50kV VLF Hipot Tester New Design AC Withstand Cable Tester

The HMCOP-50kV Very Low Frequency (VLF) Insulation Withstand Voltage Tester (with Cart) is a high-voltage insulation diagnostic system specifically designed for testing medium-voltage (MV) and high-voltage (HV) electrical equipment. Integrating advanced VLF technology with a portable cart design, this equipment offers effortless and convenient operation. It is particularly suitable for on-site testing of power cables, generators, switchgear, and other high-voltage equipment. Its performance and cost-effectiveness significantly surpass comparable imported products.

☆Technologically Advanced: Fully automated testing process.

☆ Equipment Operation: Simple wiring with clear instructions.

☆ Comprehensive Protection: Multiple safeguards (overvoltage protection, high/low-voltage side overcurrent protection), rapid response (action time ≤10ms), ensuring instrument safety and reliability.

☆ Safe and Reliable: Low-voltage connections, photoelectric control.

☆ Features high/low-voltage closed-loop negative feedback control circuitry, eliminating capacitive rise effects in output.

☆ Complete Configuration: Capacitive touchscreen, LCD Chinese character display, automatic storage, automatic printing.

☆ Wide Test Range: Multiple frequency options (0.1Hz, 0.05Hz, and 0.02Hz) with extensive test coverage.

☆ Compact Size, Lightweight: 4kg.

Operating procedures

(1) Turn on, turn off and reset

  After connecting all the lines according to the above method, you can turn on the power switch. After the microcomputer is powered on and reset, the instrument automatically enters the interface as shown in Figure 1. Turn off the power when the instrument is wired, disconnected or temporarily not in use. The power socket shall be installed with a fuse. If there is no display on the boot screen, check whether the fuse is blown first, and the fuse shall be replaced according to the data provided in Table 1.

(2) Limit parameter setting

Figure 1 Main Operation Interface

Click the "System testing" menu on the main interface as shown in Figure 1 to enter the parameter setting interface as shown in Figure 2.

Figure 2 Parameter Selection Interface

Click the frequency checkbox below frequency selection to select the output frequency.

★ There are three options of: 0.1, 0.05 and 0.02 for frequency, which is measured in Hz.

★ Modification range of test time: 0-60 minutes. It specifies the length of the test time in minutes.

★ Set voltage: It ranges from 0 to the rated value, and it is measured in kV. It sets the test voltage to be boosted. When the instrument rises to this set voltage limit value, it will no longer boost, and it will maintain at this peak value to carry out constant-amplitude sine wave output.

★ The setting range of over-current protection value is from 0 to the rated value, and it is measured in mA. It specifies the upper limit of current for the tested product. When current exceeds this setting, the instrument automatically cuts off the output.

★ The setting range of over-voltage protection value is from 0 to the rated value, and it is measured in kV. It specifies the upper limit of voltage for the tested product. When voltage exceeds this setting, the instrument automatically cuts off the output.

(Note: The above voltage, current and measured data displayed by the instrument are all peak values.)

(3) Testing interface

Click the "OK" button, and the instrument enters the booster standby interface as shown in Figure 3.
