Ronk Blocker®
Agricultural specialists have known for some time that low non-lethal voltages accessed to dairy animals can cause mastitis, affect animal behavior and materially reduce milk production. More recently, the same voltages have been known to cause problems in swine parlors, poultry houses, water fountains, swimming pools and homes.
Various studies have shown that voltages about 0.5 volts can be detected by animals that are very wet as is a dairy cow being washed down prior to milking. There is some evidence that humans are susceptible to a threshold voltage of approximately 1 volt when they are wet. Thus voltage below 10 volts, which previously the electrical industry has largely ignored as a non-problem, now, has a much greater interest and appreciation.
Since these low voltages may now have many sources, they have been variously called “tingle voltage”, extraneous voltage, or more generically called Stray Voltage. A number of studies and findings have identified methodical and logical methods for identifying the sources of the problems and eliminating them.
Stray voltages can come from many sources, both on and off the site. In most cases, the problems are the result of several sources simultaneous combined. On-site stray voltage can usually be resolved through a program of upgrading and reconnecting the wiring system and its various loads. Off-site stray voltage, which is of particular interest to the power supplier, can result from primary neutral currents, off-site faults, marginal groundings, etc.
Ronk Electrical Industries Inc. has developed the BLOCKER, which is a device designed to reduce the off-site contribution to the stray voltage problem. This simplifies the solution since any remaining problems have to be on-site in nature and can be handled and resolved accordingly.
