Depends on what you want to achieve and what budget you have. Top of the range I look at CA8331 / CA8336. At the bottom end there are instruments like the Metrel MI2883 that are perfectly useable. Similar price range there is the PCE-360. Alternatively, if you want to build something up, then there are panel meters such as the PCE NDE range, that you can configure with your own CTs, which is likely the cheapest to buy, but requires building and won't be as portable as the instruments mentioned.
Intended use would be for the measurements in the prior question at the point of service interconnection with the utility. We use our utility meters and CT's for billing purposes, and are able to connect with an optical probe to pull up the vector diagrams to see the phase angles and, currents, voltages, and power factor for certain commercial/industrial sites using the meter manufacturers software, but could use a clamp meter similar to the Uni-T ut233 in the video as a valuable trouble shooting tool. This would be especially useful at residential sites which have less sophisticated watt-hour meters without the ability to measure reactive power. Residential loads are changing dramatically from what was once almost purely resistive loads to highly inductive ones, particularly with the introduction of EV charging led lighting loads, and ac to dc power supplies. There has also been an increase in harmonics on our systems due to the change in the loads consumers are using. Thanks for the reply. I think i may look into the AEMC 407 after doing a little digging. Same company makes the CA8331/CA8336 you mentioned.
@@patrickd4699 So if you are looking for spot testing, then these clamp styles meters are likely more financially viable rather than a full blown analyser. The only other meter I have seen similar to this that measures 3 phase power is the PCE Instruments PCE-PCM 1, I have never used it though. All the other clamp meter style power meters I have seen will only measure a balanced 3 phase load.
I’m looking at the UT243 for THD and related AC readings. Do you know if your concerns with the 233 have been addressed in the 243? Do you recommend anything else that can do THD and doesn’t break the bank?
What 3-phase power meter do you recommend for measuring PF, phase angles, KVA, KVAR, and Watts reliably?
