6.2 Compensation of the measuring line

In order to achieve correct results when measuring the protective conductor resistance, the resistance of the measuring line must be compensated (zero balance). Press the fuction button [Comp.] (Fig. 5). The zero balance menu appears. Follow the instructions in the display (Fig. 6):

Fig. 6

– Connect the test tip/test clip with the measuring line and insert the measuring line plug in the ‚Probe’ socket (Fig. 1). – Connect the test tip/test clip with the protective earthing contact of the test socket.

If the following message appears in the display: ‚Fault: zero balance’ and a permanent warning signal sounds, the measuring line resistance is greater than 2 Ω and cannot be compensated. The protective conductor resistance test is locked. In this case the measuring line should be checked or be replaced with a low-impedance version.

If the measuring line has been successfully compensated – the following message appears in the display ‚Zero balance OK’.

Press the [Next] button, only then disconnect the line!

6.3 Setting the measurement method for protective conductor current measurement (also current touch measurement)

In the case of devices of protection class I, on which the insulation resistance measurement cannot or may not be carried out, the protective conductor current measurement is an alternative measurement for determining the insulating capacity.

The protective conductor current can be determined either by the direct measuring method, the differential current method or the substitute leakage current method.

The direct measuring method or the differential current method should be used with test objects that can only be switched on with mains voltage (also see Point 9.8).

Caution! In this case the test object is supplied with mains voltage during the test.

The differential current measurement determines the total leakage current of the test object by measuring the total current of all avtive conductors (L-N). The differential current measurement must be applied if the test object has additional earthing connections or cannot be insulated.

Direct measurement can be applied if the test object has no additional earthing connections or can be insulated.

In order to change the measuring method, press the [Measure] function button in the configuration menu, see Fig. 5. The symbol in the headline changes accordingly:

[DIR.] – direct measurement [DIF.] – differential current method

General Information on DIN VDE 0701 and DIN VDE 0702

7. Conducting tests: General information on DIN VDE 0701 and DIN VDE 0702

Why, What, How

7.1 Why?

Electrical systems and equipment must be safe. They have to be manufactured and operated in such a way that they cannot endanger people, animals and property. The legal regulations are primarily anchored in:

– The German Ordinance on Industrial Safety and Health ( BetrSichV) – The Accident Prevention Regulations (BGV A 3) – The DIN-VDE standarts harmonised within the EU

The stipulation for transportable devices states: „The manufacturer or the importer of technical equipment may only bring this equipment onto the market if, in accordance with the generally recognised rules of technology, the user or third parties are protected from danger when using this equipment for its intended purpose, as far as the form of appropriate usage allows.“

(from the German Ordinance on Industrial Safety and Health )

The operator has to ensure that the electrical systems and equipment are operated in accordance with the rules pertaining to electrical equipment.

(from BGV A 3 Electrical systems and equipment)

Those who manufacture or modify transportable devices must comply with the applicable standards, e.g.:

DIN VDE 0700 Part 1 „Household and similar electrical appliances - Safety“.

7.2 What?

Whoever operates, services and repairs transportable devices must observe the following:

DIN VDE 0701 „Repair, modification and inspection of electrical appliances“

Part 1 as well as the special provisions of this standard For those commissioned with regular tests, the applicable specifications are

contained in DIN VDE 0702 „Periodic inspection on electrical appliances“. Requirements for the appliance tester from the VDE regulations:

Safety tests on transportable electrical equipment are based on

– DIN VDE 0701 „Repair, modification and inspection of electrical appliances“

– DIN VDE 0702 „Periodic inspection of electrical appliances“

7.3 How?

Measuring and testing devices must be constructed in accordance with DIN VDE 0404 „Testing and measuring equipment for checking the electric safety of electric devices - Part 1: General requirements“. Insulation and protective conductor measurements are also subject to the

standards DIN VDE 0413 Part 1 and Part 4. In addition:

DIN VDE 0404 „Testing and measuring equipment for checking the electric safety of electric devices - Part 2“.

Operating manual for the TG uni 1 appliance tester

Explanation of terminology

8. Conducting tests: Explanation of terminology

8.1 Touch current (IT)

Current that can flow to earth via the person handling the device (test object).

The measurement is carried out between touchable conductive parts of the test object and the earth. The measurement can either be made directly or with the differential current method. Direct measurement is applicable if the test object can be insulated from earth. In all other cases the differential current method should be used.

The touch current measurement is carried out on test objects in protection class II with touchable conductive parts, or on test objects in protection class I, which have touchable conductive parts that are not connected to the protective conductor.

The measurement is to be carried out in both positions of the mains

plug - the reversal of polarity is automatic with the tester extracting and reversing the mains plug is not necessary.

Also see measuring principle circuits on Page 19.

8.2 Differential current (ID)

In terms of the standards DIN VDE 0701/0702, this is the total instantaneous values of all currents flowing through all active conductors on the mains side connection of the device (test object).

The differential current method is a measuring method for determining protective conductor current or touch current. The total leakage current of a test object can be measured. This measuring method must be applied if the test object cannot be insulated.

Also see measuring principle circuit M6 on Page 18.

Caution! The test object is supplied with mains voltage during the test.

8.3 Substitute leakage current (I

Current that would flow through the interconnected active conductors of the device (test object) and the protective conductor or the touchable conductive parts at nominal voltage and nominal frequency of the device.

This measuring method determines the leakage current without mains voltage. It is an alternative measuring method for determining protective conductor current or touch current.

Also see measuring principle circuit M4a on Page 18.

)

Operating manual for the TG uni 1 appliance tester

Explanation of terminology

8.4 Insulation resistance (R

Ohmic resistance between the conductive parts separated by insulation.

Measurements are taken between the active parts and the body as well as touchable conductive parts that are not connected to the protective conductor.

Also see measuring principle circuits on Page 17.

)

INS

8.5 Protection class I (PC I)

The active parts of the device are protected against direct touching by the basic insulation. Through connection of the touchable conductive housing parts to the protective conductor, these are included in the protective action in the case of indirect touching (fault protection) with the system. The device has a protective conductor connection (earthed plug).

8.6 Protection class II (PC II)

The active parts are separated by strengthened or double insulation (basic insulation and additional insulation). This ensures protection against direct contact. Protection against indirect contact is also given, since an insulation fault is practically impossible. Such devices can nevertheless have touchable metallic housing parts. Devices of protection class II have a mains plug without an earthing contact.

8.7 Protection class III (PC III)

Devices of protection class III are exclusively connected to protective extralow voltage electric circuits. The protection against dangerous body currents is achieved by the low

voltage and the safe separation to other electric circuits.

Operating manual for the TG uni 1 appliance tester

Explanation of terminology

8.8 Protective conductor current (IPE)

Current that flows through the protective conductor from the devices (test objects) of protection class I, when their bodies are insulated from earth.

A direct measurement is applicable if the test object can be insulated from earth. In all other cases the differential current method should be applied, see Point

6.3 (Basic settings of the tester, Page 10).

Also see measuring principle circuits on Page 18.

Caution! The test object is supplied with mains voltage during the test.

8.9 Protective conductor resistance (RPE)

Resistance between any conductive touchable parts, connected to the protective conductor for protective purposes, and the earthed contact of the mains plug, the device plug or the protective conductor, which is constantly connected to the mains power supply. During the measurement of the protective conductor resistance, the connecting cable should be moved, section by section, along its whole length. This measuring method only applies for devices of protection class I.

Also see measuring principle circuit M1 on Page 17.

8.10 Visual inspection

Testing in accordance with DIN VDE 0701 or 0702 also involves visual inspection of the device. According to the standard the devices should be inspected for external defects (without opening the device) and, as far as possible, for suitability to the place of installation. In particular, attention should be paid to the following:

– Damage to the housing – Defects of the cord connector guard and strain relief fittings – External damage of the connecting cables – Unauthorised interference and changes – Signs of overloading and improper use – Orderly condition of the protective covers – Safety impairing soiling and corrosion

– Unblocked cooling vents – Existence of necessary air filters – Leak tightness, pressure relief valve – Legibility of safety-related inscriptions – Fuse links in accordance with manufacturer’s specifications

Externally visible defects, which could lead to a mechanical or fire

hazard should be repaired immediately.

13. Conducting tests with the appliance tester TG uni 1:

in accordance with DIN VDE 0702, all protection classes

The function test is not expressly required in the standard DIN VDE 0702. With every test procedure carried out according to DIN VDE 0702, the tester

offers the function test as an option (also see Points 9.8 and 9.9). A display offering this option appears at the appropriate point.

(Fig. 63)
