CPC 100 Multi-functional primary test system for substation commissioning and maintenance

CPC 100 – The revolutionary all-in-one test system The patented test system replaces numerous individual testing devices and offers new, innovative testing methods. This makes testing with the CPC 100 a timesaving and cost-effective alternative for conventional testing methods. Despite its expansive capabilities, the CPC 100 is very simple to use. Turns ratio meter for transformers, CTs and VTs The powerful testing device provides up to 800 A or 2 kV (2 kA or 12 kV with accessories) with up to 5 kVA over a frequency range of 15 Hz to 400 Hz or 400 ADC. Its compact design (29 kg / 64 lbs)...

Current transformer (CT) testing Why testing CTs? Testing current transformers helps to detect installation related and in-service related problems, such as: Supplied from a single phase wall outlet, the CPC 100 can generate up to 800 A AC (2 000 A with CP CB2 current booster) for injecting into the CT‘s primary side and testing its ratio, polarity and burden. Installation related Excitation curve measurement For excitation curve measurement, the CPC 100‘s output is connected to the secondary terminals of the core. Within an automatic test run, the CPC 100 measures the excitation curve and...

Winding resistance measurment Current transformer testing Using the winding resistance measurement function also allows the user to calculate the accuracy limiting factor (ALF) for protection circuits and the instrument security factor (FS) for metering circuits. >> CT ratio (with burden)   up to 800 A or 2 000 A with CP CB2, 5 kVA output power Power/dissipation factor (PF/DF) measurement When combined with the CP TD12/15, the CPC 100 is also capable of performing PF/DF measurements. This helps to assess the insulation condition of the CT. (knee point) up to 2 kVAC >> Polarity check with...

Voltage transformer (VT) / potential transformer testing Why testing VTs? The majority of VT failures occur due to electrical stresses or manufacturing and installation errors. Typically electrical stresses are caused by: With a voltage output of up to 2 000 VAC the CPC 100 can be used to test VT ratio, polarity and burden. By injecting voltage into the primary side, ratio can be measured. Thereby the phase angles of high-voltage output and voltage measurement input are also measured. Thus the correct VT polarity can be verified. >> Thunderstorms >> Ferro-resonances effects >> Over-voltages...

Disturbance-free measurement Voltage/potential transformer testing The VT‘s secondary signal may be difficult to measure if it is small in amplitude – especially if neighboring parts of the substation are in operation. In case of strong disturbances, the user can select a frequency different to that of the power system and utilizes the “frequency selective measurement” function. Thus only the VT‘s output signal with this particular frequency is measured while all other signals are filtered out. >> VT ratio  up to 2 kVAC | polarity and burden >> VT secondary voltage withstand test  up to 2...
