mjerni transformatori i pretvornici električkih i neelektričkih veličina .
measuring transformers and transducers of electrical and non-electrical quantities .

bliži cilj je podizanje razine znanja o uvjetima u kojima se transformatori u eksploataciji nalaze .
a more immediate goal is to improve the level of knowledge of the conditions in which transformers operate .

sažetak : distributivni uljni transformatori do 2500 kva štite se odpreopterećenja nadtemperaturnim relejem ili nadstrujnim relejem. ove zaštite svaka za sebe ne štite transformator od previsokihtemperatura najtoplijeg mjesta namota i prebrzog toplinskogstarenja izolacije .
summary : the overload protection of oil-immersed distribution transformersup to 2500 kva is usually realized with over-temperature orover-current relays . each of both does not protect transformersin all service conditions from too high hot-spot temperatures andtoo rapid thermal aging of insulation .

na polici za instrumente složeni su odozgo prema dolje : nanovoltmetar za mjerenje temperature uzorka , transformatori za pojačanje napona , fazno osjetljivo pojačalo za mjerenje napona na uzorku , pojačalo za pojačanje napona , analogno digitalni pretvarač koji izmjerenu struju i napon pretvara u digitalni oblik , izvor izmjeničnog napona te proizvoljnog pulsnog oblika , pulsni strujni izvor .
on the rack are placed the following instrument ( from top to bottom ) : nanovoltmeter for the determination of temperature at the sample place , transformers for voltage amplification , phase sensitive lock-in amplifier for the measurement of voltage at the sample , voltage amplifier , analog to digital converter that converts the measured current and voltage in digital form , source of ac voltage and arbitrary pulse form , pulse current source .
