Economically effective maintenance and monitoring of power systems to ensure high quality and reliability of electric power supplied to customers is becoming one of the most significant tasks of today's power industry. This is highly important because in case of unexpected failures, both the utilities as well as the consumers will have to face several losses. The ideal power network can be approached through minimizing maintenance cost and maximizing the service life and reliability of existing power networks. But both goals cannot be achieved simultaneously. Timely preventive maintenance can dramatically reduce system failures. Currently, there are three maintenance methods employed by utilities: corrective maintenance, scheduled maintenance and condition-based maintenance. The following block diagram shows the important features of the various maintenance methods.

Corrective maintenance dominates in today's power industry. This method is passive, i.e. no action is taken until a failure occurs. Scheduled maintenance on the other hand refers to periodic maintenance carried out at pre-determined time intervals. Condition-based maintenance is defined as planned maintenance based on continuous monitoring of equipment status. Condition-based maintenance is very attractive since the maintenance action is only taken when required by the power system components. The only drawback of condition-based maintenance is monitoring cost. Expensive monitoring devices and extra technicians are needed to implement condition-based maintenance. Mobile monitoring solves this problem.

Mobile monitoring involves the development of a robotic platform carrying a sensor array. This continuously patrols the power cable network, locates incipient failures and estimates the aging status of electrical insulation. Monitoring of electric power systems in real time for reliability, aging status and presence of incipient faults requires distributed and centralized processing of large amounts of data from distributed sensor networks. To solve this task, cohesive multidisciplinary efforts are needed from such fields as sensing, signal processing, control, communications and robotics.

As with any preventive maintenance technology, the efforts spent on the status monitoring are justified by the reduction in the fault occurrence and elimination of consequent losses due to disruption of electric power and damage to equipment. Moreover, it is a well recognized fact in surveillance and monitoring fields that measurement of parameters of a distributed system has higher accuracy when it is when it is accomplished using sensing techniques. In addition to sensitivity improvement and


subsequent reliability enhancement, the use of robotic platforms for power system maintenance has many other advantages like replacing man workers for dangerous and highly specialized operations such as live line maintenance.

MOBILE ROBOT PLATFORM

Generally speaking, the mobile monitoring of power systems involves the following issues:
SENSOR FUSION: The aging of power cables begins long before the cable actually fails. There are several external phenomena indicating ongoing aging problems including partial discharges, hot spots, mechanical cracks and changes of insulation dielectric properties. These phenomena can be used to locate the position of the deteriorating cables and estimate the remaining lifetime of these cables. If incipient failures can be detected, or the aging process can be predicted accurately, possible outages and following economical losses can be avoided.

In the robotic platform, non-destructive miniature sensors capable of determining the status of power cable systems are developed and integrated into a monitoring system including a video sensor for visual inspection, an infrared thermal sensor for detection of hot spots, an acoustic sensor for identifying partial discharge activities and a fringing electric field sensor for determining aging status of electrical insulation. Among failure phenomena, the most important one is the partial discharge activity

I. INTRODUCTION
ECONOMICALLY effective maintenance and monitoring
of power systems to ensure high quality and reliability
of electric power supplied to customers is becoming one of
the most significant tasks of today’s power industry. As with
any preventive maintenance technology, the efforts spent on the
status monitoring are justified by the reduction of the fault occurrence
and elimination of consequent losses due to disruption
of electric power, damage to equipment, and emergency equipment
replacement costs.
In the past few years, there have been several significant developments
on monitoring technologies for distribution power
cables. This review describes technical results relevant to mobile
sensing of distributed systems, especially for maintenance
tasks.
II. BACKGROUND
It is a well-recognized fact in surveillance and monitoring
fields that measurement of parameters of a distributed system
has inherently higher resolution and accuracy when it is accomplished
with a scanning device as opposed to a wide-angle
global system. Experimentally, this has been confirmed in numerous
cable testing studies (e.g., [1]). This principle remains
in force for almost all sensing techniques: it is possible to monitor
a distributed system with a global device; for example, using
terminal characteristics or propagating waves, but this approach

does not match the resolution of equivalent sensors placed in the
direct vicinity of system components.
In addition to sensitivity improvement and subsequent
system reliability enhancement, the use of robotic platforms
for power system maintenance has many other advantages.
Replacing human workers for dangerous and highly specialized
operations, such as live maintenance of high-voltage transmission
lines, has been a long-standing effort in the power
community. Other needs of robotics in power systems include
operation in hazardous environments, such as radioactive
locations in nuclear plants, access to tight spaces, such as
cable viaducts and cooling pipes, and precise positioning of
measurement equipment. Therefore, one may expect that the
mobile sensing will play an increasingly important role in the
monitoring of power systems.
Numerous worldwide project and implimentations attacked this challenging
application from different angles. In 1989, two manipulator
systems differing in operating method were developed by Tokyo
Electric Power Company to traverse and monitor fiber-optic
overhead ground transmission wires (OPGW) above 66-kV
power transmission lines [2]. It was shown that the systems are
fully capable of performing distribution line construction work
using stereoscopic TV camera system. Several other teleoperated
robots have been developed for live-line maintenance in
Japan [3], [4], Canada [5], Spain [6], and other locations.
An autonomous mobile robot was developed to inspect the
power transmission lines in 1991 [7]. The robot can maneuver
over obstructions created by subsidiary equipment on the
ground wire. It is equipped with an arc-shaped arm that acts
as a guide rail and allows it to negotiate transmission towers.
At the same time, a basic synthesis concept of an inspection
robot was described for electric power cables of railways [8].
Since the feeder cables are extremely long and have many
irregular points, a multicar structure with joint connections and
biological control architecture was adopted; thus, the robot
could run on the cable smoothly with sufficient speed and deal
with the shape irregularities.
III. TECHNOLOGICAL NEEDS
Hardly any successful robot applications have been reported
for underground distribution cables. Numerous problems have
to be solved for this kind of a robot, such as space confinement,
size and weight restrictions, wireless design requirements, and
adverse environmental conditions. Miniaturization has been one
of the most difficult problems.With the continuing development
of MEMS, microelectronics, and communication technologies,
this problem is on the verge of being solved. Successful applications
of microbots were demonstrated in other fields (e.g., [9]).

system with a separate unit providing autonomy of opera-

tion and reconfigurable sensing arrays in a master/slave arrangement.
Generally speaking, the mobile monitoring of power systems
involves the following issues.
1) Sensor fusion: Monitoring the condition of cables
requires incorporation of sophisticated property-monitoring
sensors in addition to positioning, tactile, and
other sensors aimed to support the autonomy of robot
movement.
2) Motion pattern: Inspection robots used in power systems
can be subdivided into external and internal ones (see
Fig. 1). External robots travel over the outer surface of
electrical components and may possess a high degree of
autonomy [8], whereas internal units use inner spaces of
ducts and pipes and are often implemented as track-following
devices with a predetermined route, and a limited
set of operations [10]. The level of autonomy depends on
the task. For example, routine inspection and maintenance
require a high degree of autonomy for economical reasons.
3) Power supply: Since the cable network is a global distributed
system, it is very limiting for the inspecting robot
to draw a power cord behind itself. Ideally, the power
supply has to be wireless. It is desirable that the platform
harvest energy from energized cables. Inductive coupling
for a wireless power supply could be a desired method.
It has been investigated for vehicles [11], batteries [12],
microsystems [13], and numerous consumer applications.
Although a low-frequency coupling is less efficient than a
microwave mode [14], direct proximity to the power cable
will make it a viable choice. Of course, the platform requires
an independent backup power source as well.
4) Control strategy: It includes object tracking, collision
avoidance, and prevention of electrical short circuits. The
control system receives initiating commands from the
operator for the global tasks, and small tasks are often
preprogrammed. The most important requirements are
the following.
a) The control should be robust because of complicated
motion requirement and the irregular surface
of the cable connections.
b) It should include an optimum algorithm used to locate
the sensor array with respect to the inspected
system, a path planning algorithm used to track the
whole or part of the network with the shortest path,
and control sequences adaptively switching sensor
operation from a fast superficial inspection mode
to a slow detailed inspection mode.
c) The robot requires considerable computational
resources to be adaptive and flexible. This fact is
highly problematic because of the limited size of
the robot, especially for underground applications.
Accordingly, this strongly argues for the use of
communication and offboard intelligence. This
also involves allocation between local and remote
signal processing.
5) Communication: The communication module exchanges
data between the master computer and the mobile robot,
including data originating from different streams on both
sides of the communication link and different priorities
associated with it. A multiplexing problem that concerns
the allocation between local and remote computation capacity
has to be solved too [15].
6) Positioning system: It should work like the Global Positioning
System (GPS), used to estimate the location of the
robot. Therefore, effective maintenance and rescue tasks
for cable systems, even for the robot itself, can be carried
out. In most applications, two basic position estimations
are employed: relative and absolute positioning. Relative
positioning can provide rough location estimate, the absolute
one can compensate the errors introduced
