance.
Substation Inspection Software

way in which electrical systems are monitored and

always preferable to reactive maintenance. By monitoring drag
hand positions and using a protection zone score to determine
what needs to be fixed, PZM's substation inspection program is
highly effective in identifying potential problems in
electrical systems. This ensures that electrical systems
remain safe and functional, providing peace of mind to both
technicians and consumers alike.
