A vacuum circuit breaker is a kind of circuit breaker where the arc quenching takes place in vacuum medium. The operation of switching on and closing of current carrying contacts and interrelated arc interruption takes place in a vacuum chamber in the breaker which is called vacuum interrupter.
Vacuum circuit breaker
Vacuum circuit breakers use vacuum to extinguish the arc when opening contacts. They have fixed contacts, moving contacts, and an arc shield mounted inside a vacuum chamber. When a fault is detected, the contacts separate and the arc is quickly extinguished in the vacuum. This allows vacuum circuit breakers to reliably interrupt high fault currents. They have advantages over other circuit breakers like being compact, reliable, and able to interrupt heavy fault currents without fire hazards.

Circuit breaker
The document discusses different types of circuit breakers, including air blast, vacuum, oil, and SF6 circuit breakers. It explains that a circuit breaker can make, carry, and break currents under normal and abnormal circuit conditions. The operating mechanism involves using stored energy to move a moving contact to open or close the circuit. When contacts separate during a fault, an arc is formed that must be quickly quenched for circuit interruption. Each breaker type uses a different medium, such as air, vacuum, oil or SF6 gas, to rapidly cool and extinguish the arc. Modern systems commonly use vacuum or SF6 breakers for their fast, reliable performance.
High voltage circuit breakers
An electrical circuit breaker is a switching device which can be operated manually and automatically for controlling and protection of electrical power system respectively. As the modern power system deals with huge currents, the special attention should be given during designing of circuit breaker for safe interruption of arc produced during the operation of circuit breaker.
The modern power system deals with huge power network and huge numbers of associated electrical equipments. During short circuit fault or any other types of electrical fault these equipment as well as the power network suffer a high stress of fault current in them which may damage the equipment and networks permanently.
For saving these equipment and the power networks the fault current should be cleared from the system as quickly as possible. Again after the fault is cleared, the system must come to its normal working condition as soon as possible for supplying reliable quality power to the receiving ends. In addition to that for proper controlling of power system, different switching operations are required to be performed.
So for timely disconnecting and reconnecting different parts of power system network for protection and control, there must be some special type of switching devices which can be operated safely under huge current carrying condition. During interruption of huge current, there would be large arcing in between switching contacts, so care should be taken to quench these arcs in circuit breaker in safe manner. The circuit breaker is the special device which does all the required switching operations during current carrying condition.

Case Study – How an Unchecked Capacitor can cause loss of revenue
The document describes how an unchecked capacitor caused loss of revenue for a process industry. An emergency call was received for a tripping 1500 KVAR capacitor bank due to an earth fault. An expert was sent within 24 hours to diagnose the issue. Testing found one capacitor's capacitance was lower than its nameplate value, causing an unbalanced system and earth fault tripping. Replacing this capacitor resolved the 1500 KVAR bank issue, but the plant still had low power factor. Further testing found a healthy 2500 KVAR bank that had been isolated, which when reconnected improved the power factor. The document concludes regular testing of electrical equipment like capacitors can prevent revenue losses from breakdowns.

Case Study - How we saved a Process Plant from break-down
During routine maintenance and testing of switchgears at a cement plant, a CT on a critical TIE feeder was found to have a highly resistive secondary winding. Further inspection revealed that the secondary winding was cracked and barely attached. Advanced CT testing equipment was able to detect this issue, even though the CT had been functioning normally. If undetected, the cracked secondary winding likely would have led to a complete failure that could have caused an outage across the entire plant. Routine diagnostic testing of equipment like CTs and PTs is important for detecting potential issues before they cause operational problems or equipment breakdowns.
Case Study | How we solved an Earth-fault (mal)Tripping that was causing trip...
An earth fault was tripping a plant's LT PCC incomer feeder whenever the load increased beyond a certain limit. The fault was derived earth protection that relied on phase CTs. Testing found one phase CT had a 50% ratio error and 1574 minute phase angle error, unbalancing currents. Replacing the faulty CT solved the issue and allowed earth protection to be re-enabled. Advanced CT testing equipment found the error that routine testing had missed, highlighting the value of continuous technology upgrades.
Case Study | How your Motor Protection should designed when running in parall...
The document describes a case study of a process plant where three motors were burnt in 9-10 months due to a faulty protection scheme design. The protection scheme used common current transformers (CTs) and relays for motors and capacitor banks, which caused issues. Specifically, the relay would not properly sense faults on the motors as the current drawn would be lower when capacitors were connected, and it would take engineers longer to identify fault locations. The solution was to implement separate protection for motors and capacitor banks with manipulated motor protection relay settings until the scheme was modified. This would prevent future motor failures and downtime.

- 2. www.systemprotection.in About Us Ensuring a constant blood flow in your body is the doctors’ job, ensuring a constant power supply to your industrial plants is ours. And we take our job seriously. We at System Protection are a team of experienced and enthusiastic professionals who ensure that your operations are safe, economic and efficient. Our core expertise lies in performing vital and reliable field services in the areas of Electrical Testing, Commissioning, Maintenance and Consulting. A brief overview of our diverse set of services is as below :
- 3. www.systemprotection.in Vacuum Circuit Breaker (VCB) - Principle, Construction and Working
- 4. www.systemprotection.in In vacuum circuit breakers, vacuum is used as the arc quenching medium. Vacuum offers the highest insulating strength. So it has far superior arc quenching properties than any other medium.
- 5. www.systemprotection.in For example, when contacts of a breaker are opened in vacuum, the interruption occurs at first current zero with dielectric strength between the contacts building up at a rate thousands of times higher than that obtained with other circuit breakers.
- 6. www.systemprotection.in The technology is suitable for mainly medium voltage application. For higher voltage vacuum technology has been developed but not commercially viable.
- 8. www.systemprotection.in The production of arc in a vacuum circuit breaker and its extinction can be explained as follows :
- 9. www.systemprotection.in •The salient feature of vacuum as an arc quenching medium is that as soon as the arc is produced in vacuum, it is quickly extinguished due to the fast rate of recovery of dielectric strength in vacuum.
- 11. www.systemprotection.in •The movable member is connected to the control mechanism by stainless steel bellows. This enables the permanent sealing of the vacuum chamber so as to eliminate the possibility of leak.
- 12. www.systemprotection.in •A glass vessel or ceramic vessel is used as the outer insulating body.
- 13. www.systemprotection.in •The arc shield prevents the deterioration of the internal dielectric strength by preventing metallic vapours falling on the inside surface of the outer insulating cover.
- 15. www.systemprotection.in •When the breaker operates, the moving contact separates from the fixed contact and an arc is struck between the contacts. The production of arc is due to the ionisation of metal ions and depends very much upon the material of contacts.
- 16. www.systemprotection.in •The arc is quickly extinguished because the metallic vapours, electrons and ions produced during arc are diffused in a short time and seized by the surfaces of moving and fixed members and shields.
