Electrical tests
(IR,PI, PD,TD,Cap, Tip up)
ARS is doing AC and DC tests for rotating machines through test equipment designed by Swiss Quartzteq brand test equipment. Results of such tests are a good way to determine faced stresses and aging of the machines.
Test scope
- AC and DC withstand tests
- Insulation resistance measurement
- Polarisation Index (PI)
- Partial discharge tests (PD)
- Loss factor / Tandelta Tests (TD)
- Capacitance tests (Cap)
- Tip up tests
- ELCID or Ring Flux (Core lamination tests)
ELCID test
Partial discharge, dissipation factor, capacitance measurements
Partial discharge on endwinding surface and its deterioration
Internal partial discharges due to voids and delaminations (the layers of mica become separated, a process known as delamination)
Vibration measurements
ARS Motor Servis experts do vibration tests through Erbessd Instruments vibration analysers. By this way all of dynamic parameters based on vibration are collected and analysed then reported
Cement mill motor vibration test
Farin mill motor vibration measurement
Hydro generator vibration test
Pump motor vibration test
Mill motor vibration test
ID Fan motor vibration measurement
Generator vibration tests
Gear box time wave form analysis
Bearings condition and deterioration are analysed through envelope spectrum analysis
Shaft alignment checks and improvements
Hydro generator site rebalance check (two planes)
Fan site rebalance (single plane)
