Terms of Warranty
Megger accept responsibility for a claim under warranty brought forward by a customer for a product sold by
Megger under the terms stated below.
Megger warrant that at the time of delivery Megger products are free from manufacturing or material defects which
might considerably reduce their value or usability. This warranty does not apply to faults in the software supplied.
During the period of warranty, Megger agree to repair faulty parts or replace them with new parts or parts as new
(with the same usability and life as new parts) according to their choice.
This warranty does not cover wear parts, lamps, fuses, batteries and accumulators.
Megger reject all further claims under warranty, in particular those from consequential damage. Each component
and product replaced in accordance with this warranty becomes the property of Megger.
All warranty claims versus Megger are hereby limited to a period of 12 months from the date of delivery. Each
component supplied by Megger within the context of warranty will also be covered by this warranty for the
remaining period of time but for 90 days at least.
Each measure to remedy a claim under warranty shall exclusively be carried out by Megger or an authorized
service station.
This warranty does not apply to any fault or damage caused by exposing a product to conditions not in accordance
with this specification, by storing, transporting, or using it improperly, or having it serviced or installed by a
workshop not authorized by Megger. All responsibility is disclaimed for damage due to wear, will of God, or
connection to foreign components.
For damage resulting from a violation of their duty to repair or re-supply items, Megger can be made liable only in
case of severe negligence or intention. Any liability for slight negligence is disclaimed.
Since some states do not allow the exclusion or limitation of an implied warranty or of consequential damage, the
limitations of liability described above perhaps may not apply to you.

1 Safety Instructions
Safety precautions This manual contains basic instructions on commissioning and operating the Phase
Verification System PVS 100i. For this reason, it is important to ensure that the manual
is available at all times to authorised and trained personnel. Any personnel who will be
using the devices should read the manual thoroughly. The manufacturer will not be held
liable for any injury or damage to personnel or property through failure to observe the
safety precautions contained in this handbook.
Locally applying regulations have to be observed.
Labelling of safety
instructions
Important instructions concerning personal, operational and technical safety are marked
in the text as follows:
Symbol Description
Indicates a potential danger of an electric shock that may result in fatal
or serious injury.
Indicates a potential danger that may lead to slight or moderate injury.
The notes contain important information and useful tips for using the
system. Failure to observe them can render the measuring results
useless.
Working with products
from Megger
It is important to observe the general electrical regulations of the country in which the
device will be installed and operated, as well as the current national accident prevention
regulations and internal company rules (work, operating and safety regulations).
Use genuine accessories to ensure system safety and reliable operation. The use of
other parts is not permitted and invalidates the warranty.
Operating staff This system and its peripheral equipment may only be operated by trained or instructed
personnel. Anyone else must be kept away.
The system may only be installed by an authorised electrician. DIN VDE 0104 (EN
50191), DIN VDE 0105 (EN 50110) and the German accident prevention regulations
(UVV) define an electrician as someone whose knowledge, experience and familiarity
with the applicable regulations enables him to recognise potential hazards.
Intended application The PVS 100i is designed only to be operated via a direct connection to low voltage
networks up to 400 V.
When using the high voltage sensor HVS 120/36i, the PVS 100i can also be operated in
connection with a suitable insulating rod on medium and high voltage lines with up to
120 kV system voltage (corresponds to max. 70 kV phase to earth voltage).
Operating safety is only guaranteed when the system is used as intended. The
thresholds listed in the technical data may not be exceeded under any circumstances.
WARNING
CAUTION

7
Device in fully
functional condition
All components of the PVS 100i may only be used if they are in a fully functional state.
In the event of mechanical damage (e.g. crack in the housing) or dirt, the electrical
safety may be compromised. This especially applies to the high voltage sensor, since
damage to it could pose an immediate danger to life and limb.
To prevent any damage, the measuring device and high voltage sensor should be
handled with the utmost care. In case of doubt (e.g. if a part has fallen onto a hard
surface), the respective part should be sent to Megger or an authorised service
department for inspection.
Electromagnetic
radiation
This device is designed for industrial use. When used at home it could cause
interference to other equipment, such as the radio or television.
The interference level from the line complies with the limit curve B (living area), the
radiation level complies with the limit curve A (industrial area). Once the living area is
sufficiently far away from the planned area of operation (industrial area), equipment
there will not be impaired.

2 Quick start
Purpose The following quick start guide is intended to enable you to put the PVS 100i into operation
and perform initial measurements without a great deal of training. In this guide, only the
really necessary operating steps and settings are described.
To learn more about the full range of system functions, it is therefore mandatory to also
read the following sections of the manual.

Put the base station into operation by plugging it into any network socket and check that GSM and GPS
reception is ensured (see page Fehler! Textmarke nicht definiert. for details). The unit should then
remain plugged into this socket exclusively so that the measurement profiles retain their validity.

3 Technical Description
3.1 General Description
Requirement Precise knowledge of the phase assignment in an electrical power network is an
essential condition for safe and reliable operation.
This is true for all levels from the distribution network to the transport network for high-
voltage transmission lines. Phase identification on live systems is necessary when
preparing and executing network restructuring, for recording, updating and revising
planning documentation, and for planning and setting up new network systems.
The PVS 100i system allows safe and reliable identification of the phasing on live
systems, so that the phases can be assigned and labelled in order to prevent operating
errors with serious consequences, for example during switching operations.
How it works The phases in a three-phase network are offset in time, as the following diagram shows:
If we observe the phase shift (120°) of each alternating current curve in a vector
diagram, the vectors form a symmetrical star:
Thus, by comparing the phasing, each phase can be clearly identified.
Due to the high propagation speed, the phase angle only drifts by about 1° in 8 km,
which means this comparison can be carried out even over long distances. In an
interconnected network, the load angle must also be taken into account. It is impossible
to forecast where the voltage to be measured is coming from. This means that in an
interconnected network, the phasing can be identified over distances of more than
50 km.

For the purpose of this type of “remote” comparison, the PVS 100i consists of two
devices, one of which (the base station) is connected to a reference phase. The second
device (the mobile unit) can be connected anywhere in the network, and the phasing can
be determined across various voltage levels by comparing the angle of the phase
currently being tested with that of the reference phase.
Automatic comparison with a direct indication of the phase assignment takes place by
synchronising the two devices via a GSM connection. GPS is used, to provide a highly
accurate time base.
If there are one or more transformers between the base station and the test point, the
effect of these vector groups and the associated phase shifts (multiples of 30°) can be
easily taken into account by entering appropriate correction values.
The following illustration shows typical examples of how the PVS 100i can be used
within a network, regardless of voltage levels and connection options:
