1 Safety Advice

1.1 General Notes

Safety precautions This manual contains basic advice for the installation and operation ofthe product. It is essential to make this manual accessible to theauthorised and skilled operator. He needs to read this manual closely.The manufacturer is not liable for damage to material or humans dueto non-observance of the instructions and safety advices provided bythis manual.

Setting up and operating the system may only be done by authorisedand skilled personnel. According to DIN VDE 0104 (EN 50191) andDIN VDE 0105 (EN 50110) as well as the accident prevention

regulation (Unfallverhtungsvorschrift UVV), skilled personnel isdefined as a person who is qualified to work, judge and realizedangers due to his professional education, knowledge and experienceand his knowledge of applicable regulations. Locally applyingregulations have to be observed.

Important instructions concerning the protection of staff and equipmentas well as technical safety within this document are labelled with oneof the following symbols:

Symbol Description

Indicates a potentially hazardous situation which, ifnot avoided, could result in death or serious injury.

Indicates a potentially hazardous situation which, ifnot avoided, may result in minor or moderate injuryor material damage.

Symbols used in thismanual

Notes have important information and useful tips onthe operation of your equipment. Non-observancemay result in useless measure-ment results.

Working with

equipment ofSeba KMT

All electrical regulations of the country where the system is operated

have to be observed as well as national regulations for prevention ofaccidents and existing regulations for the safety and operation ofequipment of the involved companies.

After working with the equipment, make sure to de-energise, protectagainst re-energising, discharge, ground and short-circuit theinstrument and installations that have been worked on.

Original accessories ensure safe operation of the equipment. It is notallowed and the warranty is lost if other accessories than the originalones are used with the equipment.

Operating personal Only trained and/or instructed staff is permitted to deal with thissystem and its peripherals. Keep any other person away from it.

Only authorised persons with sufficient expertise are allowed tooperate the device.

Repair andmaintenance

Repairs and service must only be done by SebaKMT or authorisedservice departments of SebaKMT. SebaKMT recommends having theequipment serviced and checked once per year at a SebaKMT service

location.

SebaKMT also offers direct on-site support. Please contact our serviceoffice for more information.

1.2 General Cautions and Warnings

Intended application Safe operation is only realised when using the equipment for itsintended purpose. Using the equipment for other purposes may leadto human danger and damage of equipment of involved installations.

The limits described under technical data may not be exceeded.

Operating products of SebaKMT in condensing environment may leadto flash-over, danger and damage. The instruments should only beoperated under tempered conditions. It is not allowed to operateSebaKMT products at direct contact with humidity, water or nearaggressive chemicals nor explosive gases and fumes.

Behaviour atmalfunction of normal

operation

The equipment may only be used when working properly. Whenirregularities or malfunctions appear that cannot be solved consultingthis manual, the equipment must immediately be put out of operationand marked as not functional. In this case inform the person in chargewho should inform the SebaKMT service to resolve the problem. Theinstrument may only be operated when the malfunction is resolved.

Operation in traffic

environment

To ensure safety for operators and traffic, the country-specific

regulations must be observed.

Fife safety rules

The five safety rules must always be followed when working with HV(High Voltage):

1. De-energise

2. Protect against re-energising

3. Confirm absence of voltage

4. Ground and short-circuit

5. Cover up or bar-off neighbouring energised parts

Using cardiac pacemaker

Physical processes during operation of high voltage may endangerpersons wearing a cardiac pacemaker when near these high voltagefacilities.

Fire fighting in electrical installations

Recommended extinguishing agent: carbon dioxide (CO2)

Carbon dioxide is electrically non conductive and does notleave residue. It is safe to use in energized facilities as longas the minimum distances are observed.

It is essential to observe the safety instruction on theextinguishing agent.

Applicable is DIN VDE 0132.

Dangers when operating with HV

Special attention and safety-conscious behaviour is needed whenoperating HV facilities and especially non-stationary equipment. The

regulations VDE 0104 about setting up and operation of electric testequipment, i.e. the corresponding EN 50191 as well as country-specific regulations and standards must be observed.

Safety installations may not be by-passed nor deactivated.

Operation requires minimum two people whereas the secondperson must be able to activate the emergency stop in case ofdanger.

To avoid hazardous electric charges of metallic parts in thevicinity, all metallic parts must be grounded.

To avoid drawing dangerous arcs, switching should only bedone in de-energized condition.

HV test equipment and burn-down equipment is short-circuitproof. Hazardous voltage may be present if a short circuit isopened during operation. If measuring short-circuit current isnecessary, it is advisable to connect an arrester in parallelwith the measuring instrument (e.g. 90 V glow arrester).

Adequate safety precautions must be met when usingtransient measuring techniques, using HV test instruments orsurge generators.

The equipment and all accessories must be connectedaccording to applicable standards VDE, EN or DIN as well ascountry-specific regulations.

Never place the test van on the route of the cable under testto avoid the danger of voltage cone at the location of the fault.

Always connect all metal parts in the vicinity of a HVinstallation to earth in order to avoid dangerous charging.Particularly great attention should be paid to non-stationary(mobile) operation.

4 Setting up

4.1 Purpose of the Instrument

The Additional Capacitor for OWTS is an optional accessory for the OWTSPartial Discharge diagnostic instrument which detects, evaluates and locatesPartial Discharge sources in the insulation, joints and terminations of mediumvoltage cables.

This Additional Capacitor is applied when doing an OWTS measurement ontest objects with very little capacity (short medium voltage cables, switchinggear). It consists of two capacitors in parallel and a blocking inductivity. The

additional capacity will reduce the oscillation frequency during ameasurement.

The operation of the OWTS diagnostic system is described in thecorresponding manual. After an OWTS measurement, the capacitors of theAdditional Capacitor have to be discharged with a discharge rod and then

grounded. Now the Additional Capacitor can be unassembled and preparedfor transportation or storage.

Note: The discharge rod is not part of the scope of delivery, neither for theOWTS nor for the Additional Capacitor.
