The company P.A.S.D.T has created a safety system for high voltage transformers.

This module is available in two families: for submerged transformers and for dry transformers. They are complementary to the DGPT2, DMCR and COMEM security modules. These meet the NFC13-100 standard and completely meet the NFC17300 fire standard. Current systems are incomplete; no traceability or security prevents the circuit breaker cell from being restarted, and does not allow predictive maintenance. Each year, this causes exorbitant costs for companies and insurance companies and imposes significant restart times.
GILLES LEFEVRE Directeur

Hand Compatible with standards NF C13-100, NF C13-200 & NF C 17-300 and recently certified by the CNPP (Prevention & Risk Management) PASDT will very soon be strongly recommended by insurance companies and insurance companies. control and other bodies advice on the control of technical, human and environmental risks at work tenancy.

ALARM AND SIGNALING

Stand-alone module

The PASDT module manages the various alarms and signals even after the transformers are de-energized, which helps protect installations and personnel and prevent fires (environment).
The PASDT makes it possible to avoid a further accident when it is triggered.
Nobody can re-engage the HTBT as long as the problem persists (during an overpressure of the transformer or during an internal short-circuit): the transformer may explode!

SELF-MAINTAIN BATTERY

- Alarm management

The PASDT module has an independent battery allowing the complete management of the incident (traceability), thus avoiding a restart (accidental or imposed by the hierarchy not competent in the field.

DECOMMISSIONING LEVEL

Temperature, gas, pressure and lack of oil

The PASDT module acts on 4 standardized transformer de-energization levels (T1, T2, gas and pressure). signage and security remain in place to properly identify the alarm in question and react as quickly as possible. The temperature rise is generally due to an electrical fault causing local heating or to an overload of the transformer:
- T1 temperature of 90 ° reached and warning,
- T2 temperature of 100 ° reached and tripping.
- Pressure: overpressure is generally due to a short circuit in which the electric arc formed indirectly causes an increase in pressure.
- Gas (ozone, hydrogen: the release of gas is generally due to an electrical fault on the active part of the transformer, the arcing of which is not sufficient to cause an increase in pressure.

Les alerts are sent to the maintenance teams; the customer may have increased consumption and exceeded the transformer capacity! or the transformer is at the end of its life…
The main goal of the PASDT is to act before the standardized alerts whose T1 alerts.

INFORMATION SECURITY

No possibility of intrusion
Voice, SMS and data transfer on IOT 4.0 web portal

The PASDT module equipped with a GSM, which will have the function of transmitting information via telephone networks (SMS and voice message) to the various managers (management, maintenance team)
