Internal Resistance Measurement Module - RES

The RES internal module is designed for the measurement of the insertion resistance during the opening and closing times of a circuit breaker's auxiliary (resistive) contacts.

During open and close tests of high-voltage breakers performed by the CBA-32P©, the resistive states of the breaker contacts, when open or closed, may be viewed in the graphic reports generated by CBA Win©.

These graphic recordings show a value of 0.5 for the resistive state, while the open state is represented by a value of 0 and the closed state by a value of 1.

However, the exact value, in ohms, of this resistance is not known.

The purpose of this module is the instantaneous measurement of these values during open or close operations.

The resistance test results are displayed on the computer screen with the graphic and tabular reports. Moreover, the CBA Win© software supplied with all ZENSOL instruments functions with the RES module.

• Easy to use
• Allows the measurement of the insertion resistance of all contacts in one single test.
• Allows the instantaneous measurement of resistance of a circuit breaker's auxiliary (resistive) contacts.

• 8, 16 or 24 contact inputs
• Resistance range of 30 to 4000 ohms
• Precision of ±8%
• No external or additional power supply required; power is internally supplied by the CBA-32P instrument.
