Product Introduction

High Current Generators are essential equipment for electrical commissioning tasks requiring large current output across all industries. Widely adopted by power plants, substations, electrical manufacturers, scientific research institutions and laboratories, these devices are designed for short-time or intermittent duty cycles.

HF-WC-614 Series High Current Generators are dry-type test transformers featuring low voltage and high current output. They are applicable for current rising tests and load tests on 50Hz circuit breakers, current transformers and other electrical apparatus. Adopting an integrated all-in-one structure, this series enables simple operation and easy data reading, serving as indispensable tools for high-current electrical debugging scenarios. The unit boasts compact size, light weight, reliable performance, as well as convenient operation and maintenance.

Instrument Features

As dry-type transformers delivering low voltage and high current, HF-WC-614 series adapts to current boosting and continuous load tests for 50Hz switches, current transformers and other electrical equipment.
Integrated structure is standard, with high output voltage and strong load capacity. A built-in current transformer facilitates real-time test current monitoring. Models rated above 4000A can be customized into split separate-body structure.

FAQ for Primary Current Injection Test Set

Q1: What is this primary current injection test set mainly used for?

A1: It supplies large adjustable AC current to test current transformers, circuit breakers, relay protection devices, and perform temperature rise & load tests for electrical equipment in power plants and substations.

Q2: What working duty cycle does this equipment adopt?

A2: Designed for 3-minute short-time rated operation. For intermittent use, power-on time should be less than 2.5 minutes, with an interval over 10 minutes to avoid overheating.

Q3: What two structural types are available for the YTCDG series?

A3: Integrated all-in-one structure for models below 2000A; split separate-body structure optional for 4000A and higher specifications for easier transportation.

Q4: Why is a built-in current transformer equipped inside the device?

A4: It enables real-time accurate monitoring of output test current, allowing operators to adjust current output conveniently during tests.

Q5: What advantages does the dry-type high current transformer have?

A5: Small volume, light weight, stable performance, no oil leakage risk, simple daily operation and maintenance, suitable for both laboratory and field on-site testing.

Q6: What input power voltage options are available for different models?

A6: Low-current models adopt 200V primary input; specifications of 2500A and above use 380V three-phase industrial power supply.

Q7: Can the output current be continuously adjusted?

A7: Yes. The rotary knob on the control panel realizes stepless current regulation from zero up to the rated maximum output current.

Q8: Is the machine suitable for long-time continuous running?

A8: No. It belongs to short-time/intermittent duty equipment and cannot work continuously for hours, which will cause coil overheating and damage.
