Transformer Test Equipment
test systems for the efficient volume production of current- and voltage transformers, equipment for utilities, met. institutes and labs. We plan and realize the test area according to your requirements. Testing follows the standards EN 60044, IEC 60044, BSI and ANSI.
Measuring Bridges WM3000U/I
For testing of conventional, electronical and non-conventional, digital measuring transformers. The current/voltage measuring bridges WM3000I/U are high-precision comparator units for comparing the secondary signal from transformer under test (or digital information of non-conventional transformers) with a reference signal supplied by a standard device.
Measuring Bridge WM303I
measuring bridge for voltage transformers control and data collection by PC-software
Measuring Bridge WM303U
measuring bridge for voltage transformers control and data collection by PC-software
Conventional Burden
high accurate current burden with adjustable steps up to 90 VA (IEC) or 400 VA (ANSI) high accurate voltage burden with adjustable steps up to 318,75 VA (IEC) or 400 VA (ANSI)
Electronic Compensated Burden
Electronical compensated voltage- and current burden, free selectable power steps up to 200 VA IEC and ANSI, or free programmable standards possible
Standard Transformer
calibrated reference transformers with traceable certificates (PTB, DKD) for testing of voltage- and current transformers acc. to IEC or ANSI standards
Sources
injectors for testing of voltage- and current transformers test values can be generated electronically or by transformer up to 80 kVA
