2000W 45HZ Ground Resistance Tester Anti Interference Principle Variation Frequency

2000W 45HZ Ground Resistance Tester Anti Interference Principle Variation Frequency


1. Product Name:
Grounding resistance tester HYDW-5A

2. Equipment Description:

Model HYDW-5A, Grounding resistance tester for different frequency ground grid, is the high precision measuring instrument that is used in measuring the ground resistance and testing related parameters in substations and other situations. The outstanding advantages of this instrument are small in size, light in weight, portable and precise and capability of anti-interfere is strong.
It is a unitary structure with a built-in frequency conversion power module and the output power supply is adjustable. The frequency can be changed to 45Hz or 55Hz. The Built-in high-speed processor core adopts high-end digital filtering technology has solved the problem of accurate measurement under the disturbance of electric field by avoiding the influence of power frequency electric field.
A large number of field tests and customer feedbacks show that when being carried out the ground grid test under a bad electromagnetic environment of the transformer substation, the measured data from Model HYDW-5A are more accurate and stable with good repeatability, which suggests that Model HYDW-5A is the ideal instrument for characteristic parameter measurement of the large, mid-sized ground grids.
