2432 type and 2433 type leakage clamp meters are mainly used to measure leakage current of power equipment in power system, such as transformers, switchgears and electric motors.
This handbook describes two basic methods for measuring transformer leakage current: clamping directly on an earthing conductor or clamping two-way wires together. It details the principle of operation, how the instrument displays the difference between incoming and outgoing currents, and the effect of external stray magnetic fields.
The document lists specifications for multiple KEW models (e.g., 2432, 2433, 2412, 2414, 2415, 2417, 2431, 2434), including measurement ranges, accuracy, frequency response, safety standards, dimensions, weight, power source, and available accessories such as carrying cases and test leads.
