Amperage. Electrical contractor will increase to 200A
Amperage. 20 amps
1) Confirm that inter-probe spacing is accurate (note: low amperage (i.e. <20 amps) is commonly due to probe spacing being too large/wide (>2.5 cm)).
2) ONLY once probe spacing is confirmed, and if you are using a spacing <2.0 cm, should you consider increasing the Volts/cm parameter by 200 to 400 V/cm for the affected probe pairs. This change can be made in the parameter table while in “Edit” mode.
3) Consider increasing probe exposure by .5 cm or 1 cm (especially if amperage level is low for multiple probe pairs). Once the “tissue conductivity test” yields an amperage level within a range of 20-35 amps for all probe pairs, their “baseline” current level should be recorded and referred to throughout the treatment. The Number of Pulses is then edited to reflect 70 or 90 pulses for each probe pair to continue with the IRE treatment. Throughout the IRE treatment, the “Hint” box is monitored for “High-Current” warning messages. At the completion of each IRE treatment sequence, the Current graph in the Results tab is evaluated to ensure an adequate change in current has occurred for each probe pair. Each Probe Pair should experience an increase in current of at least 10 - 12 amps from their initial starting point. If a probe pair does not experience a rise in current of at least 10 - 12 amps, the physician should consider delivering an additional 70 or 90 pulses for that probe pair. The parameter table can be modified to only deliver energy to the desired probe pairs that have not reached an adequate rise in current. Upon completion of energy delivery, the current graph is evaluated in the same fashion as previously. Probe pairs that have not demonstrated a minimum of a 10 - 12 amp rise from their baseline value are considered for an additional 70 - 90 pulse sequence. It should be noted that the last 2 to 3 probe pairs may not achieve this 10 - 12 amp rise in current because treatment overlap and effective electroporation has already occurred. Tissue property changes during an IRE procedure are dependent on many factors. The decision to re-deliver pulse sequences for the probe pairs in question are the responsibility of the treating physician. It is believed that additional pulses beyond 270 pulses between a probe pair for a certain area of tissue does not add to the treatment zone. Once the treatment is complete, the physician may reposition the probes with a pullback of the probes or with an overlap placement to target additional tissue. When decidin...
Amperage. Kilowatt or Horsepower. Number of rotor bars. Number of motor fan blades. Drive end bearing model. (If it is a sleeve bearing indicate by writing “Sleeve”) Drive end bearing manufacturer. Number of non - drive end bearings. Non drive end bearing model. (If it is a sleeve bearing indicate by writing “Sleeve”) Non drive end bearing manufacturer. Obtain or calculate the major component forcing frequencies i.e. bearing defect frequencies, blade/vane pass frequencies, pole passing frequencies and rotor bar frequencies. Prior the final acceptance testing is performed, the following must be done: The motor to be tested for vibration must be mounted on a T-slotted steel block. The T-slotted steel block must be isolated from the floor and other nearby equipment that is operating must be switched off during testing to avoid interference. Other equipment’s vibration must not interfere with the machine being tested. The following specific frequencies’ vibration results must be supplied via spectrums and values (mm/sec) and recommendations thereafter. The acceptance criteria for bearing temperature rise when thermal equilibrium has been reached are; For Ball and Roller Bearings; 35°C on motors with 4 or more poles 40°C for 2 pole motors. For Sleeve and Tilting Pad Bearings;
