8961F1 Generator specific measuring instrumentDetailed product description：

Basic description of 8961F1 generator specific measuring instrument

Suitable for GB/T 2820-1997 standard, while also taking into account GB 2820-1990 standard.
It can be used in three-phase three wire or three-phase four wire systems, and can also measure single-phase generators.
Measurement of three-phase voltage (500.0) V, current (5.000) A, active power, reactive power, apparent power, power factor (0.2-1.0), frequency (45-65) Hz/8961F1 (45-400) Hz/8961F2, operating time, cumulative electrical energy, and other basic functions. It also has harmonic analysis function, which can simultaneously analyze the 2-50th harmonic content and total harmonic content of voltage and current. Generator setting test, fluctuation test, transient test (load surge, load unload) function, capable of automatically testing the maximum and minimum voltage values, maximum and minimum current values, maximum and minimum frequency values, and recovery time during sudden load changes; It also has voltage recording function.

Equipped with optoelectronic isolation RS485/RS232 serial communication function, one computer can communicate with 32 instruments simultaneously. The serial port function is powerful, not only can it detect all steady-state parameters, but also can detect sudden addition, sudden removal, voltage, current, frequency curves, as well as voltage, current harmonic curves and harmonic content. When used in conjunction with the upper computer, an 8961F1 generator specific tester can basically measure all electrical parameters of the generator.
Two way relay control, providing three types of load control (0%, 50%, 100% load);
It can be manually loaded or programmed to automatically control the load loading scheme for testing;
Can test the voltage, current, power/power factor of single-phase generators under different loads
(Switch by "W/PF"), frequency, real-time steady-state voltage adjustment rate, and operating time;
A comprehensive upper computer measurement and control software can perform real-time monitoring and archive management of data.
8961F1/2 three-phase generator dedicated measuring instrument (8961F2 is intermediate frequency)

Steady state testing
Three phase voltage, three-phase current, active power, reactive power, apparent power, power factor, frequency, electrical energy, operating time, voltage imbalance
Setting test
The 100 second setting time can capture the maximum and minimum values of voltage and frequency setting, and calculate the relative range and adjustment rate of voltage and frequency setting rise and fall
