Line Voltage Isolation Relays are Problematic for Modern Meters

Today, many utilities continue to do KYZ metering installations the same way they were done 30 to 40 years ago. Yes, they may still work, but it is not the best engineering solution for today’s solid state meters and long-term reliability may be compromised. Let’s look at this more closely.

PV Systems with PulseConnex

Many organizations are looking to solar to provide relief from high electric bills, but with complicated net metering rates and data provided by the utility up to a month after occurrence, it can be hard to know how efficiently a solar PV array is operating.
