Use more expensive equipment with better sensitivities.
This is termed the accuracy of the measurement.

A C-V measurement is a Capacitance-Voltage measurement. Capicitance is the amount of charge stored Voltage is the power of the charge
I do not really know what you are trying to establish. Perhaps the answer is 'The degree of accuracy'. Hope that helps.
KVA is a measurement of power; kV is a measurement of voltage. You're asking "What is the power for voltage?", which makes no sense. Power = Voltage times current.
