24-channel On-line Partial Discharge Monitor for Temporary Installation
The HVPD Kronos® Portable Monitor is an on-line partial discharge (OLPD) continuous monitoring system for short-term installation. This monitor is designed to be moved around the network for short-term OLPD monitoring sessions of 1-3 months. It provides a diagnostic insulation condition assessment of in service plant, including switchgear, cables, transformers and rotating machines of 3.3 kV and above.
It can be used routinely or after a high PD level is detected with the PDS Insight™ or HVPD Longshot™ unit. The system trends PD activity over time and detects any load variances and intermittent PD activity. Uniquely in the market, we provide a dedicated service contract in conjunction with the monitoring technology and HVPD OLPD Measurements Database© to provide a comprehensive support to Condition-Based Management scheme.
