Measuring and testing equipments for substations

Description

The MPC-5/50 GETEST is used to measure voltages between points on the ground (step potential) or between ground and conductive parts (contact potential) when there are leakage currents through the ground connection. These readings are required in Spain in transformer and distribution centres, as per MIE-RAT-13, BOE RD 337/2014, of 9 May. To conduct the test, the current source is connected between points far away from a ground line, and the voltage between two weights one-meter apart is measured (step potential), or between the ground and accessible conductive parts. The current source is adjusted to the desired value by means of a smartphone or tablet, allowing the measured data to be viewed and stored. 

• Step and contact meter, based on injecting current during one network cycle (20 ms) (maximum safety during use).
• Earth resistance measurement.
• Provides up to 50 A with a 12 Ω load. Maximum output voltage of 700 VAC.
• Maximum power equivalent to 30 kV·A, with a weight of just 45 kg.
• Remote control and display of the data measured on a smartphone or tablet, connected wirelessly to the device.
• Data storage on the smartphone or tablet itself, easily transferred to a PC.
