Three Phase Meter CL730S23 CT

The CL730S23 CT is a static three-phase revenue meter designed for industrial applications together with current instrument transformer connection.

CL730D22L is a three phase multi-function smart meter with modular design. It’s used for the accurate metering of commercial and industrial customer.

DTS719 is a transformer-operated three-phase smart meter with an embedded radio-frequency (RF) solution for local access.

In customer requests and tenders you can still find extensive requirements for the stability of the output settings.

In the last 100 years we had a lovely Ib for direct connected meters. Now the name has changed to nominal current In.

Electronic energy meters are like small computers. The need some time for starting up.

The load current can vary frequently with high amplitude. The test conditions in the older versions of the IEC62052-11 have all be static...

Another new test introduced by the IEC62052-11 Edition 2 is the repeatability test.

We need to figure out whether the occurring internal heat is causing a temporary error drift above the allowed limits for variation.
