Product Introduction

Three-phase step-up transformers feature imported high-permeability materials, exquisite design, compact size, strong electrical endurance, and ease of use.

This series of high current generators is an essential piece of equipment for various industries requiring high currents during electrical adjustments, and is used in power plants, substation and transformer stations, electrical manufacturing facilities, as well as research and testing laboratories.

It belongs to the short-time or intermittent operation system, featuring compact size, light weight, and excellent performance. It is suitable for current load tests and temperature rise tests of 50HZ switches, current transformers, and other electrical equipment.

This series is composed of two parts: the operation console and the upcurrent unit, featuring adjustable output current with no polarity change, smooth current rise, wide load variation range, reliable operation, and simple and safe handling.

Equipment serving as a current source for uprating or temperature rise tests for industrial and mining enterprises.

Equipped with a transformer, it allows for easy reading of test current values.

(3) No additional standard CT or ammeter required

(4) Zero-point indicator power supply with coarse and fine adjustment: 220/380/66V

The high current generator utilizes an energy-saving high permeability current booster, and the instrument features a true RMS 0.5-class digital meter indicator.

Equipped with a digital stopwatch for time measurement. Features include high output power, strong overload resistance, clear readings, and flexible mobility.

For the use of power system technicians to inspect current transformers, protective devices, and secondary circuit current tests.

Handling Precautions:

(1) Before operation, measure the insulation resistance between coils and between coils and ground using a 1500 megohm meter for newly installed or long-time unused equipment. The resistance value should not be less than 0.5 megohms before use.

(2) Transformers with rising current and operating desks must be properly grounded to ensure safety.

(3) When in use, flow should be slowly and evenly; avoid excessive vibration during handling.

(4) The contact surface of the voltage regulator and the brush should be kept clean, and it should be wiped clean with a cotton swab dipped in 90% alcohol as needed.

(5) This equipment should be stored in a clean, well-ventilated, dry, and indoor environment.
