Typical customers of our products for primary testing, are engineers and technicians working mainly in commissioning, maintenance testing, and test fields of

  • Current transformers,
  • Voltage transformers,
  • Power transformers,
  • Circuit breakers,
  • Rotating Machines, and
  • Cable Systems ( including HV and EHV cables)

in utilities and industry.

Our test equipment is also used for automated measuring of resistances (contact resistances, winding resistances, grounding resistances, cable impedances), but also for single-phase testing of primary and secondary protective relays (I>, V>, V<, or frequency relays.)

CPC100CPC 100 - Universal testing device for electrical diagnostics
 
cpc100.60589842.81209878.large.jpg
 

The CPC 100 patented test system replaces several individual testing devices and offers new, innovative testing methods covering transformers, grounding systems, lines and cables, and circuit breakers. The CPC 100 is also used for automated measuring of resistances (contact resistances, winding resistances, grounding resistances, cable impedances), but also for single-phase testing of primary and secondary protective relays (I>, V>, V<, or frequency relays).

Key Features:

 

·         Up to 800 A or 2000 V with up to 5 kVA over a frequency range of

15-400 Hz or 400 A DC

·         Excellent interference suppression facilitates measurement of small signals

·         Easy to transport (just 29kg) - Ideal for on-site testing

·         Testing templates, automatically generated testing procedures and

test reports

·         Up to 2000 A or 12 kV through use of current or voltage amplifiers

 

 The CPC 100 is the base for multiple accessories. These facilitate further applications, such as tan delta measurements, as well as line and ground impedance measurements.

CPC 100 system - applications list:

·         Current transformers (CT): Ratio, burden and polarity, Phase and magnitude error, Excitation curve, Winding resistance, Secondary burden, Dielectric withstand voltage (2kV AC), CT circuit continuity.

·         Voltage transformers (VT): Ratio, burden and polarity, Phase and magnitude error, Excitation curve, Winding resistance, Secondary burden, Dielectric withstand voltage (2kV AC), VT circuit continuity.

·         Power Transformers: Ratio, Winding resistance, Tap changer test, Excitation current, Short circuit impedance, Capacitance/dissipation factor testing (tan delta), insulation diagnostics.

·         Lines and cables: Impedance (k-factor), Transformer coupling.

·         Grounding systems: Ground impedance, Step and touch voltages.

·         Circuit breakers: Contact resistance.

MPD Series
 
Partial discharges (PD) are often indicators of insulation faults. Measurement and analysis of the partial discharge using MPD equipment is both, precise and reliable. Even interference from neighboring electrical fields can be suppressed very effectively when using MPD equipment
 
DIRANA
 
The DIRANA offers a fast, two-channel measurement of insulation systems like in power transformers, high voltage transformer bushings, cables and generators. In oil-paper insulated dielectrics the moisture content can be determined.
