The Complete Guide to Electrical Insulation Testing - Techni-Tool
... A further advantage of this double-reading test, as it is sometimes called, is that it gives you a clearer picture, even when a spot reading says the insulation looks fine. For example, let’s say the spot reading on a synchronous motor was 10 megohms. Now, let’s assume that the double-reading check ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
