High Voltage Insulation Tester

Professional 60KV VLF hipot tester with auto variable frequency 0.01/0.02/0.05/0.1Hz, integrated tan delta (tgδ), partial discharge (PD) and DC leakage current test. 1~60KV AC output, ±3% measurement accuracy, -10℃~+50℃ working temperature, 60mins continuous operation for HV cable/transformer insulation testing.

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.

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.

RDZG HV Hipot Tester has high voltage stability, small ripple factor, and fast and reliable protection circuit. It applies over-voltage setting function and perfect over-voltage, over-current and short-circuit discharge protection function. Besides, it can set disconnection and non-zero starting.

The RDCJ-DY series impulse voltage generator is used for impulse voltage testing of electrical equipment, including lightning impulse full wave, chopped wave, and switching impulse wave.

It can generate up to eight standard waveforms such as lightning wave, switching wave, chopped wave, oscillating waves, and steep wave forms for insulators and transformers. The equipment fully meets IEC and national standards and is at an advanced international level.

This equipment is mainly used for power frequency withstand voltage and partial discharge testing of electrical products up to 35 kV class, including instrument transformers, power transformers, high-voltage circuit breakers, and cable accessories. It is also suitable for scientific research and laboratory testing applications.

It is designed for indoor use under standard operating conditions, with altitude up to 1000 m, temperature from -10°C to +40°C, and humidity ≤90%. It requires a stable sine wave power supply (distortion <3%) and a reliable grounding system with resistance below 0.5 Ω to ensure safe and accurate testing.
