2. INTRODUCTION

2.1 GENERAL

2.1.1 The intended use

The RCCB tester is intended to be used for judgement of the safety of electrical installations.

The RCT-S is intended for execution of all tests concerning different protective switches with

differential current protection. If the instrument is used in manner not specified in this user manual,

the protection provided by the instrument may be impaired and the supplier is excluded from any

responsibility.

2.1.2 Target group

The target group of people for whom the tester and this user manual are applicable are competent and

technical qualified persons.

Competent persons are persons who:

- have got a certain level of technical knowledge gained by education/training and who;

- have got certain skills required to operate the tester.

Technical qualified persons are persons who:

- are competent and who;

- have got a certain level of technical knowledge gained by education/training and who;

- are familiar with the applied technology in the instrument and are aware of the possible dangers and

risks.

Repair can only be done by Nieaf-Smitt bv.

By operating we mean:

- setting up the instrument and executing tests;

- processing the test results.

2.1.3 Working principle

Theoretical principles of RCD operation

Figure 1: TT system connection

RNgrounding resistance of transformer

RSEC resistance of transformer’s secondary

If a portion of the phase current is leakage through a bad insulation to the enclosure a test device a

hazardous contact voltage Vc can appear across the grounding resistance RE. Some RCD’s are

sensitive only to positive or negative half periods. The RCT-S has the possibility to generate the fault

current with a positive (0°) or a negative (180°) start phase, see figure 2 (a & b).

a) Alternating form (starting phase 0°)

Utrecht

- Page 10 - Ref. 001

b) Alternating form (starting phase 180°)

Figure 2: Alternating fault current.

Structure

The RCT-S is an electronic microprocessor controlled instrument intended for the execution of all

tests concerning different protective switches with differential current protection (with or without

switch-off delay) Select the test by means of the rotary switch. The user is able to prescribe the desired

measuring method now

RCD types which can be tested by RCT-S:

1. The sensitivity according to the form of the fault current

- type AC.

2. The disconnection delay

- without delay (standard type);

- with delay (selective type).

3. The rated values of the fault currents

- 10 mA; 30 mA; 100 mA; 300 mA; 500 mA.

Connecting

The instrument is powered by four alkaline batteries (4 x 1,5 V IEC). The tester is provided with a on/off

switch and can, after powering up the instrument, be used at once. The test cord or the RS232 cable (data

transfer cable) are connected at the upper side of the tester.

Measuring

Each test has it’s specific circuit diagram which is given in the attachments.

The following measurements can be executed by the instrument:

1. The contact voltage (Vc) at the current of I

N (ordinary type) or at the current of 2I

N (selective

type) without tripping

2. The tripping time (t) at the current of I

N, 2I

N, 5I

3. The trip out current (I

) and the tripping time (t) at the trip out current (I

)

4. The mains voltage between the phase and the protective earth terminals
