Retrofit Kit upgrades analog high-resistance grounding.
Press Release Summary:
PulserPlus(TM) utilizes digital display on control panel to provide readouts for neutral-ground voltage and neutral amperage values. Personnel can set limits to exact values. When PulserPlus detects ground fault, control unit activates alarm beeper and LED lights announce fault, as do FORM C dry alarm contacts. Digital data communications capability allows alarms to be sent to one or several remote locations as soon as they are activated. Data Log records date and time of fault.
Original Press Release:
Post Glover Introduces an All-Digital High Resistance Grounding System Retrofit Kit for Analog High Resistance Grounding Systems
Post Glover Resistors Inc. has developed a retrofit kit to upgrade Analog High Resistance Grounding Systems to its new state-of-the-art All-Digital High Resistance Grounding System (the PulserPlus (TRADEMARK)). It has a simplified and more accurate control panel, more extensive and superior alarm capability and precise data logging to help identify the ground fault source.
In the analog system, personnel have to rely on meter movements and/or inaccuracies shown on the control panel to know that a ground fault has occurred, but with the PulserPlus, the digital display on the control panel faceplate provides readouts for neutral-ground voltage and neutral amperage values. Personnel can set limits to exact values with all-digital PulserPlus.
With the old Analog system, fault warnings are announced locally by siren, horn or indicating lights from the control panel or remotely through auxiliary contacts. A warning could be announced without anyone noticing it for some time. In contrast, when the PulserPlus detects a ground fault, the control unit activates an alarm beeper (which has a silence push button) and LED lights announce the fault, as do FORM C dry alarm contacts. Another new feature, the digital data communications capability allows alarms to be sent to one or several remote locations as soon as they are activated, so that warnings cannot be missed. Unlike Analog systems, the PulserPlus all-digital programmable alarm delay can be used so that minor faults do not interrupt important production, but can be dealt with at a more convenient time.
The PulserPlus records the date and time of the fault on its Data Log, so maintenance personnel can compare the log to cyclical equipment operation, quickly isolate the source and schedule it for repair at a convenient time. Downtime is minimized. Continuous faults can be found using the pulse action of the control and the portable, clamp-on ammeter.
The Digital Control capability of PulserPlus has many advantages over the analog system. It guarantees precision setups, higher repeatability and improved accuracy. It also provides control and monitoring without the need for additional components.
