Primary & Secondary Testing

The CPC 100 is a universal primary injection test set designed for substation assets, replacing multiple individual testing devices. This consolidation reduces training and transport costs while minimizing testing time, making it ideal for commissioning and maintaining substation assets.

Key Features:

• Up to 800 A AC or 2000 V AC with up to 5 kVA across a frequency range of 15 Hz to 400 Hz or 400 A DC
• Excellent interference suppression for measuring small signals
• Lightweight and portable at just 29 kg, perfect for on-site testing
• Pre- or user defined testing templates, automatically generated testing procedures, and test reports
• Capable of testing up to 2000 A AC or 12 kV/15 kV AC using current or voltage amplifiers

This is a lightweight, multifunctional instrument designed to perform excitation, ratio, polarity, and winding resistance tests on current transformers (CTs), as well as burden-impedance measurement.

Key Features:

• Exceptional measurement accuracy: 0.02% / 1 min during on-site calibration
• Compact and lightweight (< 8 kg / 17.4 lbs) for easy transport
• Automatic evaluation per IEC, IEEE, and customized/local standards
• Quick commissioning (automatic test duration < 1 min)
• Enhanced workplace safety with tests running at a maximum of 120 V DC or 40 V AC
• Integration into testing routines via Remote Interface Control

CMC 356 is a versatile solution for testing all types of protection relays. With its powerful six current sources (up to 64 A / 860 VA per channel in three-phase mode), it effectively tests even high-burden electromechanical relays.

It is ideal for applications requiring maximum versatility, amplitude, and power, making it particularly valuable for commissioning engineers who need to perform wiring and plausibility checks using primary injection of high currents.

Key Features:

• Powerful current sources for high-burden electromechanical relay testing
• High current amplitudes suitable for 5 A relay testing
• High accuracy and versatility for static and numerical relay testing
• Integrated network for testing IEC 61850 IEDs
• 10-channel analog measurement and transient recording functionality (optional)
