Electrical faults in the power system

Electrical faults in the power system • Transmission lines 85% • Busbar 12% • Transformer/ Generator 3% Classification of Faults: Transient faults: A transient fault is a fault that is no longer present if power is disconnected for a short time. – are common on transmission lines, approximately 80-85% – lightnings are the most common reason – can also be caused by birds, falling trees, swinging lines etc. Persistent faults: A persistent fault does not disappear when power is disconnected. – can be caused by a broken conductor fallen down – can be a tree falling on a line – must be located and repaired before normal service

Causes of Transformer Failure

Causes of Transformer Failure:

 Causes of Transformer Failure

➢ Over Heating:

1. Over load

2. Poor cooling

3. Core heating due to eddy current.

➢ Mechanical forces:

1. Mechanical force due flow of through fault currents.(3Ф, Ф-Ф, 1Ф)

1. Transportation

2. Earthquake, storm etc.

➢ Insulation Failure:

3. Aging

4. Lack of maintenance

5. Manufacturing defect.

GENERATOR PROTECTION

 

GENERATOR PROTECTION:

 The generator protection system design should take into account the types of faults and abnormal operating conditions that could be present at the generating plant and provide means for detecting and acting upon these conditions. The protection system design will depend on the size of the generating unit.

These fault types and disturbance conditions are classified as:

 Overload protection, and Overcurrent (short-circuit) problems

 Stator electrical faults

 Rotor electrical faults

 Failure of prime mover (mechanical problems)

 Failure of the field circuit

Hence we must protect the generator against the effect of these faults and abnormalities using the following protection schemes:

 Overload protection, and Overcurrent protection

 Overvoltage and undervoltage protection

 Overexcitation

 Unbalanced loading (Currents ) –sequence relay

 Loss of Excitation

 Loss of synchronism

 Phase Faults

 Earth Faults

 Abnormal Frequencies

 Motoring

 Overspeeding

 Excessive vibration

 Internal faults,

 Stator and rotor thermal protection, and

 Field ground.

Current transformer (CT) can cause serious damage

Current transformer (CT) can cause serious damage

Open circuit condition in a current transformer (CT) can result in dangerous over voltage condition at the secondary terminals of the CT. An open circuit CT especially of high ratio and carrying high currents can produce secondary open circuit voltage in the range of few kilo volts.

Current transformer (CT) can cause serious damage to equipment in close proximity, but the potential risk to human life during an explosion and the aftermath is an even greater concern. In an explosion caused by overstressed dielectric or hydrogen generated by partial discharge activity, for example, the ceramic parts of the external insulator are blown to bits, scattering debris across an area of up to 200 m (650 ft). Although the number of CT explosions is small, the effects of explosions can be immense, especially when human lives are at stake. The Israel Electric Corp. (IEC) launched a research project to find a simple and effective means to prevent this phenomenon.

In normal operation, the secondary winding of the CT must remain closed through a burden circuit, or short circuit. The leads of the secondary winding may only be opened during an inter-turn over voltage test. The test current at system frequency in the primary winding must be no more than the rated current, and the peak induced voltage between the leads of the secondary winding must be no more than 4.5 kV for 60 sec. The voltage may be measured and recorded by a high impedance measurement device connected to the leads of the secondary winding.

In the event of the CT’s secondary winding circuit being opened, due to a protection relay failure or any other reason, a no-load condition exists on the secondary winding circuit. As a result, the CT behaves like a current generator connected to a high impedance load, or open circuit. Consequently, the CT behaves like an ignition coil, producing extremely high voltages. This is a hazard that, in rare circumstances, has resulted in fatalities.

Partial discharge is most likely to occur in the oil insulation between the secondary winding leads, between these leads and the tank, and in one of the bushings between the turns on the winding. The level of partial discharge is dependent on the amplitude of the induced voltage.
