Electrostatic precipator EPS spark and arc problems


Thread Starter


Dear gentlemen

Kindly advice me A.S.A.P.

The Electrostatic precipator EPS for our Fuel oil boiler have current and voltage fluctuation for the unit transformer 1 & 2 and also spark and arc. The current fluctuation from 541mA to 190mA and the voltage from 50.84Kv to 46Kv.

Also there is a spark and arc:
Spark meter: between 4 to 8
Arc meter: between 3 to 4

There is no humidity in the EP and the Ash in the Hoppers was unloaded.

Kindly inform me if this limitation of ARC and SPARK are OK or I need to shutdown the EPS.

Thank you
