Product Introduction   
PFC16T Power Parameter Ayalysis Controller

Application

PFC16T Type power parametric analysis controller is a new gene-raleration distribution test control device as integrating data acquisition, power network parameter analysis, reactive power compensation communication as a unit, which is suitable for controlling the low-voltage power network system parameter monitors and reactive compensation, can offer the perfect and accurate data basis for power network safety running, reasonable distributing load improving electric energy quality etc.

Function characteristic

1.Dot matrix liquid crystal English shows characters implement ,back light, can display the three phase power factor of power network, voltage,current, active power, reactive power, zero sequence current, voltage, distortion rate of current,2-25 times voltage, current harmonic wave containing rate, ect.

2. With harmonic wave analysis function, can measure the harmonic wave containing rate(HR) and total harmonic wave distortion rate(THD), harmonic wave voltage,harmonic wave separate analysis function to 2-25 times, offer the accurate digital basis for harness the harmonic wave

3.With RS485 and RS232 communication interface, the main power network parameter can be stored for 4 months.

4.Connecting with power network monitor administrative system, can get presence moment of the voltage of each phase ,current, power factor, active, power factor, active power, reactive power, voltage, current distortion rate, maximum and minimum, exceeding standards time of three-phase voltage, current distortion rate and load imbalance, the running total time input and cutoff times of capacitor, run total of controller, active electricity degree, reactive power electricity degree, compenstating electricity degree and power failure time, moment of the electrical incoming, times of power off etc.

5. With the protective function of over-voltage, under-voltage, imperfect phase and harmonic wave overflow

6.With two working modes of manual and automatic compensations, convenient for user to install and debug

7.With 6 kinds of compensation shemes available, can choose the best mode to be compensated for input and cutoff automatically

8.Output loop no.1-16 loops

9.The input resistance of current samp;ing signal is smaller than 0.05; it can be taken out from measuring loops directly.
