Dangerous Voltage: Staying Safe Using High Voltage Test Equipment
Electrical test instrumentation often must operate at medium…or even high…voltages. But even “low” voltage can kill you. What are the guidelines that an operator should consider when selecting and working with instrument test voltages?

DCM305E Earth Leakage Clamp Meter
Since there is no such thing as perfect insulation, if any conductor is raised to a potential above that of earth some current is bound to flow to earth from that conductor. The amount of current that flows is dependent on:Voltage on the conductorThe capacitive reactance between the conductor and earthResistance between conductor and earthCurrents that flow to earth are called leakage currents and are usually very small values, typically < 1 mA. However the amount of current that is required to cause distress or harm to a human being or animal is also small, these currents must be limited by circuit design to safe values.If this is not possible, then a 30 mA RCD (residual current device) or 30 mA RCBO (residual current device with overload protection) should be fitted for personal protection.

Configuring an Inrush Test
Current inrush testing is a common test that can be performed on transformers, motors and other equipment. This document shall describe how to configure the MPQ Analyzer to perform an inrush test. The MPQ Analyzer can record the voltage, current, active power, reactive power, apparent power, power factor and energy for every cycle for every active channel/phase, before and after the inrush. The MPQ Analyzer will also capture the inrush waveform for up to 10 seconds on each active channel.

The importance of the Guard Terminal in Insulation Testing
Insulation resistance measurement is one of the most widely used tests for power assets but, to achieve dependable results, it’s universally accepted that it’s essential to use a test set with a guard terminal. We look at why this is and examine the frequently neglected issue of guard terminal performance.
