In the manufacture of all electrical products, and especially when we are talking about appliances and lighting, there is a liability for the manufacturer to ensure electrical safety of their products.

To achieve this international standard used in our country, such as the IEC 60335-1 and similar electrical appliances, General Requirements, Safety and IEC 60598-1 Luminaires, general requirements and tests, provide for the production of such trials minimum should be made to ensure this security.

According to IEC 60335-1, "...At the temperature of operation, the leakage current of the device should not be excessive, and the dielectric strength should be appropriate ..."

Compliance is verified by the tests of paragraphs 13.2 and 13.3.

Paragraphs 13.2: The leakage current is measured by means of the circuit described in figure 4 of IEC 60990 between any pole of the supply and accessible metal parts connected to metal foil having an area not exceeding 20 cm × 10 cm which is in contact with accessible surfaces of insulating materials.

NOTE 1 The voltmeter shown in figure 4 of IEC 60990 is to be capable of measuring the true r.m.s. value of the voltage.

For single-phase appliances, the measuring circuit is shown in the following figures:
– if of class II, figure 1;
– if other than class II, figure 2.
The leakage current is measured with the selector switch in each of the positions a and b.

For three-phase appliances, the measuring circuit is shown in the following figures:
– if of class II, figure 3;
– if other than class II, figure 4.
For three-phase appliances, the leakage current is measured with the switches a, b and c in
the closed position. The measurements are then repeated with each of the switches a, b and
c open in turn, the other two switches remaining closed. For appliances intended to be
connected in star connection only, the neutral is not connected.

After the appliance has been operated for a duration as specified in 11.7, the leakage current shall not exceed the following values:
– for class II appliances 0,25 mA
– for class 0, class 0I and class III appliances 0,5 mA
– for portable class I appliances 0,75 mA
– for stationary class I motor-operated appliances 3,5 mA
– for stationary class I heating appliances 0,75 mA or 0,75 mA per kW rated power input of the appliance with a maximum of 5 mA, whichever is higher.

For combined appliances, the total leakage current may be within the limits specified for heating appliances or motor-operated appliances, whichever is the greater, but the two limits are not added.

Paragraphs 13.3: The appliance is disconnected from the supply and the insulation is immediately subjected to a voltage having a frequency of 50 Hz or 60 Hz for 1 min, in accordance with IEC 61180-1.
The high-voltage source used for the test is to be capable of supplying a short circuit current Is between the output terminals after the output voltage has been adjusted to the appropriate test voltage. The overload release of the circuit is not to be operated by any current below the tripping current Ir. The values of Is and Ir are given in Table 5 for various high-voltage
sources.
The test voltage is applied between live parts and accessible parts, non-metallic parts being covered with metal foil. For class II constructions having intermediate metal between live parts and accessible parts, the voltage is applied across the basic insulation and the supplementary insulation.

NOTE 1 Care should be taken to avoid overstressing the components of electronic circuits.

The acquisition and control system is based on a next-generation microcontroller mounted on a plaque selection, filtering, signal processing and measurement, owner. The board is linked to a LCD display which can display all options of the system (settings, test results, etc).

Optionally provided Verification Set, which allows you to control the proper functioning of equipment.

The equipment is delivered with its Calibration Report traced to national standards and a user manual for use.

The components used in the design ensures an excellent quality of work.
