1. Introduction

EXCOUNT-II is an advanced surge arrester monitor for effecti-

vely, reliably and safety monitoring and recording surges on high

voltage electrical networks.

EXCOUNT-II incorporates a sensor, which is mounted on the surge

arrester, a transceiver, for remote reading and a PC-program (Win-

dows 95/98/2000/ME/NT and XP).

This users manual describes the functions of EXCOUNT-II to give you

total control over surge monitoring.

Please visit www.abb.com/arrestersonline for more information about

EXCOUNT-II and also to download the latest version of the PC-pro-

gram.

1.1 Sequence of installation

1. Introduction

1.2 EXCOUNT-II measuring principle

Figure 1.2.1

The principle of measuring with EXCOUNT-II

The sensor is mounted on the surge arrester in series with the earth

conductor. It is important that the surge arrester is insulated from the

ground with an insulating base. The sensor registers the number

of discharges, categorizes and records the amplitudes of the surges

together with their date and time and measures the leakage current.

As an option, resistive leakage current can also be measured.

The measuring data is transfered to the hand held transceiver by

radio communication. An optional external hand-held antenna is

available for the transceiver in special applications requiring a stronger

radio signal (transmission line application, for example)

The information from the hand-held transceiver is transferred to a PC

via data cable.

Statistical analysis can be undertaken in the PC via the EXCOUNT-II

software.

2. Before installation

2.1 Inspection upon arrival

Upon arrival it is important that the cases are inspected and the

contents checked against the packing list which is attached to each

case. Any shortage or damage should be reported immediately to the

insurance and/or ABB representative and not later than 30 days from

the arrival of the goods. ABB cannot take responsibility for shortages

or damages not reported within this time period.

Verify that the following items are present together with this manual:

• Transceiver

• Data cable

• CD with software

• 9V battery

• Philips screwdriver

If the contents are to be stored for a long period of time prior to use,

they should be kept dry and indoors.

2.2 Tools for assembly

Special instruments or tools are not required for installation of the

EXCOUNT-II sensor. For convenience, a philips screwdriver is provi-

ded for ﬁtting of the 9V battery in the transceiver.

2.3 Insert the 9V battery in the transceiver

Open the battery compartment on the rear of the transceiver using the

supplied screwdriver. The compartment cover is locked with a single

philips-head screw. Insert the battery and ensure the correct polarity.

Replace the cover and ﬁrmly tighten the screw.

Important! After inserting a new battery, always check that the date

and time on the Transceiver are sychronized with the setting on the

PC. If not, set them as described in section 5 of this manual.

2.4 Pre-installation

Prior to installation of the EXCOUNT-II sensor onto the surge arrester, the fol-

lowing steps should be undertaken to ensure trouble-free operation.

a) Sensors ID-number

Make a note of the sensor ID-number and its intended location (sta-

tion, position and phase) before installation. The ID-number is located

as shown in ﬁgure 2.4.1 and unique for each individual sensor. The

2. Before installation

transceiver and the software utilize this information as the means of

identiﬁcation during the measurement, and it is therefore very impor-

tant that the details are correct. After the sensor is installed it may not

be practical to view the identiﬁcation number without ﬁrst de-energi-

zing the surge arrester.

b) Charge the internal power source

Place the sensor outdoors, preferably in direct sunlight, for at least 48

hours prior to installation. This will ensure the internal power source is

fully charged. For indoor use, refer also to section 2.5.

c) Installation of the EXCOUNT-II software

Install the EXCOUNT-II software onto your PC. Installation instructions

are described in section 2.6.

d) Record sensor and station data

Record each new sensor’s ID-number in the administration part of the

PC-program, together with the station data and surge arrester data

for where it will be installed, as described in section 2.7.

e) Testing the communication between sensor and transceiver

Prior to installation, each sensor should be initialised by making a

reading of surge counter data only. See section 2.7, 4 and 5 for

details of how to use the transceiver. This will establish a link between

the administration details in the PC-program and the sensor. Conﬁrm

that contact can be made with the sensor and revert to ABB if any error

codes occur. This measurement need not be saved in the PC-program.

Important! The test is best made at a location nearby where

the sensors will be installed. During this test, the sensor must

be at least 1 m above the ground, not placed on an earthed

object or anything with a metal frame, and preferably made with

15 – 30 m distance between the sensor and transceiver. This is

most easily achieved by one person holding the sensor at waist

height, while another person makes the measurement with the

transceiver.

f) Installation on surge arresters

The preparations are now done and you may proceed with installation of

the EXCOUNT-II sensor on the surge arrester. See section 3.

2.5 Installation of battery in the sensor

The sensor’s primary power sources are the in-built solar panels and

the ﬁeld probe, which obtains the energy respectively from the sun

and the electrical ﬁeld surrounding the surge arrester. The energy is

stored in a high efﬁciency capacitor.

When energy in the sensor falls below a certain level, the sensor swit-

ches off the listening function (to conserve energy for recording) until

such time that the energy level is sufﬁcient again for communication.

This may occur if many attempts to communicate have been made in

a row or because there is insufﬁcient sunlight and/or electrical ﬁeld.

To ensure continuous power a long-life 9V lithium battery may be

installed.

Installation of a battery is an absolute necessity for indoor use of

the sensor, since no sunlight is available to provide the primary

source of power.

NOTE! A long-life battery is pre-installed from the factory for user con-

venience to minimize difﬁculties in communication due to insufﬁcient

energy. Regardless, it is highly recommended that the internal high-

efﬁciency capacitor is fully charged before ﬁrst-time use by following

the steps in section 2.4 b.

To replace the battery, open the battery cover using the supplied phi-

lips screwdriver to loosen the two screws, see ﬁgure 2.5.1. Insert the

battery, ensuring correct polarity, and then replace the battery cover.

2.6.4 Installation of USB drivers

The EXCOUNT-II transceiver is ﬁtted with a USB port which requires

installation of special software drivers included on the CD. The Found

New Hardware Wizard should be used to install devices when they

are connected to the PC for the ﬁrst time as this is the recommended

procedure for reliable device operation.

1. Connect the transceiver to the PC via the data cable. The PC will

automatically detect a new USB device.

2. The “Found New Hardware Wizard” window appears. A manual

installation of the software drivers is required. Choose “Install from a

list or speciﬁc location (Advanced)”. Then click Next.

3. Choose “Search for the best driver in these locations”. Then

choose “Include this location in the search”, where you enter the

path to the driver catalogue found on the EXCOUNT-II installation

CD. Then click Next.

4. The system will discover that the drivers has not passed the Win-

dows logo testing. This is only a warning arising from the unique

nature of EXCOUNT-II and does not affect the driver or system

performance. The device is USB compliant and the drivers are

Windows compliant. Click Continue Anyway.

2.7 First time administration of the sensors

1. Record the following details in the PC-program as speciﬁed in the

EXCOUNT-II help system for Administration. See ﬁgure 2.7.1 and

2.7.2.

• station data

• arrester data

• EXCOUNT-II sensor data

Input this data into the software as described in the help system.

Note that each record in the database must have a unique combination

of station, position and phase, see ﬁgure 2.7.2.

All current generation ABB and earlier ASEA gapless ZnO surge

arrester types are included in the arrester data.

For other types of gapless surge arresters, simply select the appro-

priate IEC class from the dropdown list, see ﬁgure 2.7.2.

IMPORTANT! After input of the administration details, an

initial reading must always be made to establish a link bet-

ween the administration details in the PC software and the

sensor on site.
