- 1. Wikkelkop VPI Vacum druk impregnatie Onderhoud Alternator Generator EMD Predictief Explosion proof drukvast Winding head Winding end VPI Vacuum pressure impregnation Maintenance
- 2. Periodiek Voorspellend Stator Rotor Motor Periodical Predicitve Stator Rotor Motor High Voltage motors Its not wel known that frequent start/stop cycles can cause downtime! Situation
- 3. Isolatie Elektrische diagnose metingen EMD Rapport Hoogspanning Insulation Electrical diagnostic measurement EDM Report High voltage Reason to failure Start/stop cycles induces: High mechanical forces Movements on the winding heads Resulting in: Reduced lifetime Unwanted downtime Winding heads
- 4. Deelontlading Weerstand Polarisatie- index PI Verliesfactor Partial discharge Resistance Polarisation- index PI Dissipation factor What is the current state of your high voltage motor? Is failure near? Is your next startup the last startup? Questions? Breakpoint
- 5. Tangens delta analyse Nazicht Betrouwbaarheid Falen Tangens delta Analysis Inspection Reliability Failure Diagnose the current status onsite with specialist measurements Solution
- 6. Overhalen Herwikkelen Revisie Demontage Stilstand Overhaul Rewinding Revision Disassembly Downtime Problem: Detecting winding head problems from standard partial discharge measurements is difficult to interprete Solution: Only skilled engineers can identify beginning windinghead degradations with PD Peoples skills
- 7. Advies Hertelling Service Advise Repair Service Onsite On site Include specialist PD measurements in your preventive maintenance schedule and avoid unexpected downtime Added value Bob Van Loock Tel: +32 (0)3-644 19 61 Adress: Metropoolstraat 15 2960 Schoten Belgium
