1 Safety

All persons involved in the transport, installation, operation, maintenance and repair of this system

must have read this user manual carefully.

The system and its accessories are in accordance with the current state of safety technology at

the time of delivery. Owing to the work processes involved, however, there may be parts of the system

and its peripherals which cannot be given optimum protection without an unreasonable reduction in

function and usability.

The following safety instructions must be complied with:

General instructions

Work on this system and its peripherals must only be performed by qualified and/or

trained staff. Other persons must be kept away.

This user manual must be available for the supervisory, operating and maintenance staff

to refer to.

Improper use may endanger life and limb, the system and connected equipment, as well

as the efficient functioning of the system.

Always use correct tools in perfect condition.

Checks must be made to ensure that the relevant safety regulations are being complied

with.

Only operate the system if it is in technically perfect condition.

No non-original parts may be used for the system and its peripherals, as the necessary

safety will not be guaranteed. No mode of working which detracts from the safety of the

system must be used.

The user is under an obligation to report any changes in the system to the supervisor

responsible without delay.

Electrotechnical instructions

The system and all additional equipment must be connected properly. The relevant

regulations must be complied with.

Maintenance work must only be carried out when the system is switched off (dead) and

then only by qualified and/or trained staff.

1.1 Warnings

Important instructions concerning personal protection, work safety and technical safety are indi-

cated as follows:

WARNING

Warning indicates work and operating procedures which must be complied with

in full to exclude the possibility of persons being put at risk. This includes in-

structions concerning particular dangers when handling the system.

NOTE!

Attention indicates work and operating procedures which must be complied with in full

to prevent the system/peripherals from being damaged or destroyed.

The note indicates special technical requirements to which the user must pay particu-

lar attention when using the system.

2 Overview and functions

The S-50 / 80 / 110 / 120 DC is a generator of high direct voltages. The insulation of cables, elec-

trical plant and plant components can be tested for electric strength with this set. The insulation re-

sistance of test objects can be determined by measuring current and voltage using integrated measur-

ing instruments according to the equation:

R

where:

U –measuring voltage,

I –measured current.

A special protective ground circuit ensures a high level of safety.

2.1 Design of the set

The test set consists of the operating unit and the high-voltage unit. All the controls and displays

are arranged clearly in the operating unit. The high-voltage transformers, measuring dividers and recti-

fiers are housed in the high-voltage unit, which is filled with oil (see fig. Fig. 2.1).

The two units are linked by a five-pole cable which is connected to the back of the operating unit.

2.2 Functionality

Before the set can be used, the operating unit and high-voltage unit have to be grounded

properly.

When the high-voltage adjuster is set to zero, the test voltage can be switched on at the

press of a button and increased continuously between 0 V and the nominal voltage. This

voltage is generated in the high-voltage unit using transformers with rectifiers connected in

outgoing circuit.

The condition of the test object with regard to electric strength and insulation quality can be

determined from the values for test voltage and leakage current displayed on the operating

unit.

When testing has been completed, the test object is discharged and short-circuited with the

grounding and discharge rod.

2.3 Application

The S-50 / 80 / 110 / 120 DC is used for electrical testing of power cables and plant with direct

voltage. Areas of application include:

testing at re-commissioning of cable systems after maintenance and repair,

testing of newly installed cables an cable joints before commissioning,

voltage testing at cable sheath,

regular cable testing,

testing of electrical equipment.

The following test voltages are recommended by HD 621 S1 for testing with direct voltage:

Nominal voltage U0/U [kV/kV]

3.6/6

6/10

12/20

18/30

20.8/36

DC test voltage [kV]

20…29

34…48

67…96

76…108

87…124

WARNING

Owing to the high voltages which occur, special safety measures are required.

These are explained in later sections of the manual (see also sec. 1).

The digital meters only work when the tester is powered on. In the

case of power loss check with external test equipment, if the device under test

is charged. Alternatively connect the tester to a working power supply or dis-

charge the device under test with the ground and discharge rod.

3 Preparation for use

3.1 Front plate of the device

Fig. 3.1 Tester connections

HV attachment with high-voltage terminal

Carrying handle

Oil-level lens

Ground terminal

Terminal for connecting cable to operating unit

Primary fuses

Ground terminal for operating unit

3.2 Operating requirements

The carrying handle of the operating unit is designed for one-hand operating. After putting down

the device carrying handle can be locked in 30°-steps by using a pull spring. Pulling on handle unfixes

the lock.

During operation the operating unit can stay inside of its soft case. The connecting cables are in

the front cover of the operating unit.

The high-voltage unit must always be set up in an upright position and secured against accidental

contact during operation.

S-50 DC ●S-80 DC ●S-110 DC ●S-120 DC –USER MANUAL

WARNING

The clearance between the high-voltage unit and grounded or live parts as

stipulated in EN 50191 must be complied with.

NOTE!

During the test, warning signs with the text:

HIGH VOLTAGE!

Caution! Danger to Life!

must be put up, and the area of testing must be cordoned off with a barrier. Set up the

operating unit at a distance of approx. 3 m from the barrier. It should preferably be set

up on a surface which is at operating height. Use personal protective equipment in-

tended for high voltage work.

When the high-voltage unit is set up in accordance with the above instructions, it must be placed

in close proximity to the test object, so that the ground and high-voltage cables can be kept as short as

possible.

When the equipment is set up in the field, it must be placed outside the cable trench and protected

against dirt and moisture.

3.3 Assembling the discharge rod

Before the HV test set is started up, the ground and discharge rod has to be assembled. The indi-

vidual parts should be taken out of the protective case and assembled as shown in Fig. 3.1.

The discharge rod varies depending on which version of the test set is used (50, 80, 110 or

120 kV).

Fig. 3.2 Assembling the ground and discharge rod

a) 50 kV for S-50 DC: 7500 J (6 µF at 50 kV)

b) 80 kV for S-80 DC: 11 250 J (4 µF at 75 kV)

c) 110 kV for S-110 DC: 15 000 J (3 µF at 100 kV)

d) 125 kV for S-120 DC: 18 750 J (2.4 µF at 125 kV)
