Since the advent of wide range power suppliesin electronic meters 480 volt self contained metering inirrigation wells has been a challenge for most utilities.Failures of 480 volt installations are often catastrophic.The meter can be destroyed or the meter and socket canbe completely obliterated with parts and pieces scat-tered many yards away.

There are many thoughts about why irrigationservices are susceptible to failure and most involvevoltage fluctuations, line disturbances or events likelightning strikes. Inrush currents have also been con-sidered a contribution to meter power supply failure. Inmost cases the meter’s power supply is the main sourceof the failure, ionizing the air in the meter and creatinga fault.

TSTM feels inserting a 2:1 toroidal transformerin the meter solves the problem. Vision Meteringworked with TSTM to securely mount their transformerinside the meter to effectively create a stable meter forirrigation wells. This meter has been field proven withgreat success.

Irrigation wells usually have either a 12S or 16S480 volt meter installed. Vision Metering makes bothversions with the toroidal transformer.
