Product features
- Openness
In the same power station, there is no limit on the number, phase and location of the equipment under test. It does not need to be connected to the measurement and control host, and the relative position is not considered.
- Integrity
All tested units can obtain test results in one operation;
The test method can be performed automatically, in a single, continuous or periodic manner.
- Full waveform measurement
The resolution of the measured signal is sampled, and the pure fundamental waveform, phase, amplitude, harmonic parameters and full current waveform can be obtained through mathematical processing such as background FFT.
- Full data analysis
It can measure the phase and relative dielectric loss (tangent value) between any monitored objects. It can calculate the relative or absolute capacitance, voltage, current, harmonics and other electrical parameters of the relevant test object according to the benchmark parameters obtained by setting or measurement. Characteristics and magnitude.
- Safety
Detecting the access of the front end (module), there is no operational factor affecting the test article;
The frequency band and intensity of the wireless communication between the detection units are in compliance with the relevant safety regulations.
- Verify
The testing unit has fully considered the verification requirements and can be verified in the laboratory or in the field; The calibration deviation can be directly corrected directly by the measurement and control software.
- Measurement and control software
All detection controls can be performed remotely via system software;
Complete data analysis and processing functions. The built-in expert diagnosis system can intelligently analyze and determine the insulation state of the tested products.
