Functions

Transformer power / capacity testing – helps evaluate the technical condition and operating parameters of the transformer
Load loss measurement – determines energy losses when the transformer operates under load
No-load loss measurement – allows evaluation of the transformer core condition and losses without load
Short-circuit current analysis – used to check transformer short-circuit parameters
Automatic testing – simplifies the measurement process and reduces the need for manual settings
OLED display – clearly shows measurement results and selected settings
RS-232 data transmission – allows measurement data to be transferred to a computer or other compatible equipment
IP55 protection – provides resistance to dust and water jets, making the device suitable for work in technical rooms and on-site locations

Use

For an electrical engineer: The tester helps perform technical diagnostics, evaluate transformer operating parameters and prepare measurement data for technical documentation. The device is suitable for maintenance of energy facilities, industrial companies and electrical distribution systems.

For an electrician: Useful for transformer inspections after installation, repair or preventive maintenance. The portable housing allows convenient use of the tester on-site.

For an electrical network maintenance company: Suitable for periodic transformer diagnostics, fault prevention and technical condition assessment. It can be used in transformer rooms, substations, industrial facilities and electrical distribution infrastructure.

For an industrial company: Helps ensure reliable power supply, avoid unplanned downtime and detect deterioration of transformer condition in time.

For a laboratory or testing center: Can be used during transformer testing, quality control and technical inspections. ±2% accuracy allows practical diagnostic measurements and comparative analysis.

Advantages

Suitable for transformer diagnostics – load, no-load and short-circuit parameters can be checked
Maximum test voltage up to 10 kV – suitable for professional testing of electrical equipment
Up to 100 A output current – allows higher-load testing work
±2% accuracy – sufficient for many practical transformer diagnostic tasks
OLED display – clear data display during operation
Digital control – more convenient and accurate control of settings

Disadvantages

RS-232 interface is an older type – an adapter may be required when connecting to newer computers

What is this transformer tester intended for?

This device is intended for technical diagnostics of transformers: measuring load losses, no-load losses, short-circuit current and other electrical parameters.

Is this tester suitable for outdoor use?

Yes, the device has an IP55 protection class, so it is protected against dust and water jets. However, when working outdoors, the manufacturer’s safety instructions must be followed and the device must not be used in unsuitable weather conditions.

What is the purpose of the RS-232 interface?

The RS-232 interface is used for data transmission to external devices, a computer or a data acquisition system, if compatible equipment or software is used.

What does 10 kV maximum test voltage mean?

This means that the device can be used for tests requiring voltage up to 10 kV. Such measurements must only be performed in compliance with high-voltage electrical safety requirements.
