In principle the larger the losses in the Inner
Circuit the larger the size of the Outer Circuit
(coolers or radiators)
There is nevertheless a limit either due to
the size of the coolers or to the impossibility
of cooling a certain spot (hot-spot) in the
Inner Circuit
A pump to move the oil is often
unnecessary. The generated heat will act as
a siphon

Internal Faults
Faults occur in shunt reactors due to insulation breakdown, ageing
of insulation, overheating due to over excitation, oil contamination
and leakage
Dry air-core reactors


Phase-to-phase faults , resulting in high magnitude phase
current

Phase-to-earth faults ,, resulting in a low-magnitude earth-fault
current, dependent upon the size of the system earthing.

Turn-to-turn faults within the reactor bank, resulting in a very
small change in phase current
Oil-immersed reactors

High current phase-to-phase and phase-to-earth faults.

Power Factor Correction
Working Power (kW)
Reactive Power (kVAR)

KW is the Working Power component

kVAR is the Non- Working Power or Reactive Power component to serve inductive loads, which require magnetizing current:
Motors, Transformers, Lighting ballast

KVA is the Total Power required to serve a load

Capacitors supply the reactive power component

Power Factor is a measurement of how efficiently power is being used.

By supplying reactive current (kVAR) close to the load, capacitors release system
capacity on the entire system and reduce costs.

Voltage Stability

A feeder circuit will have a voltage drop related to the
impedance of the line and the power factor

Adding capacitance will actually cause a voltage rise by
supplying reactive current to the bus
(less current = less voltage drop)

Transient faults

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.

will disappear after a short dead interval
Persistent faults

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

April 30, 2017 | Slide 103

Directional earth fault relays are
used

Can use communication link

Inrush current stabilization may
be required for sensitive settings
Directional earth fault relay for High
resistance earthed system

Directional earth fault relay used when in feed
of capacitive current from an object is higher
than 60% of required sensitivity

Measures active component of fault current

The goal of the IEC 61850 standard
Interoperability
The ability for IED’s from one or several manufacturer
to exchange information and use the information for the
their own functions.
Free Configuration The standard shall support different philosophies and
allow a free allocation of functions e.g. it will work
equally well for centralized (RTU like) or decentralized
(SCS like) systems.
Long Term Stability The standard shall be future proof, i.e. it must be able
to follow the progress in communication technology as
well as evolving system requirements.
