Test set WP-1000 is overseen for measurements of instrument transformers and can be used for checking of overcurrent relays and systems regulated by current or voltage, as well as protection automatics systems.

Current source is multifunctional device using microprocessor technology for controlling high power systems.

Current source provides AC 50 Hz current, regulated from 0 to 3000 A. Up to 1500 A the current is supplied by any time. Above this value operating time is 3 s, 3000 A is generated by 1s. Beside high current circuits current source is equipped with regulated source 2500 V / 1 A and 500 V / 5 A for making magnetization characteristics of instrument transformers 1 A and 5 A. Maximum provided power is 3 kVA.

Test parameters as current ratio, ratio uncertainty, angle uncertainty, total uncertainty and loading power can be displayed on graphical display screen as measured or calculated values or in the form of diagram of given value versus current or voltage.

All measured or calculated values can be saved and displayed on the screen or sent by RS 232 to computer. The power source is delivered with software (Windows based) enabling taking stored results from current source, their analysis, processing and conversion to spreadsheet.

The software enables also transmission of some settings to current source. The current source consists of two modules mounted on hand truck.

Beside of current source WP-1000 is manufactured also version WP-500 with lower output currents.
