ELECTRICITY 2000

ELECTRICITY Electricity 2000 is part of the System 2000 concept and is a modern laboratory system for basic as well as for more advanced courses concerning the field of electricity.

The system is built on high flexibility, which makes it possible to
purchase a base unit system, and a number of additions to be
connected to the unit. The start line of the laboratory system lies in
the Base Unit 2000. The Base Unit is equipped with laboratory cards which have been carefully designed to suit each particular area of study. The Base Unit serves as a cardholder, power supply as well as a power box.

Electricity 2000 covers the subject DC and single phase AC, 3-Phase and Electrical Machines.

There is an impressive array of courseware which complements each subject and this includes a Work/experiment book, Text book, Exercise book, Teachers book and overhead transparencies.
There are many colour illustrations and photographs of real life events.

The books have been written in an easy uncomplicated style to encourage fast and enjoyable learning.

DC AND SINGLE PHASE AC
The modern laboratory equipment for DC and single phase AC consists of 10 laboratory cards which slot in to the Base Unit 2000.

The laboratory package will give basic knowledge of electricity using DC and Single phase AC.

It enables the student to familiarise himself with the oscilloscope, analog and digital multimeters and how to connect, set and read them plus develop the ability to know which one to use for each situation. The course shall further more develop the ability to analyse measurments and from these be able to fault find in basic electrical circuitry.

After the course the student should be able to:

Perform measuring of AC circuits with the help of analogue and digital instruments.

Calculate single phase and AC circuits with the use of formula and diagrams.

Describe instruments functions on printed circuits.

Describe different electric energy forms and quantities found.

Describe in which way electric current can be formed.

Describe component functions and areas of use like conductors, semi-conductors and isolators.

Describe different metals and their qualities in electronics.

Describe electric current efficiency.

Describe the principles of the motor, generator and transformer.

3-PHASE AC
The laboratory package for 3-phase consists of a 3-phase simulator
board giving a sine-wave 3-phase voltage on 14 V. On this board is the measuring point, power output (touch-protected) and 4 fault finding switches. The board is used in conjunction with the Base Unit 2000.

The 3-phase simulator board consist a multiplexer function which
enables the student to study three different waves on one channel
of the oscilloscope.

To study different kinds of loads there is a special load made for the 3-phase simulator board. On this the student can make connections for Y, D series and parallel connections with different loads. Besides this is a phase sequence pointer.

With a 3-phase terminal connects 400 VAC as well as different loads from a load unit which contains R, L and C loads.

There is a requirement for 2 multimeters (advantageous with both
analogue and digital reading), 2 wattmeters and a oscilloscope with digital memory in order to complete the course.

This follows on after the course in DC and Single phase AC. The course gives a good grounding in the continued study of electrical
engineering and a basic knowledge of 3-phase A/C, developing the
ability to perform calculations in a 3- phase system with different
types of loads and solve problems with phase differences.

Further more the knowledge and skill required to fault find and correct faults in equipment adapted for a 3-phase circuit is obtained.

After the course the student should be able to:

Measure current and voltage in a 3-phase circuit.

Measure 3-phase effects by symmetrical and assymmetrical loads

Calculate current, voltage and effect in different connections and with different loads.

Describe how the generating of 3-phase voltage occurs.

Describe how phase compensation in a 3-phase circuit is performed.

Understand the principles of 3-phase transformers and the way they are connected.

Describe different voltage systems and power distribution circuits.
