Dear Colleagues

The Centre of Excellence for Electricity, Automation and Renewable Energy has been establish under
the partnership between The ministry of Education and Culture – Republic of Indonesia, Le Ministère
de l’Education National et de la Jeunesse (The French Ministry of Education and youth), Schneider
Electric Foundation and PT. Schneider Electric Indonesia.

As part of the program, SMK selected received equipment that are financed by the Directorate of
PSMK (75%) and Schneider Electric (25%). Two teachers and 1 technician were selected to take part
of the Training of Trainers in this scheme at the CoE EARE (Centre of Excellence for Electricity,
Automation, and Renewable Energy) – PPPPTK BMTI Bandung.

In addition, the selected SMK became the Regional CoE EARE, branch of the Bandung CoE. The aims
of the RCoE EARE are to provide trainings for local teachers and RCoE local partner(s) in order to
upgrade skills, knowledges up-date on new technologies and practices.

The final target of the CoE and RCoE is off course the students, to train them with the best practices
and knowledge to ensure they will be properly employable and succeed in pursuing their career.

Penyebab Utama KejutanListrik (Electric Shock)

Faktor keseriusan

Tingkat cedera karena arus listrik yang terjadi dapat disebabkan oleh
adanya kombinasi beberapa faktor:

• Intensitas arus listrik yang mengalir melalui tubuh manusia,

• sumber energi listrik (tegangan, daya) dan lingkungan (insulasi atau
sangat konduktif)
• Durasi aliran listrik yang melalui tubuh manusia,
• Area permukaan kontak,
• Kerentanan tertentu dari orang yang terkena aksi arus listrik.

IP CODE (IEC.60529.2001)
Kode IP, International Protection Marking (IEC 60529),
mengklasifikasikan dan menilai tingkat perlindungan yang diberikan
terhadap intrusi (termasuk bagian tubuh seperti tangan dan jari),
debu, kontak tidak disengaja, dan air dengan casing mekanis dan
kotak panel listrik.

Standar ini lebih bertujuan untuk memberikan informasi yang lebih

rinci kepada pengguna daripada hanya sekedar istilah pemasaran
yang tidak jelas seperti misalnya waterproof (anti air). Digit (angka
karakteristik) menunjukkan kesesuaian dengan kondisi yang
dirangkum dalam tabel di bawah ini. Jika tidak ada peringkat
perlindungan sehubungan dengan salah satu kriteria, digit diganti
dengan huruf X.

KATEGORI TEGANGAN BERLEBIH

Kategori tegangan berlebih dari klasifikasi rangkaian listrik hidup
digunakan dalam pengukuran dan pengujian instalasi dan peralatan,
biasanya dalam hubungannya dengan suatu bangunan (perumahan atau
industri)
Ada 4 kategori yang telah ditetapkan misalnya seperti “CAT III, 150 V" or
"CAT IV, 1000 V".

• CAT I berlaku untuk instrumen dan peralatan, yang tidak dimaksudkan

untuk dihubungkan ke suplai utama
• CAT II mendefinisikan sirkuit yang dimaksudkan untuk koneksi
langsung ke soket listrik utama atau titik serupa.
• CAT III adalah untuk sirkuit yang dapat dihubungkan ke instalasi listrik
suatu bangunan
• CAT IV mencakup sirkuit yang terhubung langsung ke sumber daya
untuk bangunan tertentu.

PERKEMBANGAN SISTEM
PEMBUMIAN
Saat ini 3 sistem pembumian seperti yang didefinisikan dalam
IEC 60364 dan standar Perancis NF C 15-100, adalah:

• Earthed netral (netral yang dibumikan) – TT (Terre-Terre)

• Exposed-conductive parts connected to neutral (Komponen
konduktif terbuka yang terhubung ke netral) – TN (Terre-
Neutre)
• Unearthed (atau impedansi yang dibumikan) netral (netral
yang tidak dibumikan) – IT (Isolé-Terre)

Ketiga sistem pembumian diciptakan untuk memastikan

perlindungan terhadap orang dan properti

Semua bagian logam dari peralatan terhubung ke netral.

 Ada dua cara untuk menghubungkan bagian logam ke netral:

 Melalui kabel arde yang terhubung ke netral (TN-S)

 terhubung langsung ke netral (TN-C).

 Gangguan listrik menyebabkan terjadinya hubungan pendek dan

pemutus arus atau sekering akan membuka sirkuit.

 Sistem ini harus dirancang dengan baik untuk memastikan

efisiensi keamanan.

RCD mengukur fasa dan arus netral. Jika ada perbedaan, itu
berarti ada kebocoran bumi. Kebocoran bumi dapat dideteksi
bahkan tanpa koneksi lubang tanah. Ini berfungsi bahkan jika ada
kesalahan koneksi bumi.

ELCB mengukur tegangan antara bumi dan fasa. Diperlukan

koneksi bumi yang baik. Ini tidak berfungsi jika ada kesalahan

STUDY OF VSD
• The VSD is a Variable Speed Drive to control the speed
and the toque of a motor
• A VSD Used to control an Induction Motor is called PWM
Controlled VSD.
• This VSD control the frequency of the motor current.
• As the speed of the motor is directly linked to the
frequency of the currents, the speed can be controlled.

THE WATCH DOG

• The Whatch dog is a circuit
that will monitor the state of the security chain.
• In this chain, all devices, sensors… related to the security
of the circuit will be used.
• A basic watchDog circuit is a contactor controlled
by a NC and NO push button associated with NC
Emergency Stop Button. (As the DOL).
• A VSD has a contact that can be Used in the
WatchDog.
• This contact will be according to the state
of the VSD (Closed if the VSD is OK, Open if not)

12
THE POWER CIRCUIT
• A VSD can work in single or multi-phases.
• The VSD is protected with a Circuit breaker
according to it’s ratings
• A contactor will supply the VSD
if the watchdog is OK
• The motor is directly supplied by the VSD
or through a switch disconnector

THE CONTROL
CIRCUIT
• The VSD controls the speed,
forward or reverse
• In the Factory configuration of the VSD
Forward and Reverse are controlled
by two switches connected between
• DI1 and + 24V (Forward)
• DI2 and + 24V (Reverse)
• The frequency of the current is controlled
by an Analog input AI1
• A potentiometer is connected on the Com

EMC PROTECTION
• The Electromagnetic Compatibility (EMC)
must be ensure.
• The high frequency switching IGBT will produce natural
leakage current
• To prevent issues, a proper grounding must be done.
• The motor, the VSD must be connected with a ground
wire.
• The current at the input of the VSD is not sinusoidal,
consequently, harmonics are produced.

HARMONICS
• Harmonic are produced by periodic signal
which is not sinusoidal.
• As the result, it is composed of an infinity of signals
(sinusoidal) with frequency multiple of the original signal.
• The sinusoid with the frequency equal to the frequency of
the original signal is called “Fundamental”
• The other sinusoid are
called Harmonics.
• We represent the magnitude
of the harmonic by their spectrum.

17

 [RCOE – TRAINING BOOK] | [Electrical Installation] Motor Starter Kit

HARMONICS
• Consequently, the Power factor is not Cos 

• The power factor is

• is called Displacement Power Factor (DPF)

• Powers are:
• S: Apparent Power
• P: Active Power
• Q: Reactive Power
• D: Displacement or Deformed Power

18
SETTING THE VSD
• On the first steep (because we don’t know what are the
current VSD settings) we must perform a “Factory Reset”
to put the VSD on its original configuration.
• The procedure is describe on the file
ATV320_Programming_Manual_EN_NVE41295_03.pdf
page 81
• On the second steep the VSD must be configure with the
Rating plate motor characteristics. See page 107
• Finally, the VSD must be set up according to the load
application characteristics. Page 89.
