The CTD Series of Dissipation factor Verification test sets from Avox Technologies has been developed to allow the end-user of dissipation factor (power factor) test sets to verify the accuracy of the readings of capacitance, dissipation factor, and voltage. The CTD series is designed to allow measurements of up to 12 k VAC (50/60 Hz).

The model CTD-1000 Capacitance/Dissipation factor Verification Set has a nominal capacitance value of 1000 pF (1nF) and a rotary selector switch that allows the setting of different levels of dissipation factor. These dissipation values can be user selected. In addition, the verification set has a built-in kilovolt meter for measurements up to 12,000 VAC.

This system requires mains voltage of 100 - 250 VAC for powering the kilovolt meter and required power relays for the dissipation factor values of 1%, 2% and 5% only. Capacitance/Dissipation factor operation of values at < 0.5% does not require any mains voltage (100-250 VAC).

This verification test box is easy to use. Simply attach the appropriate test leads and earth ground, then measure with dissipation factor (power factor) test equipment. For kilovolt readings and dissipation factor values ³ 1% an external, 100 - 250 VAC source is required.

The CTD-1000 incorporates a high precision standard capacitor that requires no external compensation. The dissipation factor standards are designed for the most stable readings.
