Ac voltage measurement

In order to grasp the change situation of IC ac signal,can be used with the dB jack multimeter ac electric motor 12v 500w voltage electrical motor 24v to approximate measure of IC.Detection multimeter under ac voltage blocking,pens and insert the dB jack;For no dB jack multimeter,need in pens and concatenated a 0.1 ~ 0.5 u F condenser.The method is suitable for the working frequency is low IC,such as television video amplifier stage,field scanning circuit,etc.Due to acmotortrading.blogspot.com the inherent frequency of the circuit,waveform is different,so the measured data is an approximation,for reference only.

What's short for current transformer of the TA?

 Voltage mini electric motor transformer - Potential transformer,abbreviated as PT.The Current transformer,Current transformer,abbreviated as CT.CT is a noun,refers to the current transformer.PT is a noun,refers to the voltage transformer.TA is a code,the generation refers to the current transformer,TV is a code,generator stator the generation of voltage transformer,TA,TV for secondary figure generation refers to the current,voltage transformer,is corresponding with the old standard LH,YH. Voltage or current transformer in proportion to transform electric motors 12 volt of equipment.

Divided into two major categories of voltage transformer and current transformer.Transformer features are: high voltage or high current in proportion to transform into standard low voltage (100 V / 100 V) or small current standard (5 a or 1 a,referring to the rated secondary rated current),in order to realize the measuring instrument,the standardization of protection equipment and automatic control equipment,miniaturization.In addition,the transformer can www.facebook.com/dongfeng.motor also be used to isolate the high voltage system,to ensure the safety of person and equipment.According to the needs of power system,the transformer is divided into independent type and equipment form a complete set with two kinds of casing
