| 1 | Dismantling of old unservicable fuse kit, kat , existing IDMT O/C & E/F relays, burnt contactores replacement with new power logic P1F protection relay (model 'H') microprocessor type solid state electronic ON LOAD protection system with Plug Setting Multiplier of Relay, Time Setting Multiplier of Relay, Time vs. PSM Curve settings,Calculation of Relay Operation Time,1. Current setting. 2. Fault current level. 3. Ratio of current transformer. 4. Time / PSM curve. 5. Time setting. Output impedance shall be 3.0 to 5.0 percent,The card shall be manufactured such that it will maintain electrical properties, even under severe overload, under/over voltage and under/over frequency conditions. Input correction range shall be -30% to +20% of nominal input voltage. The system design shall be capable of operating at an input frequency range of -15% to +10% of nominal, without clearing protective devices or causing component failure within the Microprocessor Card. Upon turn on or restart, the output of the Microprocessor Card shall not exceed the specified output regulation limits. if the input voltage or frequency exceeds programmable minimum or maximum set points for a programmable time period (factory set for 10 seconds), the Microprocessor Card shall electronically shut off. When electrical parameters are back within acceptable limits for a programmable time period (factory set for 60 seconds), the Microprocessor Card shall automatically restart to provide conditioned power to the load. If the input parameters are within acceptable limits, but the output voltage is outside of acceptable programmed limits, the Microprocessor Card shall electronically shut off and require a manual restart. The Microprocessor Card shall be capable of operating at 100% rated load capacity continuously, 200% rated load for 10 seconds, 500% rated load for 1 second and 1000% rated load for 1 cycle. Operating efficiency shall be a minimum of 96%, typical at full load. Transverse-mode noise attenuation shall be 3dB down at 1000Hz and 40dB down per decade to below 50dB with a resistive load. Common-mode noise attenuation shall be 140dB or greater.The Microprocessor Card shall respond to any line voltage variation in 1/2 cycle while operating linear or non-linear loads, with a load power factor of 0.60 of unity. Peak detection of the voltage sine wave shall not be permitted to avoid inaccurate tap switching due to input voltage distortion. Line Voltage Regulation and Correction Time: Output regulation shall be +5%, -6%, given an input voltage variation of -30% to +30% for nominal, when within +/-5% of the nominal frequency. The Microprocessor Card output voltage shall be corrected to within +5%, -6% or less within 1 cycle per tap for an under voltage condition. For an over voltage condition, the output shall correct within 1 cycle directly to the appropriate tap without stair-casing intermediate taps. Typical correction time shall be 1 to 2 cycles. Load Regulation: No load to full load regulation shall be 3% typical under linear loading. |
| 2 | Notes: The Microprocessor Card shall be adjusted so that the combination of line voltage regulation and linear load regulation results in a maximum output voltage variation of +7% to -8% from nominal, when within +/-5% of the nominal frequency. Operating Frequency: The Microprocessor Card shall be capable of operating at +10% to -15% of the nominal frequency, 50Hz or 60Hz, with programmable high and low limits to alarm and electronically shut down the Microprocessor Card. Limits shall be set to +/-2Hz from nominal and electronic shutdown shall occur if limits are exceeded for 10 seconds. Once back within limits for a programmable time period of 60 seconds, the Microprocessor Card shall automatically restart. 2.5 Site Specific Data: Input Over Current Protection: The Microprocessor Card shall be provided with an integral, three pole, molded case, manually operated, thermal magnetic input circuit breaker rated at 125% of the full load input current.

On models where the input and output nominal voltages are the same, an integral break before make rotary maintenance bypass switch shall be provided to wrap around and isolate the Microprocessor Card. In this case, an input neutral conductor(s) shall be provided and the bypass switch shall bypass the output neutral, as well as, the phase conductors. The bypass switch circuitry shall be wired such that it cannot switch the unregulated power directly to the active load. Bypass switch actuation shall trip the Microprocessor Card input breaker, so that the facility load must then be reconnected using the input breaker.Alarms: |

PTC heaters are becoming more common as they are self-regulating. Body Material: Perforated Stainless Steel (SS) or Aluminum housing for corrosion resistance. Ceramic encased elements are also standard for high-durability industrial applications. Mounting: Flat-surface mounting or DIN rail mounting, typically located at the bottom of the VCB panel to allow heat to rise naturally (convection). Control & Safety Features Thermostat Integration: Often paired with an adjustable capillary-type thermostat (range: 30°C to 90°C to ensure the heater only operates when the temperature drops or humidity rises. Surface Temperature: Designed to keep surface temperatures below 200°C to prevent damage to nearby wiring. Protection Rating: Usually IP20 (since it is housed inside the IP55 or IP54 VCB Complete all as directed by Engr-in-charge.. Make :- EMCO/PARDEEP/EQUIV and for DATA Make Partner/Ecolibirium/MSME |
