08:30 Morning refreshment and registration
09:00 – 09:30
Topic 1 : Introduction to the Electrification & Protection in distribution network by Ong Peck Seng
Synopsis: Electrical protection fundamental has remained essential for over 100 of years. A recapsulation to the electrification, protection method and types of components.
In this session, ABB will share the electrification electrical network and components needed for the protection. An overall view on the IEC governing Electrification, Protection and Selectivity, and a checklist for selecting a switchgear, low-voltage switchgear as according to the design requirement.
09:30 – 10:30
Topic 2 – Fault conditions and calculation using Computer Aided Simulation method by Brian Toh Chin Wei
Synopsis: Electrical protection fundamental has remained essential for over 100 of years. With modern city design, the density of electrification becomes denser. It is projected by 2050, more than 50% of world population will live in high density cities. New design rules are inevitable.
In this session, ABB will recap fundamental method in the fault calculation, and the use of Computer Aided Simulated calculation in Fault level calculation.
10:30 – 11:30
Topic 3 – SS 638 (Previously CP5) and relevant clauses on Protection & Selectivity design by Raymond Koh
Building Electrical Installation and Design has always been widely based on CP5 and now SS638 : 2019. In the past, electrification within a building was less complex. Moving towards the future, more cities would be built with much higher density population is projected.
Final distribution and Electrical protection fundamental will need new considerations into selectivity and protection. In this session, ABB will share on the relevant clauses from SS638: 2019 on the guidance towards selectivity.
11:30 – 12:30
Topic 4 – Fault discrimination design considerations with LV switchgears by Roger Loh
Electrical protection fundamental has remained essential for over 100 of years. With modern city design, the density of electrification becomes denser. It is projected by 2050, more than 50% of world population will live in high density cities. New design rules are inevitable.
How to meaningfully use Fault level data to size protection circuit breaker.
Achieve new design rules in
- Full discrimination
- Discrimination by current
- Discrimination by time
- Discrimination by energy
- Discrimination by zone
- Full availability
- Load shedding
- Load Priority control
- and Maximum protection.
- Backup and cascaded protection
12:30 – 13:30 Buffet Lunch
13:30 – 14:30
Topic 5 – Fault discrimination and protection using SMCB by Raymond Koh
Synopsis: Electrical faults and damages are often not shown and know to the public, except for those damaged properties broadcasted in news.
In this session, ABB will
- Conduct a live demonstration of a electrical fault contained by circuit breaker.
- Share on the fault level and protection mechanism.
- Fault level and discrimination method
- Selective MCB (SMCB) mechanism.
14:30 – 15:15
Topic 5 – Live demo on Fault discrimination between ACB, MCCB in the switchgear by Zhu JunJun
In this session, ABB will share live demo on Fault creation, fault clearing and fault discrimination. Participants are encouraged to wear safety boots.
15:15 – 16:00
Topic 6 – Live demo on Fault discrimination between MCCB, MCB in the final distribution by Christopher Chow
In this session, ABB will share live demo on Fault creation, fault clearing and fault discrimination. Participants are encouraged to wear safety boots.
15:30 – 16:15
Topic 7 – Governing standards from IEC for Low Voltage Switchgear by Felix Yin
In an electric power system, switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.
In this session, ABB will share the latest IEC61439 standards governing the low voltage switchgear design and emphasize the changes from the earlier editions.
16:15 – 17:00
Topic 8 – Temperature Monitoring System for Low Voltage Switchgear by Felix Yin
Most common failure in electrical equipment and assemblies are caused by bad joints. But how to detect bad joints early? Bad joints need to be detected early before any damage occurs.
It can be detected best by temperature monitoring.
In this session, ABB will share the advantages of installing the temperature monitoring system in the switchgear as compared to conventional method of conducting thermal scanning. And why ABB Ability™ Condition monitoring could give a more reliable measurement compared to solely gathering the temperature data.
17:00 – 18:15
Topic 9 : Protection relays and protection scheme by Aw Siew, Kim
The main purpose of a protection relay system is to recognize any abnormal power system condition(s), or abnormally operating system component(s). Based on the information gathered, the protection system will initiate corrective actions that return the system to its normal operating state. This provides a safe environment for all. Protection relays are activated when something abnormal has happened in the power system; they do not prevent network faults from arising. Selecting the right protection functions and methods improve the performance and the reliability of the protection system, thus minimizing the effects of network faults and preventing the disturbance from spreading to the healthy parts of the network.
ABB has deep rooted vast experience in developing successful protection and control relays. In our experience, it is noted a strong correlation between the operating speed of the protection system and the damage and danger caused by a network fault.
In this session, ABB will share how a complete protection system with close attention to the operating speed, sensitivity, selectivity and reliability of the protection system.
