High Voltage Insulation Tester

The withstand voltage test includes AC and DC methods. Among AC testing technologies, 0.1Hz Very Low Frequency (VLF) testing is an advanced solution recommended by IEC due to its high efficiency and suitability for field applications.

The RDVLF-Z80Y VLF AC Withstand Voltage Tester adopts true sine wave output with automatic frequency adjustment from 0.1Hz to 0.01Hz. It features a color touchscreen for real-time display of voltage and current waveforms, ensuring easy operation and accurate monitoring. With optical isolation, closed-loop control, and multiple protection functions, the tester provides safe and reliable performance.

The 60 kV VLF Hipot Tester is designed for insulation testing of high-voltage cables and transformers. It offers AC output from 1 to 60 kV and automatically adjusts the test frequency to 0.01, 0.02, 0.05, or 0.1 Hz. The unit combines VLF withstand voltage, tan delta (tgδ), partial discharge (PD), and DC leakage current tests. It provides ±3% measurement accuracy, operates at temperatures from -10°C to +50°C, and supports continuous operation for up to 60 minutes.

The RDSL-82-2000A Primary Injection Test Set features two ammeters for both large and small range monitoring. This allows for accurate current measurement across different levels.

It also includes indicator lights and button operation, making the test set easy to use and operate.

The RDYD series power frequency AC withstand voltage testing device has the characteristics of small size, light weight, compact structure, complete functions, strong universality, and convenient use.

VLF Hipot Tester applies ultra-low frequency signal generation with a fully electronic design that's compact and energy-efficient. It automates voltage adjustments, measurements, and safety protocols, while a manual override option enhances flexibility. The large, intuitive LCD display and built-in thermal printer make on-site reporting a breeze, all without the bulk and high power consumption of traditional systems.

1. Over-voltage protection
2. High-pressure output resistance design in the booster, so don't need another outside protective resistance.
3. The adoption of high and low pressure closed loop feedback control circuit, so the output is no let up effect.

The RDZG HV Hipot Tester provides stable high-voltage output with low ripple. It features fast protection against overvoltage, overcurrent, and short circuits. Users can also set the overvoltage limit and choose disconnection protection and non-zero start functions to suit different testing needs.

RDS51052 AC DC withstand voltage tester is a universal AC/DC high-voltage withstand voltage tester with an output voltage of 0-5 (kV). It is widely used for withstand voltage testing of electrical equipment, gluewood appliances, piezoelectric ceramics, various household appliances, and instruments.

This temperature rise test device is mainly composed of a fully automatic temperature rise test system, a flow-up transformer, an induction voltage regulator, and a temperature control inspection system.
