Electric Cabinet Continuous Monitor

  • Continuously Monitor - 24/7
  • Detects electrical failures
  • Arcing, tracking and corona
  • Monitor any enclosed cabinet
  • Alarm for potential failure conditions
  • Prevent Arc Flash incidents

Prevent injury from Arc Flash & reduce unplanned downtime

The UE-ECM 586 continuously monitors enclosed electrical equipment for the onset of corona, tracking and arcing. Utilizing a 0-10 VDC or a 4-20 mA output proportional to the received signal and a heterodyned output, it will warn in real-time as soon as any of these conditions occur.

How it works

Corona, Tracking and Arcing generate ions. The ionization process generates ultrasonic emissions that are sensed by the ECM 586.

Set a threshold level for ultrasounds that exceed ambient noise levels to signal an alarm. It’s that simple. In addition you can use the heterodyned output to record the event once ultrasound levels exceed the threshold level.

The Risks

Corona exists above 1000 Volts, arcing can occur at any voltage, low medium or high. Tracking can exist at medium or high voltages.

Any one of these conditions can lead to flash over and failure if left unattended. The ECM 586 can alert operators of the presence of these conditions to prevent equipment outage and save money.

Corona, arcing and tracking can also produce an arc flash event. Arc flash kills and burns thousands of people a year. The tragedy of an operator being seriously injured can be avoided by letting the ECM 586 warn of these conditions.

Unique Features

The ECM 586 comes with an adjustable threshold level control. There are three outputs for your convenience: 4-20 mA, 0-10 VDC and Heterodyned (demodulated).

The heterodyned output enables users to determine the cause of an elevated ultrasound level and record events through a typical audio recording device (MP3 recorder, computer, etc.).

The ECM-586 can detect electrical failures before they cause a serious accident
