For low and high voltage measurement it is a D type ground, and for especially high voltage measurement it's an A type ground. (Use in combination with a Yokogawa power monitor. Note that the CTW series current converters are for low voltages.) ...

For power monitors, you need to set up CT and VT ratios. (In the case of the PR300 power monitor, phase, wiring method, voltage range, and other settings are required in advance.) However, even when you enter these settings, there are times when the ...

Generally, when measuring high voltage and high current transformer signals, you use a VT (voltage transformer) and CT (current transformer). The ratios between the primary and secondary rated voltages and rated currents are the VT and CT ratios. For...

For each power monitor, normally you use 1 to 3 CTs. Single phase 2-wire = 1 CT; single-phase three-wire = 2 CTs; three-phase three-wire = 2 CTs, and three-phase four-wire = 3 CTs.

Check the active power. If the active power turns negative or extremely small, check the items below. The active power is negative when the power is regenerating. Items to check Is the CT attachment orientation correct? Is a CT connected to th...
